The Beginning of Medical The Beginning of Medical LanguageLanguage

• Etymology is the study of word origins.• Many words have come from other

languages.• Many medical words come from the

ancient Latin or Greek languages.

• Some medical words are identical to Latin or Greek words.

• Some medical words are similar (but not identical) to Latin or Greek words.

• Some medical words are similar to words from old English, Dutch, and French.

Medical Word PartsMedical Word Parts

• Medical language contains medical words.

• Most medical words contain word parts.• Word parts are puzzle pieces that, when

fit together, build a medical word.

1-4



Medical Word PartsMedical Word Parts

There are three different kinds of word parts.

Word Part Meaning

combining form the foundation of the word

suffix the word ending

prefix an optional word beginning

• Follow these simple directions for pronouncing medical words: Say each syllable by following the “see-

and-say” pronunciation. Accented syllables are in all capital

letters.

1-7




• Follow these simple directions for pronouncing medical words: Secondary accented syllables are in

smaller capital letters. Practice pronouncing the word several

times until you have mastered its pronunciation.

The Medical RecordThe Medical Record

• The medical record is where healthcare professionals document all care provided to a patient.

• It contains not only medical documents, but those that are also legal documents that can be used in a court of law.

1-8




• The paper medical record has been the traditional form of a medical record, but it has some disadvantages: Only one person can access it at a time. It can become lost or damaged, and it

can take time to retrieve a patient's past medical records.• This delay can compromise the delivery

of quality care.

1-8



Computerized PatientComputerized PatientRecords (CPRs)Records (CPRs)

• Most physicians' offices, hospitals, and other healthcare facilities have converted to computerized patient records (CPRs).

• Healthcare professionals can have immediate access to both current and previous medical records.

• Consent to Treatment Forms Before patients can be treated at any

type of healthcare facility, they must sign consent to treatment forms that give the physicians and other healthcare professionals the right to treat them.• Treatment without consent is against the

law and is considered to be battery (touching another person without his or her consent).

1-8




• Consent to Treatment Forms For patients who are minors, the parent

or legal guardian signs the consent to treatment.• In an emergency situation, care is

provided until the appropriate person is able to consent.

Figure 2-1 Human body in anatomical position.

2-1



Body Planes Body Planes and Body Directionsand Body Directions

• When the human body is in anatomical position, it can be studied by dividing it with planes.

• A plane is an imaginary flat surface, like a plate of glass, that divides the body into two parts.

• There are three body planes: coronal plane, sagittal plane, and transverse plane.

2-1



Body Planes Body Planes and Body Directionsand Body Directions

• These body planes divide the body into front and back, right and left, and top and bottom sections.

• Body directions represent movement away from or toward those planes.

2-1



Coronal Plane and Body DirectionsCoronal Plane and Body Directions

• The coronal plane (or frontal plane) is a vertical plane that divides the body into front and back sections.

• The coronal plane is named for the coronal suture in the cranium.

2-1



Figure 2-2 Coronal plane.

• The front of the body is the anterior or ventral section.

• The back of the body is the posterior or dorsal section.

2-1




• Lying with the anterior section of the body down is being in the prone position.

• Lying with the posterior section of the body down is being in the dorsal or supine position.

Sagittal Plane and Body DirectionsSagittal Plane and Body Directions

• The sagittal plane is a vertical plane that divides the body into right and left sections.

• The sagittal plane is named for the sagittal suture in the cranium.

2-1




• If this plane divides the body at the midline into equal right and left sections, then it is a midsagittal plane.

2-1




• Moving from the side of the body toward the midline is moving in a medial direction, or medially.

• Moving from the midline toward the side of the body is moving in a lateral direction, or laterally.

• Bilateral indicates both sides.

Body CavitiesBody Cavities

• The human body can be studied according to its body cavities and their internal organs.

• A cavity is a hollow space that is surrounded by bones or muscles.

• The cranial cavity lies within and is protected by the cranium.

2-2




• The spinal cavity or spinal canal is a continuation of the cranial cavity as it travels down the midline of the back.

• The spinal cavity lies within and is protected by the bones (vertebrae) of the spine.

• The spinal cavity contains the spinal cord, the spinal nerves, and spinal fluid.

2-2




• The thoracic cavity lies within the chest and is protected by the breast bone (sternum) anteriorly, the ribs bilaterally, and the bones of the spine posteriorly.

2-2




• The inferior border of the thoracic cavity is the large, muscular diaphragm that functions during respiration.

• The thoracic cavity contains the lungs.

2-2




• The abdominal cavity lies within the abdomen and is protected by the abdominal wall anteriorly, and the bones of the spine posteriorly.

• The pelvic cavity is a continuation of the abdominal cavity and is surrounded by the pelvic (hip) bones anteriorly and bilaterally, and the bones of the spine posteriorly.

2-2




• These two cavities are often called the abdominopelvic cavity because it is one continuous cavity with no dividing structure.

The Body in DiseaseThe Body in Disease

• Preventive medicine is the healthcare specialty that focuses on keeping a person healthy and preventing disease.

• Much of medical language deals with diseases and how they are diagnosed and treated.

• Disease is any change in the normal structure or function of the body.

2-3



The Body in DiseaseThe Body in Disease

• The etiology is the cause or origin of a disease.

• In most cases, the cause of a disease is known or can be discovered through medical testing. In some cases, the exact cause of a disease is never completely understood.

2-3



Disease CategoriesDisease Categories

• Congenital• Degenerative• Environmental• Hereditary• Iatrogenic

• Idiopathic• Infectious• Neoplastic• Nosocomial• Nutritional

2-3



Onset of DiseaseOnset of Disease

• The onset of disease is often noticed because of symptoms and/or signs.

