Nurse Licensure Examination Review
The musculo-skeletal system consists of the muscles, tendons, bones and cartilage together with the joints
The primary function of which is to produce skeletal movements
Three types of muscles exist in the body 1. Skeletal Muscles
◦ Voluntary and striated 2. Cardiac muscles
◦ Involuntary and striated 3. Smooth/Visceral muscles
◦ Involuntary and NON-striated
Bands of fibrous connective tissue that tie bones to muscles
Strong, dense and flexible bands of fibrous tissue connecting bones to another bone
Variously classified according to shape, location and size
Functions1. Locomotion2. Protection3. Support and lever4. Blood production5. Mineral deposition
The part of the Skeleton where two or more bones are connected
A dense connective tissue that consists of fibers embedded in a strong gel-like substance
Sac containing fluid that are located around the joints to prevent friction
The nurse usually evaluates this small part of the over-all assessment and concentrates on the patient’s posture, body symmetry, gait and muscle and joint function
1. HISTORY 2. Physical Examination
◦ Perform a head to toe assessment◦ Nurses need to inspect and palpate ◦ The special procedure is the assessment of
joint and muscle movement◦ Usually, a tape measure and a protractor
are the only instruments
Gait Posture Muscular palpation Joint palpation Range of motion Muscle strength
LABORATORY PROCEDURES 1. BONE MARROW ASPIRATION
◦Usually involves aspiration of the marrow to diagnose diseases like leukemia, aplastic anemia
◦Usual site is the sternum and iliac crest◦Pre-test: Consent◦ Intratest: Needle puncture may be painful◦Post-test: maintain pressure dressing and
watch out for bleeding
LABORATORY PROCEDURES 2. Arthroscopy
◦ A direct visualization of the joint cavity◦ Pre-test: consent, explanation of
procedure, NPO◦ Intra-test: Sedative, Anesthesia, incision
will be made◦ Post-test: maintain dressing, ambulation
as soon as awake, mild soreness of joint for 2 days, joint rest for a few days, ice application to relieve discomfort
LABORATORY PROCEDURES3. BONE SCAN Imaging study with the use of a contrast
radioactive material Pre-test: Painless procedure, IV
radioisotope is used, no special preparation, pregnancy is contraindicated
Intra-test: IV injection, Waiting period of 2 hours before X-ray, Fluids allowed, Supine position for scanning
Post-test: Increase fluid intake to flush out radioactive material
LABORATORY PROCEDURES4. DXA- Dual-energy XRAY absorptiometry
Assesses bone density to diagnose osteoporosis
Uses LOW dose radiation to measure bone density
Painless procedure, non-invasive, no special preparation
Advise to remove jewelry
The Nursing Management
PAIN These can be related to joint
inflammation, traction, surgical intervention
1. Assess patient’s perception of pain 2. Instruct patient alternative pain
management like meditation, heat and cold application, TENS and guided imagery
PAIN 3. Administer analgesics as prescribed
◦ Usually NSAIDS◦ Meperidine can be given for severe pain
4. Assess the effectiveness of pain measures
IMPAIRED PHYSICAL MOBILITY 1. Instruct patient to perform range of
motion exercises, either passive or active 2. Provide support in ambulation with
assistive devices 3. Turn and change position every 2 hours 4. Encourage mobility for a short period
and provide positive reinforcements for small accomplishments
SELF-CARE DEFICITS 1. Assess functional levels of the patient 2. Provide support for feeding problems
◦ Place patient in Fowler’s position◦ Provide assistive device and supervise mealtime◦ Offer finger foods that can be handled by patient◦ Keep suction equipment ready
SELF-CARE DEFICITS 3. Assist patient with difficulty bathing and
hygiene◦ Assist with bath only when patient has difficulty◦ Provide ample time for patient to finish activity
TractionCast
Traction A method of fracture immobilization by
applying equipments to align bone fragments
Used for immobilization, bone alignment and relief of muscle spasm
Skin traction
Skeletal traction
Pulling force exerted on bones to reduce or immobilize fractures, reduce muscle spasm, correct or prevent deformities
Traction: General principles 1. ALWAYS ensure that the weights
hang freely and do not touch the floor 2. NEVER remove the weights 3. Maintain proper body alignment 4. Ensure that the pulleys and ropes are
properly functioning and fastened by tying square knot
Traction: General principles 5. Observe and prevent foot drop
◦ Provide foot plate 6. Observe for DVT, skin irritation and
