“What is the content of NCLEX-RN examination and how does the examinee answer those questions?”

Questions of the actual NCLEX-RN Examination were distributed to the following category:

Safe Effective Care Environment, under this category is the following sub-category -- Management of Care -- Infection Control Health Promotion and Maintenance

Physiological Integrity, under this category is the following sub-category -- Basic Care and Comfort -- Pharmacological and Parenteral Therapies -- Reduction of Risk Potential -- Physiological Adaptation

An update you must know about the actual NCLEX-RN examination:

Last April 2010, the questions about Management of Care were increased and questions about Reduction of Risk Potential were decreased. And according to the newsletter disseminated by NCSBN, the passing standard also increases. But do not be disturbed with this new info at hand, if you learn how to master the different concepts of nursing, starting with this concept “Fundamentals of Nursing”. Whatever type of questions you might encounter with the actual exam, I am sure that you can answer it correctly.

Processes Integrated into all Client Needs Categories

Nursing Process Caring Communication and Documentation Teaching and Learning The Test Duration is six (6) hours Minimum number of questions that you may answer is seventy five (75) And the maximum number of questions that you may answer is two hundred sixty five (265) The computer automatically stops when:

Maximum number of questions has been answered Six hours have elapsed Examinee‟s minimum level of competency has been established Examinee‟s lack of competency has been established NCLEX-RN also uses Computer Adaptive Testing (CAT) and the decision if you pass or fail is based on how many questions you answer correctly and the difficulty of the questions a candidate answers correctly. The Examination will not end until certainty of the pass/fail result is assured.

I. CULTURAL DIVERSITY

African-Americans

Direct eye contact with authority is viewed as rude; but it is an important part of communication among family members/significant others.

TIME FOR A SHORT QUIZ.

QUESTIONS A nurse is providing discharge instructions to a Chinese client regarding prescribed dietary modifications. During the teaching session, the client continuously turns away from the nurse. Which nursing action is appropriate? Continue the instructions, verifying client understanding Walk around the client so that the nurse constantly faces the client Give the client a dietary booklet and return later to continue with the instructions Tell the client about the importance of the instructions for the maintenance of health care 2. A nurse is preparing a plan of care for a client who is Jehovah‟s Witness. The client has been told that surgery is necessary. The nurse considers the client‟s religious preferences in developing the plan of care and documents that: Faith healing is practiced primarily Medication administration is not allowed Surgery is prohibited in this religious group The administration of blood and blood products is forbidden 3. Which of the following meal trays would be appropriate for the nurse to deliver to a client of Jewish faith who follows kosher diet? Pork roast, rice, vegetables, mixed fruit, milk Crab salad on a croissant, vegetables with a dip, potato salad, milk Sweet and sour chicken with rice and vegetables, mixed fruit, juice Fettucini alfredo with shrimp and vegetables, salad, mixed fruit, iced tea 4. An ambulatory care nurse is discussing preoperative procedures with a Chinese-American client who is scheduled for surgery the following week. During the discussion, the client continually smiles and nods the head. The nurse interprets this nonverbal behaviour as: Reflecting a cultural value An acceptance of the treatment The client is agreeable to the required procedures The client understands the preoperative procedure

5. A Chinese-American client experiencing anemia, which is believed to be a yin disorder, is likely to treat it with: Magnetic therapy Intercessory prayer Foods considered to be yin Foods considered to be yang ANSWERS AND RATIONALE 1) A - Most Chinese maintain a formal distance with others, which is a form of respect. Many Chinese are uncomfortable with face-to-face communications, especially when eye contact is direct. If the client turns away from the nurse during a conversation, the most appropriate action is to continue with the conversation. Walking around to the client so that the nurse faces the client is in direct conflict with the cultural practice. The client may consider returning later to continue with the explanation as a rude gesture. Telling the client about the importance of the instructions for the maintenance of health care may be viewed as degrading. 2) D - Among Jehovah‟s Witnesses, surgery is not prohibited, but the administration of blood and blood products is forbidden. Faith healing is forbidden in this religious group. Administration of medication is an acceptable practice, except if the medication is derived from blood products. 3) C - In the Jewish religion, those who are kosher believe that the dairy-meat combination

is not acceptable. Pork and pork products are not allowed in the traditional Jewish religion. Only fish that have scales and fins are allowed; meats that are allowed include animals that are vegetable eaters, cloven-hoofed, and ritually slaughtered. 4) A - Nodding or smiling by a Chinese-American client may reflect only the cultural value of interpersonal harmony. This nonverbal behavior may not be an indication of agreement with the speaker, an acceptance of the treatment, or an understanding of the procedure. 5) D - In the yin and yang theory, health is believed to exist when all aspects of the person are in perfect balance. Yin foods are cold and yang foods are hot. Cold foods are eaten when one has a hot illness and hot foods are eaten when one has a cold illness. Options A and B are not associated with the yin and yang theory.

II. ETHICAL AND LEGAL ISSUES

Advance Directive

It is a written document that provides directions concerning the provision of care when a person is unable to make his/her own treatment choices. Two types of advance directive: a) Living Will – it is the expression of the person‟s wishes regarding end-of-life care. It is prepared by a competent adult that provides direction regarding medical care in the event of the person‟s incapacitation or otherwise becoming unable to make decisions personally. b) Durable Power of Attorney – I is an authorization that enables any competent individual to name someone to exercise decision-making on his/her behalf under specific circumstances. Example, end-of-life situation.

