Orthopedic Nursing Exam Study Questions and
Answers| Latest Version 2024-25
What is Bursa - ✔✔sac filled with synovial fluid that cushions movement of tendons,
ligaments, and bones over bones (shoulder, elbow, hip, knee)
What does flaccid mean - ✔✔muscle is limp (could be due to lower motor neuron lesions)
What does spastic mean - ✔✔muscle with greater than normal tone (could be due to upper
motor neuron lesions)
What does hypertrophy mean - ✔✔increase in size of muscle fibers (exercise)
What does atrophy mean - ✔✔decrease in size of muscle (bedrest, immobility)
What fibrous tissue are muscles incased in - ✔✔fascia
What causes muscle movement - ✔✔contraction
What is the contractile unit of skeletal muscle that contains actin and myosin -
✔✔sarcomere
What do muscle cell fibers react to - ✔✔electrical stimulation
What provides energy for more strenuous muscle activity - ✔✔Anaerobic pathways using
glucose metabolized from stored glycogen
, What is sensations of burning, tingling, or numbness could be caused by pressure on nerves or
circulatory impairment. - ✔✔paresthesias
At what age do bones become fragile and lose bone mass - ✔✔30
Important rules in MRI - ✔✔no metal, pacemakers, etc

What is a bone scan - ✔✔injection of radioisotope then in 2-3 hours scan is done to detect
metastatic and primary bone, tumors, osteomyelitis, fractures, & to monitor degenerative bone
disease
Nursing interventions in bone scans - ✔✔assess allergies, have pt empty bladder so pelvic
bone can be visualized, flushing and warmth from radioisotope, drink plenty of fluids after test.
What is an arthoscopy - ✔✔Large bore needle is inserted into joint and joint is distended
with saline, arthroscope is introduced to visualize joint structures, synovium.
What are nursing interventions for arthroscopy - ✔✔joint is wrapped with a compression
dressing to control swelling, ice is applied, joint is kept extended and elevated, neurovascular
status monitored, analgesics administered.
What's arthrocentesis - ✔✔Joint aspiration to obtain synovial fluid using aseptic technique.
