ATI MUSCULOSKELETAL SYSTEM UPDATED
ACTUAL QUESTIONS AND CORRECT
ANSWERS COMPREHENSIVE STUDY GUIDE
●● nuclear scan
Answer: radioactive material injected hours before scan. Repeat scans at
24, 48, 72 hours. Bone scan detects tumors, fractures, bone disease.
Gallium scan are more sensitive than bone scan
●● DXA
Answer: used to determine bone mass and presence of osteoporosis
●● electromyography
Answer: needles placed into muscle and electrical activity recorded
during muscle contraction. Used to diagnose cause of muscle weakness.
●● arthroplasty
Answer: replacement of a diseased joint with a prosthetic joint. Used for
patients with osteoarthritis, rheumatoid arthritis, trauma, or congenital
defects.
●● *joint pain
*crepitus
, *swelling
Answer: patient symptoms for arthroplasty
●● *current/recent infection
*arterial insufficiency to affected extremity
Answer: Contraindications for arthroplasty
●● *adminster epoetin alfa to increase Hgb
*autologous blood donation
*advise patient to scrub w/antiseptic soap the night before and morning
of surgery
Answer: pre-op care for arthroplasty
●● *initiate continuous passive motion (CPM) machine immediately
after surgery (if ordered)
*DO NOT place pillow under knee (or use knee gatch) in order to
prevent flexion contractures.
*administer analgesics, antibiotics, anticoagulants, ice therapy
*perform neurovascular checks every 2-4 hours
*patient should NOT kneel or do deep-knee bends.
Answer: knee arthroplasty post-op care
