Musculoskeletal System Flashcards
A _____ is where two or more bones come together to allow for movement
Joint
Examples of synovial joints
Shoulder, knee
__________ attach muscles to bones
Tendons
_________ attach bones to bones
Ligaments
Minerals and hormones essential for bone growth/health
Calcium, vitamin D, phosphorous, PTH, calcitonin, growth hormone
Parathyroid hormone (PTH) pulls calcium out of the bones and into the bloodstream which _________ calcium levels
Increases
_________ is a hormone that counteracts the activity of PTH by inhibiting osteoclast activity and decreases reabsorption of calcium at the kidneys which decreases blood calcium levels
Calcitonin
Aspiration of synovial fluid from joint cavity
Arthrocentesis
Insertion of narrow tube with camera to visualize internal structure of joint and allows for collection of biopsies
Arthroscopy
Knee arthroscopy nursing consideration
Patient needs to be able to bend their knee at least 40 degrees and there cannot be an active infection in that knee
Procedure that uses low levels of X-rays to measure a patients bone mass for the diagnosis of osteoporosis
Dual x-ray absorptiometry (DXA)
Diagnostic used to identify fractures, bone cancer, and bone infections
Nuclear scans
Describe nuclear scan process
Administration of radioactive substance or isotope is administered 4-6 hrs before the procedure; nuclear scan will show a hot spot of where radiation has gathered revealing affected site; nuclear scans can be repeated at 24, 48, and 72 hours
Diagnostic used to evaluate muscle weakness by which needles are inserted into muscles and muscle activity is recorded
Electromyograpy (EMG)
Progressive degeneration of the articulate cartilage in a joint causing inflammation, development of bone spurs, and decreased mobility
Osteoarthritis
Osteoarthritis risk factors
Older age, female gender, smoking, obesity, repetitive stress on joints
S/S of osteoarthritis
Joint pain and stiffness, enlarged joints, crepitus, heberden’s nodes (higher up on finger) and bouchard’s nodes (lower on finger closer to body)
Osteoarthritis treatment
NSAIDs, topical medications such as voltaren gel (topical nsaid), topical capsaicin, glucosamine supplement (decreases inflammation and further degeneration of articulation cartilage), injections into synovial joint (corticosteroids, hyaluronic acid)
Osteoarthritis patient education
Balance rest with activity, weight loss if applicable, encourage strength training and physical therapy, yoga and tai chi are good exercises for osteoarthritis, apply ice for ACUTE exacerbations and heat for stiffness, use of splinting and assistive devices
Autoimmune disorder in which antibodies attack synovium leading to swelling, inflammation, and destruction of articulated cartilage and bone
Rheumatoid arthritis (RA)
T or F: rheumatoid arthritis is characterized by periods of exacerbation and remission
True
RA risk factors
Females, ages 20-50, family hx
S/S of RA
Bilateral and symmetrical joint pain and swelling, morning stiffness, ankylosis (joint fixation and deformity), swan neck and boutinniere deformities; swan neck is characterized by flexion of the distal interphalangeal joint and hyperextension of the proximal interphalangeal joint. The boutinniere deformity causes hyperextension of the distal joint and flexion of the proximal joint. Ulnar shift is occurs when all fingers start to bend towards pinky finger; subcutaneous nodules; fever, red sclera, lymphadenopathy (swelling of lymph nodes)
Abnormal labs with RA
Positive rheumatoid factor, positive ANA titer, elevated WBCs, CRP, and ESR
RA treatment
Immunosuppressants (prednisone, methotrexate), NSAIDs, hydroxychloroquine, Plasmapharesis, PT and OT
RA nursing care
Monitor for complications such as Sjögren’s syndrome
S/S of Sjögren’s syndrome
Excessively dry eyes and dry mouth
RA patient education
Take warm shower in morning to relieve morning stiffness, engage in physical activity to preserve ROM, use assistive devices as needed for safety
Osteoarthritis vs RA: pain
Osteoarthritis: end of day pain; patient will have more pain with activity that is relieved with rest. After sleeping all night, patient will feel better in the morning
RA: patients will have morning stiffness and pain that is relieved through activity
The replacement of a diseased joint with a prosthetic joint
Arthroplasty (most common include knee, hip, and shoulder)
Contraindications for arthroplasty
Active infection, advanced osteoporosis
Arthroplasty pre-op care
Administration of epoetin Alfa or autologous blood donation several weeks before procedure, remind patient to shower with antiseptic soap to decrease risk for infection
Arthroplasty post-op care
Monitor for DVT or PE, prevent thromboembolism through (SCDs, stockings, anticoagulants, start exercise and activity soon after surgery), monitor for infection, bleeding, and neurovascular compromise (pulses, color, temp, etc)
Arthroplasty patient education
Take antibiotics prior to any dental or invasive procedure (for the rest of life)
Hip replacement post-op care
Abduction device in place, ensure heels are elevated off bed to prevent injuries, provide trapeze device for repositioning, monitor for signs of joint dislocation (increased hip pain, affected leg appears shorter or internally rotated)
Hip replacement patient education
Use elevated toilet seat, avoid low chairs (avoid hip flexion over 90 degrees), do not cross ankles or legs (can cause joint dislocation)
Knee replacement post-op care
Continuous passive motion if ordered, do NOT place pillow or knee gatch beneath the knee (can result in flexion contractures), educate patient to avoid kneeling or deep knee bends following procedure
Metabolic bone disorder causing a decrease in bone mass leading to fragile bones and increased risk for bone fractures
Osteoporosis
What is the precursor to osteoporosis?
Osteopenia