Clarifying Unclear/Inappropriate Physician’s Order

Clarify the order with the physician who gave the order Contact nurse manager/supervisor if no resolution occurs regarding the order in question

Floating

It is acceptable and legal practice Nurse cannot refuse to float; but the nurse should not assume responsibility beyond level of experience or qualification The nurse should inform the supervisor of any lack of experience in caring for the type of clients on the new nursing units The nurse should be given an orientation to the new unit Floating nurse should be assigned with patients with stable conditions; or similar to his/her training or experience Floating nurse should not be assigned to patients who are for discharge and who require patient teaching

Good Samaritan Laws

- These laws encourage health care professionals to assist in emergency situations without fear of being sued for the care provided

Informed Written Consent

Physician not the nurse, is the primary responsible to secure written consent Nurse may sign as a witness. It attests that the client signed the consent Written consent is legal when: The person is in legal age (18 y/o and above) The consent is secured without force, duress, or coercion The person is not under the influence of drugs or alcohol The person is not mentally incapacitated Parents or guardian can signed for minors and persons who are physically or mentally

incapacitated Minors who are married or emancipated from the parents and those seeking for

treatment for STD‟s can signed an informed consent Written consent can be waived in time of emergency to save the life of the person Validity of informed consent is 24 hours. If the procedure is postponed, secure another

consent Secure consent for each procedure

Organ Donation

Age requirement is 18 y/o and above before signing a form for organ donation Informed choice to donate an organ may be through written document signed by the client prior to death, a will, a donor card, or an advance directive Family member or legal guardian may authorize organ donation if the client is dead

Physician’s Orders

Nurses is duty-bound to carry out a doctor‟s order except when the nurse believes that the order is inappropriate Nurses who carry out inaccurate order is legally responsible for his/her action

Telephone Orders

Date and time the entry Repeat (read back) the order to the physician and record the order Sign the order begin with the t.o., write the doctor‟s name, and then sign the order; e.g. (t.o. Dr. Alec Tinio/ your signature RN It is necessary that the doctor countersign the order within the time frame based on the agency policy (usually 24 hours)

Use of Restraints

Written consent is needed coming from relatives/significant others Secure consent for each episode of application of restraints PRN order: legally unacceptable Apply soft restraints Secure restraints at he bed frame, not on the side rails Check restraint application every 15-20 minutes Release restraints every 2 hours for 30 minutes Change restraints every 24 hours

Documentation

For Narrative Documentation

it should be accurate, complete, factual, and objective use a black pen document care, medications, treatments, and procedures as soon as possible, after completed document responses to interventions document consent for a refusal of treatments document calls made to other health care providers

use appropriate abbreviations in case of error, draw one line through the error, initial and date never erase any entry, do not use correction fluid do not leave blank spaces on documentation forms. Avoid judgmental or opinionated statements, such as “uncooperative client.” Do not document for others or change documentation for other individuals

For Computerized Documentation

use only the user identification (ID) code, name, or password maintain privacy and confidentiality of documented information printed from the computer

Principle of Confidentiality

Information about a client be kept private Information in the client‟s record is accessible only to those providing care to the client No one else is entitled to that information unless the client has signed a Consent for Release of Information that identifies with whom information may be shared and for what purpose. Discussing clients outside the clinical setting, telling friends, or family about clients or even discussing clients in the elevator with other workers violates client‟s confidentiality. The clients has a right to review the records pertaining to his/her medical care and to have the information explained or interpreted as necessary, except when restricted by law

Incident Reports/Variance Reports

A tool used as a means of identifying and improving care. The reports should be complete, accurate, and factual. The reports should not include opinions or interpretations. The report form should not be copied or placed in the client„s record. It is not a substitute for a complete entry in the client‟s record regarding the incident.

Controlled Substances

Nurses may administered controlled substances (narcotics, depressants, stimulants, and hallucinogens), only under the directions of a physicians or other authorized providers. Controlled substances must be kept securely locked, and only authorized personnel should have access to them.

Reporting Responsibilities. The following situations need to be reported to the Local Authority. This is a LAW. Failure to report any of these situations is a malpractice.

Communicable diseases Abuse: sexual, child, wife, husband, elderly abuse. (Whenever abuse is suspected, it should be reported to the local authority. It will be the court to prove or disprove abuse.) gunshot/ stab wounds vehicular accidents assault homicides

Clients Advocacy Involves concerns and actions on behalf of another person in order to bring about change. 3 Elements of Advocacy

1. Mediate

2. Inform

3. Support

MORAL PRINCIPLES

1. Beneficence - means doing and promoting good.

e.g., Administering pain medications.

Practicing asepsis to prevent infection.

Promoting safety of restless and confused clients.

Providing psychosocial support to an anxious client.

2. Nonmalefincence - means to avoid doing harm, to remove from harm, and to prevent harm.

e.g., protecting the client from a practitioner who practices drug abuse.

Reporting abuse prevent further victimization.

3. Autonomy – right to make one‟s own decision

4. Fidelity – being faithful to agreement and promises

5. Veracity – telling the truth

6. Justice - fairness

TORTS AND CRIMES

- These are legal wrongs committed against a person or property.

CRIME - Results in prison term or fine or short jail sentence to punish offender.

a. Felony - A crime of serious nature.

b. Misdemeanor - An offense punishable by imprisonment of less than one year or a fine less than 1,000 dollars. Does not amount to a felony. c. Manslaughter - A second degree murder. It is unintentional killing. e.g., accidental administration of overdose narcotics that resulted to death of the clients.