breakdown 7. Provide pin care for clients in skeletal
traction- use of hydrogen peroxide
CAST Immobilizing tool made of plaster of Paris or
fiberglass Provides immobilization of the fracture
CAST: types1. Long arm2. Short arm3. Spica
Plaster of Paris◦ Drying takes 1-3 days◦ If dry, it is SHINY, WHITE, hard and resistant
Fiberglass◦ Lightweight and dries in 20-30 minutes◦ Water resistant
CAST: General Nursing Care 1. Allow the cast to dry (usually 24-
72 hours) 2. Handle a wet cast with the
PALMS not the fingertips 3. Keep the casted extremity
ELEVATED using a pillow 4. Turn the extremity for equal
drying. DO NOT USE DRYER for plaster cast
CAST: General Nursing Care5. Petal the edges of the cast to prevent crumbling of the edges
6. Examine the skin for pressure areas and Regularly check the pulses and skin
CAST: General Nursing Care7. Instruct the patient not to place sticks or small objects inside the cast
8. Monitor for the following: pain, swelling, discoloration, coolness, tingling or lack of sensation and diminished pulses
Nursing management
Osteoporosis A disease of the bone characterized by a
decrease in the bone mass and density with a change in bone structure
Osteoporosis: Pathophysiology Normal homeostatic bone turnover is
altered rate of bone RESORPTION is greater than bone FORMATION reduction in total bone mass reduction in bone mineral density prone to FRACTURE
Osteoporosis: TYPES 1. Primary Osteoporosis- advanced age,
post-menopausal 2. Secondary osteoporosis- Steroid
overuse, Renal failure
RISK factors for the development of Osteoporosis
1. Sedentary lifestyle 2. Age 3. Diet- caffeine, alcohol, low Ca and Vit D 4. Post-menopausal 5. Genetics- caucasian and asian 6. Immobility
ASSESSMENT FINDINGS 1. Low stature 2. Fracture
◦ Femur 3. Bone pain
LABORATORY FINDINGS 1. DEXA-scan
◦ Provides information about bone mineral density◦ T-score is at least 2.5 SD below the young adult
mean value 2. X-ray studies
Medical management of Osteoporosis 1. Diet therapy with calcium and Vitamin D 2. Hormone replacement therapy 3. Biphosphonates- Alendronate,
risedronate produce increased bone mass by inhibiting the OSTEOCLAST
4. Moderate weight bearing exercises 5. Management of fractures
Osteoporosis Nursing Interventions1. Promote understanding of osteoporosis
and the treatment regimen Provide adequate dietary supplement of
calcium and vitamin D Instruct to employ a regular program of
moderate exercises and physical activity Manage the constipating side-effect of
calcium supplements
Osteoporosis Nursing Interventions Take calcium supplements with meals Take alendronate with an EMPTY stomach
with water Instruct on intake of Hormonal replacement
Osteoporosis Nursing Interventions2. Relieve the pain
Instruct the patient to rest on a firm mattress
Suggest that knee flexion will cause relaxation of back muscles
Heat application may provide comfort Encourage good posture and body
mechanics Instruct to avoid twisting and heavy
lifting
Osteoporosis Nursing Interventions 3. Improve bowel elimination Constipation is a problem of calcium
supplements and immobility Advise intake of HIGH fiber diet and
increased fluids
Osteoporosis Nursing Interventions 4. Prevent injury Instruct to use isometric exercise to
strengthen the trunk muscles AVOID sudden jarring, bending and
strenuous lifting Provide a safe environment

OSTEOARTHRITIS The most common form of degenerative
joint disorder
OSTEOARTHRITIS Chronic, NON-systemic disorder of joints
OSTEOARTHRITIS: Pathophysiology Injury, genetic, Previous joint
damage, Obesity, Advanced age Stimulate the chondrocytes to release chemicals chemicals will cause cartilage degeneration, reactive inflammation of the synovial lining and bone stiffening
OSTEOARTHRITIS: Risk factors 1. Increased age 2. Obesity 3. Repetitive use of joints with previous joint
damage 4. Anatomical deformity 5. genetic susceptibility
OSTEOARTHRITIS: Assessment findings 1. Joint pain 2. Joint stiffness 3. Functional joint impairment
limitation The joint involvement is ASYMMETRICAL This is not systemic, there is no FEVER,
no severe swelling Atrophy of unused muscles Usual joint are the WEIGHT bearing joints
OSTEOARTHRITIS: Assessment findings1. Joint pain Caused by
◦ Inflamed synovium◦ Stretching of the joint capsule◦ Irritation of nerve endings
OSTEOARTHRITIS: Assessment findings2. Stiffness commonly occurs in the morning after commonly occurs in the morning after
awakeningawakening Lasts only for less than 30 minutes DECREASES with movementCrepitation may be elicited
