A nurse is initiating the use of a continuous passive motion (CPM) device for a client following a total knee arthroplasty. Which of the following actions should the nurse take?
A.
Align the client’s joints with the joints on the frame.
B.
Pad the CPM device with a thick pillow.
C.
Place the client in high-Fowler’s position.
D.
Set the degree of flexion and extension as tolerated by client.
The correct answer and Explanation is :
The correct answer is:
A. Align the client’s joints with the joints on the frame.
Explanation:
When initiating the use of a Continuous Passive Motion (CPM) device following total knee arthroplasty, it is crucial to align the client’s joints with the joints on the CPM device frame. This alignment ensures that the device functions properly and provides the intended range of motion (ROM) to the knee joint. Proper alignment helps in achieving optimal therapeutic benefits from the CPM device and minimizes the risk of injury or discomfort to the patient.
Here’s why the other options are not appropriate:
B. Pad the CPM device with a thick pillow: Padding with a thick pillow is not recommended because it may interfere with the proper function of the CPM device. The device is designed to fit snugly around the limb, and adding extra padding can disrupt the device’s alignment and effectiveness, and possibly cause discomfort or pressure points.
C. Place the client in high-Fowler’s position: Positioning the client in a high-Fowler’s position is generally not recommended when using a CPM device. This position may not support the proper alignment of the leg and could affect the effectiveness of the device. Typically, a supine or slightly elevated position with proper leg support is preferred for CPM therapy.
D. Set the degree of flexion and extension as tolerated by client: While it is important to adjust the degree of flexion and extension based on the client’s tolerance, the primary initial action is to ensure proper alignment of the joints with the CPM device. The degree of flexion and extension can be adjusted gradually as therapy progresses and should be based on the client’s individual recovery plan and surgeon’s recommendations.
In summary, aligning the client’s joints with the joints on the CPM device frame is essential for ensuring the device operates correctly and provides the therapeutic benefits needed for post-surgical recovery.