TORTS - Result in civil trial to assess compensation for plaintiff

1. Intentional Torts:

I. Assault and Battery

a. Assault – is the threat of touching another person without his/her consent

b. Battery – is the actual carrying out of such a threat

II. Defamation of Character - is a communication that is false or made with careless disregard for the truth, and results in injury to the reputation of the person

a. Libel – defamation by means of print, writing, or pictures

b. Slander - is defamation by spoken word, stating unprivileged or false words by which the reputation of the person is damaged

III. Fraud - is the wilful, purposeful misrepresentation of self or an act that may cause

harm to a person or property

IV. Invasion of Privacy - is disclosure confidential information to an inappropriate third party (subjects the nurse to invasion of privacy even if the information is true).

V. False Imprisonment – occurs when a client is not allowed to leave a health care facility when there is no legal justification to detain the client

2. Unintentional Torts

I. Negligence – mistake or failure to be prudent. An act of omission or commission II. Malpractice – is negligence in the practice of profession (e.g. error in sponge counts) To prove malpractice, four elements are necessary

a. a duty of the nurse to the client b. a breach of duty on the part of the nurse c. an injury to the client d. a causal relationship between the breach of duty and the client subsequent injury Potential Malpractices Situations in Nursing medication error sponge count error burning a client client falls

mistaken identity loss/damage of client‟s property failure in reporting crimes, torts, and unsafe practice

“Only the Task not the Accountability may be Delegated to another”

Best Practice: Always ensure client safety

Death and Dying

Right of Informed Refusal – a competent adult has the right to refuse treatment, even life-sustaining treatment Do Not Resuscitate (DNR) Order – a written order must be present and must be reviewed on a regular basis. The client or his/her legal representative must provide informed consent for the DNR status. Both DNR and cardiopulmonary resuscitation (CPR) must be clearly defined so that other treatments, not refused by the client will be continued. Euthanasia – physician or nurse-caused death (active euthanasia), deliberately hastening a person‟s death, is considered murder in all states and almost all other countries

Pronouncement of Death

in some States, the nurse may pronounce death at the bed side in most States, however, the physician has the legal responsibility of pronouncing the person dead. “To be safe in answering, always choose PHYSICIAN.” Death Certificate – the physician is responsible for signing a death certificate

Care of the Body – the nurse is responsible for preparing the body for the morgue or mortuary. Consider the cultural practices and wishes of the family. Treat the body with dignity.

Rigor Mortis – stiffening of the body (occurs 2-4 hours)

position the body, the dentures, close the mouth and eyes before RM set in Algor Mortis – decrease in body temperature (1C/hr)

Livor Mortis – discoloration of the skin because of the RBC breakdown

Management:

make the body appear natural and comfortable allow the family to view the patient‟s body place the body in supine positions, the arms at the side and palms down place one pillow under the head and shoulder to prevent blood from discoloring the face place absorbent pads under the buttocks to take up any feces or urine apply identification tags, one on the ankle and one at the wrist wrap the body in shroud, place the third tag for identification

III. LEADERSHIP AND MANAGEMENT Priorities of Care needs that are life threatening are given highest priority actual before potential concerns consider time constraints and available resources needs that are identified as important by the client are given highest priority use Maslow‟s hierarchy of needs (physiologic before psychosocial needs) use ABC‟s; patent airway is always priority unstable before stable clients client first before equipment do not delegate client who need:

to be assessed those who need health teachings those who need to be evaluated those with unstable conditions

DELEGATION transference of responsibility and authority for the performance of an activity to a competent individual Five Rights of Delegation Right Task – appropriate activities Right Circumstances – assess health status. Match complexity of activity with competency of the health care worker. Right Person Right direction and communication Right supervision/evaluation

CNA/Unlicensed Nursing Assistant Undergo certification examination May care for clients with stable conditions May perform standard nursing procedures: VS - taking Comfort measures Hygienic measures Activity, mobility, exercise Collection of specimen Enema administration Obtaining equipment LPN/LVN Undergo licensure examination (NCLEX-PN/VN) May perform standard nursing procedures and more complicated nursing procedures: Wound dressing changes Irrigation of wounds Colostomy care Enteral feedings Administration of medications (oral, subcutaneous, intramuscular) Administration of basic IV fluids (no IV meds and electrolytes added to IV fluids like Potassium Chloride) Catheterization May care for clients with stable conditions

Leadership Theories 1. Bureaucratic – relies on organization‟s rule and policy

2. Autocratic – make decision for the group

3. Laissez-faire – recognizes the group‟s need for autonomy and self-regulation; “hands-off approach”

4. Democratic – encourages group discussion and decision making

Principles of Management

1. Authority – legitimate right to direct the work to others

2. Accountability – ability to assume responsibility for one‟s action and its consequences

3. Responsibility – obligation to complete a task

Principles in Rooming-In

Cohorts (similar medical diagnosis or mode of transmission of disease) may be roomed-in as long as one does not have another type of contagious infection. Consider age and gender of clients. Clients of the same age group and gender may be roomed-in Clients with airborne infections should be confined in private rooms Immune-compromised clients should not be roomed-in with clients who have infections.

