Nursing of Adult Patientswith
Medical & Surgical Conditions
Musculoskeletal
Disorders
Assessment Scoliosis
• Lateral curvature of the spine
Assessment Kyphosis
• A rounding of the thoracic spine• Hump-backed appearance
Assessment Loradosis
• An increase in the curve at the lumbar region
Assessment
Blanching Test• Capillary nail refill• Signals circulation status• Compress each fingernail or toenail, release the
pressure, and note how quickly the pink color returns to the nail bed.
• Should return to normal color within 2 seconds
Diagnostic Tests Myelogram
• Injection of a radiopaque dye into the subarachnoid space at the lumbar spine to determine the presence of herniated disk or tumors.
• Assess for allergies to iodine and seafood
• Oil-based dye• Removed to prevent meningeal irritation
• Flat for 12 hours (keeps air space in lower spine)
• Water-soluble dye• Not removed; absorbed by body
• Semi-fowler’s position for 8 hours (keeps dye in lower spine)
• Encourage fluids to assist with absorption of dye
Diagnostic Tests
Nuclear Scanning• Given a low dosage of radioactive isotopes• Scanner or camera detector is used to record
images• Nursing Measures
• Written consent
• Informing the patient about radioacive isotopes; will not affect others
• Follow instrucitions by nuclear medicine dept.
Diagnostic Tests
Magnetic Resonance Imaging• Involves the use of magnetism and radio waves
to make images of cross sections of the body• Gives detailed picture of fluid filled soft tissue
and blood vessels• Patient must remove any metal objects
• patients with metal prosthesis (heart valves, othopedic screws) cannot undergo and MRI
• Sedatives may be given for anxiety due to claustrophobia
Diagnostic Tests Computer Axial Tomography (CAT scan)
• 3-D picture of the structure (Soft tissue & bones)• More sensitive than standard x-rays• Iodine contrast may be used• Nursing Measures
• Written consent
• Ask about allergies to iodine and seafood
• NPO 3-4 hours before test
• Baseline vital signs
• Remove jewelry, etc.
• Teach pt. about procedure
Computer Axial Tomography (CAT scan)
Diagnostic Tests
Bone Scan• Detects metastatic and inflammatory bone disease• Radioisotopes administered IV 2-3 hours before
test• Encourage fluids• A scanning camera is used to reveal the degree of
uptake• Areas of uptake may indicate a tumor or other
abnormality
Diagnostic Tests
Arthroscopy• Direct visualization of a joint
• exploration of joint• drainage of fluid from the joint• removal of damaged tissue or foreign bodies
• Involves insertion of a large-bore needle into the suprapatellar pouch.
• Patient may be given a general or local anesthetic • Activities may be limited for several days
Diagnostic Tests Synovial Fluid Aspiration
• The puncture of a joint with a needle and the withdrawal of synovial fluid
• Used for diagnosis of trauma, systemic lupus, gout, osteoarthritis, and rheumatoid arthritis
• Normally straw colored, clear, or slightly cloudy• After procedure
• support extremity
• joint rest for 12 hours
• ice to joint for 24 - 48 hours
• assess for s/s of infection
Diagnostic Tests
Electromyogram (EMG)• Insertion of needle electrodes into the skeletal
muscles to record the electrical activity• Muscles do not produce electrical charge at rest• Unusual patterns may be observed for
neuropathy and myopathy
Rheumatoid Arthritis Etiology/Pathophysiology
• Most serious form of arthritis• Chronic, systemic disease• Most common in women of childbearing age• Autoimmune disorder, but may also be genetic• Agents that should protect the body attack joint
tissues• Can affect lungs, heart, blood vessels, muscles, eyes
and skin• Chronic inflammation of the synovial membrane of
the diarthrodial joints (movable)
Rheumatoid Arthritis
Signs & Symptoms• Characterized by periods of remission and
exacerbation• Malaise• Muscle weakness• Loss of appetite• Generalized aching• Edema & tenderness of joints• Limited range of motion (morning stiffness)
Rheumatoid Arthritis
Rheumatoid Arthritis
Diagnostic Tests• Radiography studies show loss of articular cartilage
and change in bone structure
• Laboratory Tests• Erythrocyte Sedimentation Rate (ESR)
– increase indicates inflammation
• Rheumatoid Factor (RF)– elevation indicates abnormal serum protein concentration
• Latex agglutination test– detects presence of IgM version of rheumatoid factor (anti-IgG
antibodies)
• Synovial fluid aspiration– fluid is cloudy, yellow, less viscous and increased protein
Rheumatoid Arthritis Treatment
• Medications• Salicylates (Aspirin)
• Nonsteroidal Anitinflammatory Drugs (NSAID’s)– indomethacin (Indocin)– ibuprofen (Motrin)– naproxen (Naprosyn)– piroxicam (Feldene)– nabumetone (Relafen)
• Potent Antiinflammatory Agents– adrenocorticosteroids (prdnisone)– phenylbutazone (Butazolidin)
• Slow-Acting Antiinflammatory Agents (6-12 mo.)– hydroxychloroquine (Plaquenil)
Rheumatoid Arthritis
• Rest• 8-10 hours of sleep a night; 2 hour nap during day
• Exercise• Range of motion 2-3 times per day
• prevents joints from “freezing” and muscles from weakening
• Heat• Hot packs, heat lamp, and/or hot paraffin
• Relaxes and soothes muscles
• Rehabilitation• Help pt. to adapt to physical limitaions and promoting
normal daily activities
Rheumatoid Arthritis
Prognosis• Remissions and exacerbations are common• Disease normally progresses to include joint
deformity, extensive muscle atrophy, soft tissue lesions, bone and cartilage destruction, and fibrous or bony ankylosis (fixed joints)
Ankylosing Spondylitis
Etiology/Pathophysiology• Chronic, progressive disorder of the sacroiliac
and hip joints, the synovial joints of the spine, and the adjacent soft tissues.
• Most common in young men• Strong hereditary tendency
Ankylosing Spondylitis
Signs & Symptoms• Low back pain and stiffness
• “sciatica pain” lasts for a few days then subsides• worse when standing
• May also affect joints in the neck, jaw, shoulders, knees, and hips

Ankylosing Spondylitis
Ankylosing Spondylitis
Diagnostic Tests• Hemoglobin and Hematocrit

permanent destruction of affected cartilage and underlying bone.
Gout (Gouty Arthritis) Etiology/Pathophysiology
• Metabolic disease resulting from an accumulation of uric acid in the blood
• Caused by an ineffective metabolism of purines• Primary
• hereditary factors
• Secondary• use of certain drugs, complication of other diseases, or
idiopathic
• Affects men more frequently than women• Does not occur before puberty in the male or before
menopause in the female
