- B. Partial thromboplastin time (PTT)

While teaching the client, what can the nurse explain about the purpose of stump bandaging?
- A. It lengthens and tones the muscles.
- B. It maintains joint flexibility.
- C. It shapes the stump for prosthesis use.

Of the following emergency measures, which one should the nurse perform first?
- A. Check the victim's breathing.
- B. Cover the victim with a blanket.
- C. Move the victim to the curb.
- D. Assess the victim for injuries.
Correct Answer: A
Rationale: In an emergency, the nurse must first assess the victim's breathing to ensure airway patency and adequate oxygenation, following the ABCs (Airway, Breathing, Circulation) of basic life support. Other actions are secondary.
Which evidence is the best indication that the client who had a knee arthroplasty is recovering according to expected outcomes and no longer needs the continuous passive motion (CPM) machine?
- A. The client has minimal pain when ambulating.
- B. The client can flex the operative knee 90 degrees.
- C. The client can tolerate full weight bearing.
- D. The edges of the client's surgical wound are approximated.

What equipment is best for preventing external rotation of the operative leg when caring for a client with a total hip replacement?
- A. A footboard
- B. A trochanter roll

Rationale: A trochanter roll placed along the hip prevents external rotation of the operative leg, maintaining proper alignment post-hip replacement. The other options do not specifically address rotation.
The female client diagnosed with osteoporosis tells the nurse she is going to perform swim aerobics for 30 minutes every day. Which response is most appropriate by the nurse?
- A. Praise the client for committing to do this activity.
- B. Explain to the client walking 30 minutes a day is a better activity.
- C. Encourage the client to swim every other day instead of daily.
- D. Discuss with the client how sedentary activities help prevent osteoporosis.
Correct Answer: B
Rationale: Walking, a weight-bearing exercise, better promotes bone density than swimming for osteoporosis. Daily swimming is less effective, sedentary activities worsen osteoporosis, and praise ignores efficacy.