Case Management Assignment of health care provider to assist a patient in assessing health and social service systems to assure that all required services are obtained Who requires Case Management? age 65 with chronic diagnostic state,

lives alone newly diagnosed diabetic limited income preventing prescription

purchases confused or unstable to make

decisions

weakness related to CVA may require change in living

arrangements may need medical equipment may need home health follow-up admitted from board and care

Let us evaluate . . . 1. A new unit nurse manager is holding her first staff meeting. The manager greets the staff and comments that she has been employed to bring about performance improvement. The manager provides a plan that she developed, as well as a list of tasks and activities for which each staff member must volunteer to perform. In addition, she instructs staff members to report any problems directly to her. What type of leadership style do the new manager‟s characteristics suggest?

autocratic situational

democratic laissez-faire

2. A new nursing graduate is attending an agency orientation regarding the nursing model of practice implemented in the health care facility. The nurse is told that the nursing model is a team nursing approach. The nurse understands that planning care delivery will be based on which characteristic of this type of nursing model of practice? a task approach method is used to provide care to clients managed care concepts and tools are used in providing client care an RN leads nursing personnel in providing care to a group of clients a single RN is responsible for providing nursing care to a group of clients 3. The nurse manager has implemented a change in the method of the nursing delivery system from functional to team nursing. A nursing assistant is resistant to the change and is not taking an active part in facilitating the process of change. Which of the following is the best approach in dealing with the nursing assistant? ignore the resistance exert coercion with the nursing assistant provide a positive reward system for the nursing assistant confront the nursing assistant to encourage verbalization of feelings regarding the change 4. The nurse manager of a critical care unit must speak to a staff nurse about an employment issue, tardiness. Nearly every day during the past week, the staff nurse has been from 5 to 20 minutes late, missing portions of the daily client status conferences. The manager had verbally counselled the staff nurse 3 months prior to the latest incidence of tardiness about the same issue. When they meet, the nurse manager‟s best approach to the staff nurse is to: send the staff nurse to Human Resources Department for counselling ask the staff nurse to tell the manager about the facts surrounding the tardiness inform the staff nurse that, based on unreliability caused by tardiness issues, the nurse is terminated Provide the staff nurse with a detailed notice of intent to terminate if any further incident of tardiness occurs.

5. A nurse is giving a report to a nursing assistant who will be caring for a client who has hand restraints. The nurse instructs the nursing assistant to assess the skin integrity of the restrained hands every:

2 hours 3 hours

4 hours 30 minutes

ANSWERS AND RATIONALE 1) A - The autocratic leader is focused, maintains strong control, makes decisions, and, addresses all problems. Furthermore, the autocrat dominates the group and commands rather than seeks suggestions or input. In this situation, the manager addresses a problem (performance improvement) with the staff, designs a plan without input, and wants all problems reported directly back to her. A situational leader will use a combination of styles, depending on the needs of the group and the tasks to be achieved. The situational leader would work with the group to validate that the information that the leader gained as a new employee was accurate and that a problem existed, and would then take the time to get to know the group and determine which approach to change (if needed) would work best according to the needs of the group and the nature and substance of the change that was required. A democratic leader is participative and would likely meet with each staff person individually to determine the staff member‟s perception of the problem. The democratic leader would also speak with the staff about any issues and ask the staff for input with developing a plan. A laissez-faire leader is passive and nondirective. The laissez-faire leader would state what the problem was and inform the staff that the staff needed to come up with a plan to “fix it.” 2) C - In team nursing, nursing personnel are led by a registered nurse leader in providing care to a group of clients. Option A identifies functional nursing. Option B identifies a component of case management. Option D identifies primary nursing. 3) D - Confrontation is an important strategy to meet resistance head on. Face-to-face meetings to confront the issue at hand will allow verbalization of feelings, identification of problems and issues, and development of strategies to solve the problem. Option A will not address the problem. Option B may produce additional resistance. Option C may provide a temporary solution to the resistance but will not address the concern specifically. 4) D - In general, the process for corrective action begins with an oral reprimand and then a written reprimand. In addition to the written reprimand, the manager should be prepared to work with the staff nurse to develop a plan of action. The manager must notify the staff nurse, in writing, of the potential for termination based on tardiness. If this were the first instance, the manager would ask the staff nurse to describe the facts surrounding the tardiness in order for the manager to assist the staff nurse with problem-solving strategies or to examine the need for moving the staff nurse to a different shift, if indicated. Managers are expected to deal with personnel issues, and tardiness is a frequent problem that managers face. Human resources serve as a support to the actions of the manager, but do not assume the role of dealing with the employee. Managers must give notice prior to termination as a risk management strategy. 5) D - The nurse should instruct the nursing assistant to assess restraints and skin integrity every 30 minutes. Agency guidelines regarding the use of restraints should always be followed.

