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?
A.
Turn off the CPM machine during mealtime.
B.
Maintain the client’s affected hip in an externally rotated position.
C.
Instruct the client how to adjust the CPM settings for comfort.
D.
Store the CPM machine under the client’s bed when not in use.
The correct answer and Explanation is :
The correct action is:
A. Turn off the CPM machine during mealtime.
Explanation:
A Continuous Passive Motion (CPM) machine is often used postoperatively following a total knee arthroplasty to improve range of motion and reduce the risk of joint stiffness. Proper use of the CPM machine is crucial for optimal recovery.
Turning off the CPM machine during mealtime is generally recommended because it ensures the client can eat comfortably without the machine interfering. Additionally, during mealtime, there is an opportunity for the client to rest and engage in other activities that may not be conducive to using the CPM machine.
Here’s why the other options are not correct:
B. Maintain the client’s affected hip in an externally rotated position: This option is not appropriate because after a total knee arthroplasty, the focus is typically on maintaining proper alignment of the knee rather than the hip. The CPM machine’s primary role is to ensure proper knee flexion and extension, and it does not directly manage the hip’s positioning.
C. Instruct the client how to adjust the CPM settings for comfort: While it’s important for clients to understand how to use their equipment, adjusting CPM settings should be done according to the physician’s or physical therapist’s orders. The settings are usually determined based on the surgical procedure and recovery goals. Allowing clients to adjust settings themselves could lead to improper use, which may impact recovery.
D. Store the CPM machine under the client’s bed when not in use: Storing the CPM machine under the bed is not advisable as it could lead to the machine being damaged or becoming inaccessible when needed. Proper storage involves placing the machine in a designated area where it is safe and ready for use according to the prescribed therapy schedule.
In summary, turning off the CPM machine during mealtime ensures comfort and practicality for the client while not disrupting the prescribed therapy protocol.