• A symptom is any deviation from health that is experienced or felt by the patient.

• When a symptom can be seen or detected by others, it is known as a sign.

2-3




• Symptomatology is the clinical picture of all the patient's symptoms and signs.

• A syndrome is a set of symptoms and signs associated with, and characteristic of, one particular disease.

2-3




• Patients who are asymptomatic (showing no symptoms or signs) can still have a disease, but one that can only be detected by medical tests.

2-3




• The physician takes a history and performs a physical examination.

• For the history of the present illness, the physician asks the patient in detail about the location, onset, duration, and severity of the symptoms.

2-4




• The physician also asks about the patient's past medical history, past surgical history, family history, social history, and history of allergies to drugs.

• After taking the patient's history, the physician performs a physical examination to look for signs of disease.

2-4




• The physician uses the following techniques (as needed) during the physical examination: inspection, palpation, auscultation, and percussion.

• Based on the patient's history and results of the physical examination, the physician makes a diagnosis and identifies the nature and cause of the disease or condition.

2-4




• If the physician cannot make a final diagnosis, a temporary or working diagnosis is assigned and the patient is scheduled to undergo further diagnostic tests or referred to a specialist.

2-4



Course and Outcome of DiseaseCourse and Outcome of Disease

• The course of a disease includes all events from the onset of the disease until its final outcome.

• Symptoms and signs may be: Acute (sudden in nature and severe in

intensity), Subacute (less severe in intensity), or Chronic (continuing for three months or

more)

2-3




• An exacerbation is a sudden worsening in the severity of the symptoms or signs.

• Remission is a temporary improvement in the symptoms and signs of a disease without the underlying disease being cured.

2-3




• A relapse or recurrence is a return of the original symptoms and signs of the disease.

• A sequela is an abnormal condition or complication that arises because of the original disease and remains after the original disease has resolved.

2-3




• The physician prescribes drugs or orders therapy for the patient.

• If the treatment is therapeutic, the symptoms or signs of the disease disappear.

2-3




• A disease that is refractory (resistant) is one that does not respond to treatment.

• Certain diseases that cannot be treated with drugs or therapy may require surgery.

• The prognosis is the predicted outcome of the disease.

2-3




• The prognosis is the predicted outcome of a disease.

• The course of a disease ends in one of the following outcomes: Recuperation or recovery Disability Terminal illness

Healthcare ProfessionalsHealthcare Professionals

• Physician (or doctor) The leader of the healthcare team who

examines the patient, orders tests, diagnoses diseases, and treats diseases by prescribing drugs or therapy.

Surgeons are physicians who complete additional training in surgical techniques.

2-5




• Physician (or doctor) Primary care physicians (PCPs)

specialize in family practice or pediatrics.

A physician or doctor who is on the medical staff of a hospital and admits a patient to the hospital is known as the attending physician.

2-5




• Physician Extenders Healthcare professionals who work

under the supervision of a physician or doctor (MD or DO) to examine, diagnose, and treat patients and sometimes prescribe medications.

2-5




• Physician Extenders Examples include: • physician's assistants (PAs). • nurse practitioners (NPs). • certified nurse midwives (CNMs). • certified registered nurse anesthetists

(CRNAs).

2-5




• Allied Health Professionals Nurses (registered nurse [RN], licensed

practical nurse [LPN], or licensed vocational nurse [LVN]) examines patients, makes nursing diagnoses, and administers treatments or drugs ordered by the physician.

Nurses give hands-on care and focus on the physical and emotional needs of the patient and the family.

2-5




• Other Allied Health Professionals Technologists Technicians Therapists Dietitians Medical assistants Phlebotomists Dental hygienists Audiologists

2-5



Healthcare SettingsHealthcare Settings

• Hospital Traditional setting for providing care for

patients who are acutely ill and require medical or surgical care for longer than 24 hours.

The attending physician must write an order in the patient's medical record to admit or discharge the patient.

A patient in the hospital is an inpatient.

2-5




• Hospital Divided into floors or nursing units that

provide care for specific types of patients. There are also specialty care units such as the intensive care unit (ICU).

2-5




• Hospital Ancillary departments provide additional

types of services and include radiology, physical therapy (PT), dietary, emergency (ED or ER), clinical laboratory, and pharmacy.

2-5




• Physician's Office One of the most frequently used

healthcare settings A single physician (or group of

physicians) maintains an office where patients are seen, diagnosed, treated, and counseled.

2-5




• Physician's Office Some offices have their own laboratory

and x-ray equipment for performing diagnostic tests.

Seriously ill patients who cannot be quickly diagnosed or adequately treated in the office are sent to a hospital.

2-5




• Clinic Provides healthcare services similar to

that of a physician's office, but for just one type of patient or one type of disease

For example, a well-baby clinic provides care to newborn infants.

2-5




• Clinic Outpatient clinics are located in a

hospital or in their own separate facility and their patients are outpatients because they are not admitted to the hospital and do not stay overnight in the clinic.

2-5




• Ambulatory Surgery Center (ASC) A facility where minor surgery is

performed and the patient does not stay overnight.

2-5




• Long-Term Care Facility Primarily a residential facility for older

adults or those with disabilities who are unable to care for themselves

Provides 24-hour nursing care Persons in long-term care facilities are

called residents rather than patients because the facility is their home.

2-5




• Long-Term Care Facility Skilled nursing facility (SNF) is a long-

term care facility that provides a high level of medical and nursing care for patients recently discharged from the hospital.

2-5




• Home Health Agency Provides a range of healthcare services

to persons (who are known as clients) in their homes when they are unable to come to a physician's office or clinic and do not want to live in a long-term care facility.
