Nokea
You are caring for a patient who had a partial knee replacement 2 days ago. She has orders for CPM for 2 hours four times per day at 35 degrees of flexion. Which would concern you the most?
- A. The patient's leg and the CPM machine are in alignment with the rest of the patient's body.
- B. The patient complains of severe pain with each flexion of the knee.
- C. The patient is using relaxation breathing to prevent tensing of the leg muscles while on the CPM machine.
- D. The platform of the CPM machine is centered beneath the patient's knee.
Correct Answer: B
Rationale: Severe pain during CPM use suggests potential complications (e.g., improper settings or joint issues), requiring immediate assessment. Other options indicate proper use or management.

You are caring for a young child with hip dysplasia who is in a spica cast. An important nursing concern is
- A. Assessing circulation to the fingers and hands.
- B. Moving the patient carefully without using the abductor bar.
- C. Keeping the patient's hips elevated above the heart.
- D. Aligning the hips each time the patient is turned.
Correct Answer: B
Rationale: In a spica cast, the abductor bar maintains hip alignment and should not be used to move the patient, as this could disrupt the cast or alignment. Circulation is assessed in the toes, not fingers.
A patient has had reconstructive surgery on her right foot and must be non-weight-bearing for 6 to 8 weeks. She has problems with balance at times. Which device(s) would be most helpful to her during this period?
- A. Knee walker
- B. Crutches
- C. Wheeled walker
- D. Abductor pillow
- E. Splint
Correct Answer: A,C
Rationale: A knee walker or wheeled walker supports non-weight-bearing mobility and balance. Crutches are less stable for patients with balance issues.
You are working with a patient whose left leg is weak. You are instructing her on walker use. Which instruction is most appropriate?
- A. Move your right leg forward with the walker, and then move your left leg.
- B. Move the walker forward, and then move your left leg forward, followed by your right leg.
- C. Move the walker forward, and then move your right leg forward, followed by your left leg.
- D. Move the walker and your left leg forward at the same time, and then move your right leg forward.
Correct Answer: C
Rationale: The correct instruction is to move the walker forward, then the unaffected (right) leg, followed by the weak (left) leg for stability.
A patient came to the ER complaining of pain in her elbow after a fall. The x-ray shows fractured ulna at the olecranon process. There is also a suspected fracture of the radius. Which diagnostic test would be most helpful in determining a complete diagnosis?
- A. CT scan
- B. MRI
- C. Bone scan
- D. Electromyelogram
Correct Answer: A
Rationale: A CT scan provides detailed imaging of bones, making it ideal for confirming suspected fractures like the radius fracture. MRI is better for soft tissue, bone scans for bone activity, and electromyelograms assess nerve function.
What are the articular surfaces in a total knee replacement?
- A. A metal tibial component that articulates with the plastic surface of the femoral component
- B. A metal femoral component that articulates with the plastic fibula component
- C. The patella is replaced with plastic or similar substance or has plastic affixed to the back to provide a smooth articular surface
- D. The patella, tibia, and femur are replaced with plastic or polyethylene components
Correct Answer: A,C
Rationale: In total knee replacement, the tibial component (metal) articulates with the femoral component (plastic), and the patella may have a plastic surface for smooth movement.