IV. BASIC PHARMACOLOGY (including Herbal Medicines) Types of Doctor’s Order Standing Order – it is carried out until the specified period of time or until it is discontinued by another order Single Order – it is carried out for one time only STAT Order – it is carried out at once or immediately PRN Order – it is carried out as the patient requires Parts of Legal Doctor’s Order - Name of patient - Date and time - Name of drug - Dose of drug - Route of administration - Times or frequency - Signature of the physician PRINCIPLES IN ADMINSTERING MEDICATION 1. Observe the “7 Rights” of drug administration Right drug – read the label three times Right dose – know the usual dose of the drug. Calculate the correct amount Right time – standard time may be followed in the institution Right route – check the route of administration Right patient – identify patient by: checking the ID band (most accurate patient identifier) or asking him to state his/her name (not accurate for confused clients) Right recording – sign medication sheet immediately after administration Right approach 2. Practice Asepsis – wash hands before and after preparing medications Nurses who administer medications are responsible for their own actions. Question any order that you consider incorrect (may be unclear or inappropriate) Be knowledgeable about the medications that you administer. Know the action, indication, nursing responsibilities, side effects of the drugs Fundamental Rule: “Never Administer an Unfamiliar Medication” 3. Keep narcotics in locked place

4. Use only medications that are clearly labelled container. Relabeling of drugs is the responsibility of pharmacist 5. Return liquid that are cloudy in color to the pharmacy 6. Before administering the medication, identify the client correctly 7. Do not leave the medications at the bed side. Stay with the client until he actually takes the medications 8. The nurse who prepares the drug administers it. Only the nurse who prepared the drug knows what that drug is. Do not accept endorsement of medications. 9. If the client vomits after taking the medication, report this to the nurse in charge or physician 10. Preoperative medications are usually discontinued during the postoperative period unless ordered to be continued 11. When a medication is omitted for any reason, record the fact together with the reason 12. When a medication error is made, report it immediately to the nurse in charge or physician. To implement necessary measures immediately. This may prevent any adverse effects of the drug

ROUTES OF DRUG ADMINISTRATION

1. Oral Medication - Most common method of drug administration and generally the safest route. Absorption will usually take in GIT. - Onset is slower compare to others Types of Oral Drugs

a. Solid Preparation – tablets, capsules, and pills Remember: enteric-coated tablets and time-released capsules are never crushed or chewed b. Liquid Preparation – elixirs, syrups, and suspensions. They are best administered by using calibrated cup (read at the eye level).

Other Oral Form Drugs

a. Sublingual – drugs are placed under the tongue b. Buccal – drugs are placed in the inner cheek Rule: never swallow the drug and do not follow with water. If nitro-glycerine is given, advise patient not to smoke.

Safety in administering Oral Medications - might cause aspiration and choking (especially large capsules and tablets) - assess for gag reflex, dysphagia, or altered LOC - client who is NPO Note: if drug has offensive taste, offer oral hygiene.

2. Topical Medication

- applied to the skin by spreading it over an area, soaking or medicated bath (causes either local or systemic effect depending on duration of application).

Note: Nurse should done gloves when administering this type of drug.

3. Inhalation Medication

Nasal inhalation – oxygen is administered by this route

Oral inhalation

MDI (Metered-dose inhaler)

2 inches away from the mouth Inhale 2-5 seconds Hold breath for 10 seconds Wait 1-2 minutes before each puff Note: to know if the canister is still packed with drug, simply put it in basin with water. If it floats, it is empty.

Nebulizer

Dilute to sterile 0.9% NaCl (2-5 ml) Attach oxygen to nebulizer (8L/min) Breathe normally through mask or mouthpiece for 5-15 minutes

Note: offer Oral Hygiene

4. Eye Medication (Optic)

Effects: Miotics - pupil constriction

Mydriatics – pupil dilation

Types:

Liquid – 2 gtts (lower conjunctival sac)

Ointment – 2 cm (inner to outer canthus)

Note:

no to cornea press the nasolacrimal gland if drug will cause systemic effect don‟t let the tip of the canister touch any part of the eye sitting position is required

Note: Eye assessment? Dim the light prior to eye examination

5. Ear Medication (Otic) Position: lateral position Age below 3 y/o – pull the pinna down and back Above 3 y/o – pull the pinna up and back Solution - side of the ear Temp of solution – warm Press the tarsus of the ear 3 times for absorption Place earplug for 5 minutes Note: if the ear canal is obstructed by seed, don‟t flush with water. If an insect goes inside the ear, use flashlight

6. Parenteral Route

– is a medication administration is by needle.

Intradermal route of medication administration- it is a parenteral route of medication administration by injecting the needle under the epidermis.

The site are the inner lower arm, upper chest and back, and beneath the scapula Indicated for allergy and tuberculin testing and for vaccinations Use the needle gauge 25,26,27 needle length: 3/8", 5/8", or 1/2" Needle at 10-15 degrees angle: bevel up Inject a small amount of drug slowly over 3 to 5 seconds to form a wheal or bleb Do not massage the site of injection. To prevent irritation of the site, and to prevent absorption of the drug into the subcutaneous.

I. SUBCUTANEOUS route of medication administration - for vaccines, heparin, preoperative medication, insulin, narcotics

The site: - outer aspect of the upper arms - anterior aspect of the thighs - abdomen - scapular areas of the upper back - ventrogluteal - dorsogluteal

Only small dose of medication should be injected via SC route Rotate site of injection to minimize tissue damage Needle length and gauge are the same for ID injections Use 5/8 needle for adults when the injection is to administer at 45 degree angle; 1/2 is use at 90 degree angle For thin patients: 45 degree angle needle

For obese patient: 90 degree angle needle For heparin injection: do not aspirate and do not massage the injection site to prevent hematoma formation. For insulin injection: do not massage to prevent rapid absorption which may result to hypoglycemic reaction. Always inject insulin at 90 degrees angle to administer the medication in the pocket between the subcutaneous and muscle layer. Adjust the length of the needle depending on the size of the client

