A nurse is caring for a client who has a prescription for a continuous passive motion (CPM) machine following a total knee arthroplasty. Which of the following actions should the nurse take?

Turn off the CPM machine during mealtime.

Maintain the client's affected hip in an externally rotated position.

Instruct the client how to adjust the CPM settings for comfort.

Store the CPM machine under the client's bed when not in use.

Answer and Explanation

The Correct Answer is A

- A. Correct. The nurse should turn off the CPM machine during mealtime, as it can interfere with the client's ability to eat and drink comfortably. The nurse should also turn off the CPM machine when transferring or repositioning the client, or when performing wound care or other interventions on the affected leg.

- B. Incorrect. The nurse should maintain the client's affected hip in a neutral position, as external rotation can cause malalignment of the prosthesis and impair healing. The nurse should use pillows or wedges to support the leg and prevent rotation or abduction of the hip joint.

- C. Incorrect. The nurse should not instruct the client how to adjust the CPM settings, as this can compromise the prescribed range of motion and speed of the device. The nurse should follow the provider's orders and check with them before making any changes to the CPM settings. The nurse should also monitor the client's pain level and administer analgesics as needed to facilitate compliance with the therapy.

- D. Incorrect. The nurse should not store the CPM machine under the client's bed when not in use, as this can pose a safety hazard and damage the equipment. The nurse should place the CPM machine on a stable surface near the bed and ensure that it is plugged into a grounded outlet and has adequate battery backup in case of power failure.

Correct Answer is D

Explanation

- A. Diarrhea is not an adverse effect of amitriptyline, which is a tricyclic antidepressant (TCA). Diarrhea may be caused by other factors, such as infection, food intolerance, or stress. Therefore, this choice is incorrect.

- B. Frequent urination is not an adverse effect of amitriptyline either. Frequent urination may be a sign of diabetes, urinary tract infection, or other conditions that affect the kidneys or bladder. Therefore, this choice is also incorrect.

- C. Excessive salivation is not an adverse effect of amitriptyline as well. Excessive salivation may be due to increased production of saliva, difficulty swallowing, or mouth irritation. Therefore, this choice is incorrect too.

- D. Blurred vision is an adverse effect of amitriptyline and other TCAs. Amitriptyline can cause anticholinergic effects, such as dry mouth, constipation, urinary retention, and blurred vision. These effects are more pronounced in older adults and can impair their daily functioning and quality of life. Therefore, this choice is correct and the nurse should identify it as an adverse effect of the medication.

A. Perform gastrostomy feedings through a client's established gastrostomy tube B. Determine if the PRN pain medication administered 30 min ago has helped C. Provide instructions about client care to a family member over the telephone D. Teach a client how to measure their own blood pressure E. None F. None

Correct Answer is A

Explanation

A. Performing gastrostomy feedings through an established gastrostomy tube is within the scope of practice for an AP, as it is a routine, non-complex task.
B. Evaluating the effectiveness of pain medication requires assessment skills, which fall under the nurse’s scope of practice.
C. Providing client care instructions requires nursing judgment and should be done by the nurse.
D. Teaching a client how to measure their blood pressure involves client education, which is the nurse’s responsibility.
