The patient's plan of care includes using the continuous passive motion (CPM) machine. Which statement indicates the patient needs for further teaching?
"I can make my new knee stronger if I reset this thing to go faster and flex my knee more.
"I marched in the Marines for 20 years, and now I'm marching flat on my back?"
"I almost wish this CPM ran at night. The motor noise is soothing"
"My new knee will be glad to rest at night."
The Correct Answer is A
A. The CPM machine settings should be controlled by healthcare providers or according to prescribed protocols. Patients should not adjust speed or flexion angle independently, as improper settings can cause injury or impede healing.
B. This statement shows humor but does not indicate misunderstanding of CPM use.
C. Finding the motor noise soothing is acceptable and does not indicate a need for further teaching.
D. Allowing the knee to rest at night is appropriate; CPM use is typically during the day or as directed.

Correct Answer is A
Explanation
- Convert weight to kilograms:
82 lb ÷ 2.2 = 37.27 kg - Calculate safe dose range:
Minimum dose:10 mg × 37.27 kg = 372.7 mg/day
Maximum dose:12 mg × 37.27 kg = 447.24 mg/day
- Compare with ordered dose:
Ordered dose = 500 mg/day
Safe range = 372.7 mg to 447.24 mg/day
→ 500 mg exceeds the maximum safe dose (447.24 mg)
Final Answer:No, the order is not safe.
Correct Answer is B
Explanation
A. Inability to touch the nose with eyes closed is part of the finger-to-nose test, not the Romberg test.
B. A positive Romberg testis indicated when the patient sways or loses balancewhile standing with feet together and eyes closed. This suggests a problem with proprioception or the vestibular system.
C. Dizziness may occur during the test but does not constitute a positive resultunless accompanied by swaying or imbalance.
D. The patient being unable to keep eyes closedis not a criterion for a positive Romberg test. The test evaluates balance, not voluntary eye closure.