II. INTRAMUSCULAR route of medication administration needle length: 1", 1 1/2", 2" to reach the muscle layer Clean the injection site with alcoholised cotton ball to reduce microorganisms in the area Inject the medication slowly to allow the tissue to accommodate volume

Sites:

a. Ventrogluteal site The area contains no large nerves, or blood vessels and less fat. It is farther from the rectal area, so it is less contaminated Position the client in prone or side-lying When in prone, curl the toes inward When in side-lying, flex the knee and hip. These ensure relaxation of the gluteus muscles and minimize discomfort during injection To locate the site, place the heel of the hand over the greater trochanter, point the index finger toward the anterior superior iliac spine, and then abduct the middle(third) finger. The triangle formed by the index finger, the third finger and the crest of the ilium is the site.

b. Dorsogluteal site

Position the client similar to the ventrogluteal site The site should not be used in infant under 3 years old because the gluteal muscles are not well developed yet To locate the site, the nurse draws an imaginary line from the greater trochanter to the posterior superior iliac spine. The injection site is lateral and superior to this line Another method of locating this site is to imaginary divide the buttock into four quadrants. The upper most quadrant is the site of injection. Palpate the crest of the ilium to ensure that the site is high enough Avoid hitting the sciatic nerve, major blood vessel or bone by locating the site properly

c. Vastus Lateralis

Recommended site for infant Located at the middle third of the anterior lateral aspect of the thigh Assume back-lying or sitting position

d. Rectus Femoris site

Located at the middle-third, anterior aspect of the thigh

e. Deltoid site Not used often for IM injection because it is relatively small muscle and is very close to the radial nerve and radial artery To locate the site, palpate the lower edge of the acromion process and the midpoint on the lateral aspect of the arm that is in line with the axilla. This is approximately 5cm(2 in) or 2 to 3 fingerbreadths below the acromion process

f. IM injection - Z tract injection

Used for parenteral iron preparation. To seal the drug deep into the muscles and prevent permanent staining of the skin

Retract the skin laterally, inject the medication slowly. Hold retraction of skin until the needle is withdrawn Do not massage the site to prevent leakage into the subcutaneous.

GENERAL PRINCIPLES IN PARENTERAL ADMINISTRATION 1. Check doctor's order

2. Check the expiration for medication - drug potency may increase or decrease if

outdated

3. Observe verbal and non-verbal responses toward receiving injection. It can be painful,

client may have anxiety, which can increase the pain

4. Practice asepsis to prevent infection. Apply disposable gloves

5. Use appropriate needle size. To minimize tissue injury

6. Plot the site of injection properly. To prevent hitting nerves, blood vessels, bones

7. Use separate needles for aspiration and injection of medications to prevent tissue

irritation

8. Introduce air into the vial before aspiration. To create a positive pressure within the

vial and allow easy withdrawal of the medication

9. Allow a small bubble (0.2 ml) in the syringe to push the medication that may remain

10. Introduce the needle in quick thrust to lessen discomfort

11. Either spread or pinch muscle when introducing the medication. Depending on the size

of the client

12. Minimized discomfort by applying cold compress over the injection site before

introduction of medication to numb nerve endings

13. Aspirate before introduction of medication. To check if blood vessel had been hit

14. Support the tissue with cotton swabs before withdrawal of the needle. To prevent

discomfort of pulling tissues as needle is withdrawn

15. Massage the site of injection to haste absorption

16. Apply pressure at the site for few minutes. To prevent bleeding

17. Evaluate effectiveness of the procedure and make relevant documentation.

METHOD OF DRUG ADMINISTRATION INTAVENOUSLY

1. A mixture within large volumes of IV fluids

2. By injection of bolus, or small volume, or medication through an existing intravenous

infusion line or intermittent venous access (heparin or saline lock)

3. By "piggyback" infusion of solution containing the prescribed medication and a small

volume of IV fluid through an existing IV line

Most rapid route of absorption of medications Predictable, therapeutic blood levels of medication can be obtained The route can be used for clients with compromised gastrointestinal function or

peripheral circulation Large dose of medications can be administered by this route The nurse must closely observe the client for symptoms of adverse reactions The nurse should double-check the six rights of safe medication

If the medication has an antidote, it must be available during administration When administering potent medications, the nurse assesses vital signs before, during

and after infusion

NURSING INTERVENTIONS IN I.V. INFUSION

a. Verify doctor's order

b. Know the type, amount, and indication of IV therapy

c. Practice strict asepsis

d. Inform the client and explain the purpose of IV therapy to alleviate client's anxiety

e. Prime IV tubing to expel air. This will prevent air embolism

f. Clean the insertion site of IV needle from center to the periphery with alcoholized cotton ball to prevent infection

g. Shave the area of needle insertion if hairy. Ask permission to the client

h. Change the IV tubing every 72 hours. To prevent contamination

i. Change IV needle insertion site every 72 hours to prevent thrombophlebitis

j. Regulate IV every 15-20 mins. To ensure administration of proper volume of IV fluid as ordered

k. Observe for potential complications.

THREE TYPES OF I.V. FLUIDS

a. Isotonic solution - it has the same concentration as the body fluid.

D5W NaCl 0.9%

Plain Ringer's lactate Plain normosol M

b. Hypotonic - has lower concentration than the body fluids. Too much of this fluid can swell the body's cell.

NaCl 0.3% c. Hypertonic - has higher concentration than the body fluids. Too much of this fluid can make the body's cell shrink.