OSTEOARTHRITIS: Diagnostic findings1. X-ray Narrowing of joint space Loss of cartilage Osteophytes2. Blood tests will show no evidenceno evidence of
systemic inflammation and are not useful
OSTEOARTHRITIS: Medical management 1. Weight reduction 2. Use of splinting devices to support
joints 3. Occupational and physical therapy 4. Pharmacologic management

may be used in the early acute stage!!!◦ Plan daily activities when pain is less
severe◦ Pain meds before exercising
OSTEOARTHRITIS: Nursing Interventions 2. Advise patient to reduce weight
◦ Aerobic exercise◦ Walking
3. Administer prescribed medications◦ NSAIDS
A type of chronic systemic inflammatory arthritis and connective tissue disorder affecting more women (ages 35-45) than men
FACTORS:GeneticAuto-immune connective tissue disordersFatigue, emotional stress, cold, infection
Pathophysiology Immune reaction in the synovium
attracts neutrophils releases enzymes breakdown of collagen irritates the synovial liningcausing synovial inflammation edema and pannus formation and joint erosions and swelling
ASSESSMENT FINDINGS 1. PAIN 2. Joint swelling and stiffness-SYMMETRICAL, Bilateral
3. Warmth, erythema and lack of function
4. Fever, weight loss, anemia, fatigue 5. Palpation of join reveals spongy tissue 6. Hesitancy in joint movement
ASSESSMENT FINDINGS Joint involvement is SYMMETRICAL and
BILATERAL Characteristically beginning in the hands,
wrist and feet Joint STIFFNESS occurs early morning,
lasts MORE than 30 minutes, not relieved by movement, diminishes as the day progresses
ASSESSMENT FINDINGS Joints are swollen and warm Painful when moved Deformities are common in the hands
and feet causing misalignment Rheumatoid nodules may be found in
the subcutaneous tissues
Diagnostic test 1. X-ray
◦ Shows bony erosion 2. Blood studies reveal (+)
rheumatoid factor, elevated ESR and CRP and ANTI-nuclear antibody
3. Arthrocentesis shows synovial fluid that is cloudy, milky or dark yellow containing numerous WBC and inflammatory proteins
MEDICAL MANAGEMENT 1. Therapeutic dose of NSAIDS and
Aspirin to reduce inflammation 2. Chemotherapy with methotrexate,
antimalarials, gold therapy and steroid 3. For advanced cases- arthroplasty,
synovectomy 4. Nutritional therapy
MEDICAL MANAGEMENTGOLD THERAPY: IM or Oral preparation Takes several months (3-6) before
effects can be seen Can damage the kidney and causes bone
marrow depression
Nursing MANAGEMENT1. Relieve pain and discomfort USE splints to immobilize the
affected extremity during acute stage of the disease and inflammation to REDUCE DEFORMITY
Administer prescribed medications Suggest application of COLD packs
during the acute phase of pain, then HEAT application as the inflammation subsides
Nursing MANAGEMENT2. Decrease patient fatigueSchedule activity when pain is less severe
Provide adequate periods of rests
3. Promote restorative sleep
Nursing Management4. Increase patient mobilityAdvise proper posture and body mechanics
Support joint in functional position
Advise ACTIVE ROME
Nursing Management5. Provide Diet therapyPatients experience anorexia, nausea and weight loss
Regular diet with caloric restrictions because steroids may increase appetite
Supplements of vitamins, iron and PROTEIN
6. Increase Mobility and prevent deformity:
Lie FLAT on a firm mattressLie PRONE several times to prevent HIP FLEXION contracture
Use one pillow under the head because of risk of dorsal kyphosis
NO Pillow under the joints because this promotes flexion contractures
HOT Cold
Use to RELIEVE joint stiffness, pain and muscle spasm
Use to control inflammation and pain
After acute attack ACUTE ATTACK
A systemic disease caused by deposition of uric acid crystals in the joint and body tissues
CAUSES: 1. Primary gout- disorder of Purine
metabolism 2. Secondary gout- excessive uric
acid in the blood like leukemia
ASSESSMENT FINDINGS 1. Severe pain in the involved joints,
initially the big toe 2. Swelling and inflammation of the joint 3. TOPHI- yellowish-whitish,
irregular deposits in the skin that break open and reveal a gritty appearance
4. PODAGRA
ASSESSMENT FINDINGS 5. Fever, malaise 6. Body weakness and headache 7. Renal stones
DIAGNOSTIC TEST Elevated levels of uric acid in the blood Uric acid stones in the kidney
Medical management 1. Allupurinol- take it WITH FOOD
Rash signifies allergic reaction
2. Colchicine For acute attack
Nursing Intervention1. Provide a diet with LOW purine Avoid Organ meats, aged and processed
foods STRICT dietary restriction is NOT
necessary2. Encourage an increased fluid intake (2-