D10W D50W

D5LR D5NM

COMPLICATIONS OF I.V. INFUSION

1. Infiltration - the needle is out of vein, and fluids accumulate in the subcutaneous tissues.

Assessment

Pain, swelling, skin is cold at needle site, pallor of the site, flow rate has decreases or stops Nursing Intervention: Change the site of the needle Apply warm compress. This will absorb edema fluids and reduce swelling

2. Circulatory Overload- this complication of I.V. infusion results from administration of excessive volume of I.V. fluids.

Assessment Headache, flushed skin, rapid pulse Increase BP, weight gain, syncope and faintness Pulmonary edema, increase volume pressure Coughing, tachycardia, shock Nursing Intervention: Slow I.V. infusion to KVO - at least 10 gtts/min Place patient in high-fowler's position to enhance breathing Administer diuretic, bronchodilator as ordered.

3. Drug Overload - this complication of I.V. infusion occurs when the patient receives an excessive amount of fluid containing drugs Assessment

Dizziness, shock Fainting Nursing Intervention: Slow I.V. infusion to KVO Take vital signs Notify the physician

4. Superficial Thrombophlebitis - this complication of I.V. infusion is due to overuse of a vein, irritating solution or drugs, clot formation, large bore catheters

Assessment Pain along the course of vein Vein may fell hard and cordlike Edema and redness at needle insertion site Arm feels warmer than the other arm Nursing Intervention Change I.V. site every 72 hours Use large veins for irritating fluids Stabilize venipuncture at area of flexion Apply cold compress immediately to relieve pain and inflammation; later with warm compress to stimulate circulation and promotion absorption Do not irrigate the I.V. because this could push clot into the systemic circulation

5. Air Embolism - air manage to get into the circulatory system; 5 ml of air or more causes air embolism. Take note that it is a life-threatening conditio9n.

Assessment Chest, shoulder or back pain Hypotension Dyspnea Cyanosis Tachycardia Increase venous pressure Loss of consciousness Nursing Intervention Do not allow the I.V. bottle to run dry Prime I.V. tubing before starting infusion Turn patient to left side in the trendelenburg position. To allow air to rise in the right side of the heart. This prevent pulmonary embolism

6. Nerve Damage - this complication of I.V. infusion result from trying the arm too tightly to the splint

Assessment Numbness of fingers and hands

Nursing Intervention Massage the area and move shoulder through its ROM Instruct the patient to open and close hand several times each hour Physical therapy may be required Take note: apply splint with the fingers free to move

7. Speed Shock - This complication of I.V. infusion result from administration of I.V. push medication rapidly. To avoid speed shock and possible cardiac arrest, give most I.V. push medication over 3 to 5 mins.

OBJECTIVES OF BLOOD TRANSFUSION THERAPY

1. To increase circulating blood volume after surgery, trauma, or hemorrhage

2. To increase the number of RBC's and to maintain hemoglobin levels in clients with severe anemia

3. To provide selected cellular components as replacements therapy (e.g. clotting factors, platelets, albumin)

Nursing Interventions of Blood Transfusion Therapy (note: consent is needed)

1. Verify doctor's order. Inform the client and explain the purpose of the procedure

2. Check for cross matching and typing. To ensure compatibility

3. Obtain and record baseline vital signs

4. Practice strict asepsis

5. At least 2 licensed nurses check the label of the blood transfusion. Check the following:

Serial number Blood component Blood type

Rh factor Expiration date

Screening test (VDRL, HBsAg, malarial smear) - to ensure that the blood is free from blood-carried diseases and therefore, safe from transfusion 6. Warm blood at room temperature before transfusion to prevent chills 7. Identify client properly. Two nurses check the client's identification 8. Use needle gauge 18 to 19. This allow easy flow of blood 9. Use BT set with special micron mesh filter. To prevent administration of blood clots and particles 10. Start blood transfusion therapy slowly at 10 gtts/min. Remain at bedside for 15-30 mins. Adverse reaction usually occurs during the first 15 to 20 mins

11. Monitor vital signs. Altered vital signs indicate adverse reaction: Do not mix medication with blood transfusion. To prevent adverse effects Do not incorporate medication into the blood transfusion Do not use blood transfusion line for I.V. push of medication

12. Administer 0.9% NaCl before, during, or after Blood Transfusion Therapy. Never administer I.V. fluids with dextrose because it causes hemolysis

13. Administer Blood Transfusion Therapy for 4 hrs (whole blood, packed RBC). For plasma, platelets, cryoprecipitate, transfuse quickly (20 mins) clotting factor can easily destroyed.

COMPLICATIONS OF BLOOD TRANSFUSION

1 Allergic Reaction - this type of complication of blood transfusion is caused by sensitivity to plasma protein of donor antibody, which reacts with recipient antigen

Assessment:

Flushing Rush, hives Pruritus Laryngeal edema, difficulty of breathing 2. Febrile, Non-Hemolytic - this type of complication of blood transfusion is caused by hypersensitivity to donor white cells, platelets or plasma proteins. This is the most symptomatic complication of blood transfusion Assessment: Sudden chills and fever Flushing Headache Anxiety 3. Septic Reaction - this type of complication of blood transfusion is caused by the transfusion of blood or components contaminated with bacteria Assessment: Rapid onset of chills Vomiting Marked hypotension High fever

4. Circulatory Overload - this type of complication of blood transfusion is caused by administration of blood volume at rate greater than the circulatory system can accommodate

Assessment:

Rise in venous return Dyspnea Crackles or rales Distended neck vein Cough Elevated blood pressure 5. Hemolytic Reaction - this type of complication of blood transfusion is caused by infusion of incompatible blood products Assessment: Low back pain (first sign). This is due to inflammatory response of the kidneys to incompatible blood Chills Feeling of fullness Tachycardia Flushing Tachypnea Hypotension Bleeding Vascular collapse Acute renal failure NURSING INTERVENTIONS WHEN BLOOD TRANSFUSION COMPLICATIONS OCCUR 1. The first thing to do when complications in blood transfusion occurs is to STOP TRANSFUSION 2. Then start or open I.V. line (0.9%NaCl) 3. Place the client in fowler's position and administer oxygen therapy depending in the hospital protocol 4. Check vital signs as often as 5 mins 5. Notify the doctor immediately about the complications of blood transfusion 6. Carry out doctor’s order; prepare the emergency drugs like antihistamines, vasopressor, fluids as protocol 7. Obtain urine specimen and send to the laboratory to determine presence of hemoglobin as a result of RBC hemolysis 8. Blood container, tubing, attached label, and transfusion record are saved and returned to the laboratory for analysis.

V. ASEPSIS AND INFECTION CONTROL

Handwashing – is the single, most effective practice to prevent spread of microorganisms.

4 Elements of Handwashing

1. Water

2. Friction

3. Soap

4. Time

Body Defenses against Infection

- Normal flora

- Intact skin

- Saliva and mucus membrane

- Cilia of the upper respiratory tract infection

- Inflammatory process

- Immune response

ASEPSIS

1. Medical Asepsis

– Clean technique

- reduces number of pathogens

-GIT

- Handwashing removes microorganism

2. Surgical Asepsis

- Sterile technique

- make object free of all microorganisms

- Dressing, catheterization and Surgical procedures and Specimen collection

Sterile Technique Guidelines

1. Never turn your back on a sterile field

2. Avoid talking

3. Keep all sterile objects within view

4. Moisture will carry bacteria across/ through a cloth or paper barrier

5. Open all sterile packages away from the sterile field to prevent crossover and contamination

Principles and Practices of Surgical Asepsis

- All objects use in the sterile field must be sterile

- Sterile objects remain sterile when touched by another sterile object

- Sterile objects or fields which fall out of the range of vision or below one‟s waist are considered contaminated

- Sterile items become contaminated when they come in contact with microorganism transported through the air

- When sterile object/field comes in contact with another surface, it becomes contaminated

- The edges of the sterile field are considered unsterile

Standard Precaution

- To be used in all clients in the hospital

- To be used in the following situations:

a. contact with blood, body fluid, excretions and secretions

b. contact with non-intact skin

c. contact with mucous membrane

- wash hands after contact with blood, body fluids, secretions, excretions, or contaminated objects

- wear gloves when touching blood, body fluids, secretions, excretions or contaminated objects

- wear mask, goggles, or face shield if there is potential for splashes or sprays of blood, body fluids, secretions or excretions to prevent splashing into the eyes or mucous membranes

- Use biohazard bag for linens soiled with blood, body fluids, secretions, or excretions

- Place sharps or needles in puncture-resistant container

- do not recap, bend, or break needles

Airborne Precaution

Measles Varicella Tuberculosis - use private room (negative airflow room)

- close the door at all times

Use HEPA filters (High-Efficiency Particulate Air)

- Particulate respirator/mask for health care workers

- Surgical mask for patient during transport

- discard tissue wipes with sputum in plastic bags

Droplet Precautions

Pneumonia Meningitis Rubella Scarlet fever Diphtheria Pertussis - use surgical mask

Use disposable eating utensils

Contact Precautions

Herpes simplex Staphylococcal infection Hepatitis A Respiratory syncytial virus (RSV) Wound/skin infection Methicillin-resistant staphylococcal aureus (MRSA) Vancomycin-resistant enterocolitis (VRE) Rotavirus infection (most common cause of diarrhea in the U.S.) - use gloves, gown (if clothing comes in contact with patients, environmental surfaces, or items in the room, if patient has diarrhea, wound drainage, or GI surgery).

5. The nurse is caring for a client receiving patient-controlled analgesia (PCA) for pain management. Which statement about PCA is true?

A. the PCA pump can‟t' infuse opioids continuously

B. pain relief is initiated by the client as needed

C. no complications related to opioid delivery by the pump exist

D. the nurse prescribes the dosage of opioid for delivery dose of medication

ANSWERS AND RATIONALE

1. A - Rationale: standard precautions are based on the concepts that all body substances are potentially infectious. The nurse should wear gloves when contact with body substances is potential, not when in contact with intact skin. Mask should be used as a barrier to prevent transmission of droplet infections. Signs on door are unnecessary for standard precaution.

2. A - Rationale: hospices provide supportive, palliative care to terminally ill clients and their families

3. D - Rationale: documentation should be factual and accurate, what are heard, seen, smelled, or felt. Documentation of ulcer should include exact size and location. Interpretations, conclusions, opinions should not be documented.

4. C - Rationale: the nurse must put the medicines in the secured area. She should not leave the medications at the bedside. The nurse should not omit doses of medications without physician's order

5. B - Rationale: the client pushes a button to self-administer narcotic analgesic. The PCA pump also allows for continuous infusions of the medication. The client may still experience complications of the medication. It is the physician who prescribes the medication order