3L/day) to prevent stone formation3. Instruct the patient to avoid alcohol4. Provide alkaline ash diet to increase
urinary pH5. Provide bed rest during early attack of gout
Nursing Intervention6. Position the affected extremity in mild
flexion7. Administer anti-gout medication and
analgesics
A break in the continuity of the bone and is defined according to its type and extent
Severe mechanical Stress to bone bone fracture
Direct Blows Crushing forces Sudden twisting motion Extreme muscle contraction
TYPES OF FRACTURE 1. Complete fracture
◦ Involves a break across the entire cross-section 2. Incomplete fracture
◦ The break occurs through only a part of the cross-section
TYPES OF FRACTURE 1. Closed fracture
◦ The fracture that does not cause a break in the skin
2. Open fracture◦ The fracture that involves a break in the skin
TYPES OF FRACTURE 1. Comminuted fracture
◦ A fracture that involves production of several bone fragments
2. Simple fracture◦ A fracture that involves break of bone into two
parts or one
ASSESSMENT FINDINGS 1. Pain or tenderness over the involved
area 2. Loss of function 3. Deformity 4. Shortening 5. Crepitus 6. Swelling and discoloration
ASSESSMENT FINDINGS1. Pain Continuous and increases in severity Muscles spasm accompanies the fracture is
a reaction of the body to immobilize the fractured bone
ASSESSMENT FINDINGS2. Loss of function Abnormal movement and pain can result to
this manifestation
ASSESSMENT FINDINGS3. Deformity Displacement, angulations or rotation of the
fragments Causes deformity
ASSESSMENT FINDINGS4. Crepitus A grating sensation produced when the
bone fragments rub each other
DIAGNOSTIC TEST X-ray
EMERGENCY MANAGEMENT OF FRACTURE 1. Immobilize any suspected fracture 2. Support the extremity above and
below when moving the affected part from a vehicle
3. Suggested temporary splints- hard board, stick, rolled sheets
4. Apply sling if forearm fracture is suspected or the suspected fractured arm maybe bandaged to the chest
EMERGENCY MANAGEMENT OF FRACTURE 5. Open fracture is managed by covering a
clean/sterile gauze to prevent contamination
6. DO NOT attempt to reduce the facture
MEDICAL MANAGEMENT 1. Reduction of fracture either open or
closed, Immobilization and Restoration of function
2. Antibiotics, Muscle relaxants and Pain medications
General Nursing MANAGEMENT For CLOSED FRACTURE 1. Assist in reduction and immobilization 2. Administer pain medication and muscle
relaxants 3. teach patient to care for the cast 4. Teach patient about potential
complication of fracture and to report infection, poor alignment and continuous pain
General Nursing MANAGEMENT For OPEN FRACTURE 1. Prevent wound and bone infection Administer prescribed antibiotics Administer tetanus prophylaxis Assist in serial wound debridement 2. Elevate the extremity to prevent edema
formation 3. Administer care of traction and cast
FRACTURE COMPLICATIONS Early 1. Shock 2. Fat embolism 3. Compartment syndrome 4. Infection 5. DVT
FRACTURE COMPLICATIONS Late 1. Delayed union 2. Avascular necrosis 3. Delayed reaction to fixation devices 4. Complex regional syndrome
FRACTURE COMPLICATIONS: Fat Embolism Occurs usually in fractures of the long
bones Fat globules may move into the blood
stream because the marrow pressure is greater than capillary pressure
Fat globules occlude the small blood vessels of the lungs, brain kidneys and other organs
FRACTURE COMPLICATIONS: Fat Embolism Onset is rapid, within 24-72 hours ASSESSMENT FINDINGS 1. Sudden dyspnea and respiratory
distress 2. tachycardia 3. Chest pain 4. Crackles, wheezes and cough 5. Petechial rashes over the chest, axilla
and hard palate

cause of death Administer O2 in high concentration Prepare for possible intubation and
ventilator support
FRACTURE COMPLICATIONS: Fat Embolism Nursing Management 2. Administer drugs Corticosteroids Dopamine Morphine
FRACTURE COMPLICATIONS: Fat Embolism Nursing Management 3. Institute preventive measures Immediate immobilization of fracture Minimal fracture manipulation Adequate support for fractured bone
during turning and positioning Maintain adequate hydration and
electrolyte balance
Early complication: Compartment syndrome
A complication that develops when tissue perfusion in the muscles is less than required for tissue viability
Early complication: Compartment syndrome ASSESSMENT FINDINGS 1. Pain- Deep, throbbing and UNRELIEVED
pain by opiods Pain is due to reduction in the size of the
muscle compartment by tight cast Pain is due to increased mass in the
compartment by edema, swelling or hemorrhage
