A nurse is caring for a patient who is postoperative following a total knee arthroplasty and is using a continuous passive motion (CPM) device.
What actions should the nurse take?
Elevate the head of the bed 45 degrees before starting the CPM device.
Instruct the patient to increase the degree of flexion as tolerated.
Ensure the frame joint is in a flexed position before placing the leg onto the device.
Ensure the knee joint is positioned over the CPM device frame joint.
The Correct Answer is D
Choice A rationale
Elevating the head of the bed 45 degrees before starting the CPM device is not necessary. The position of the bed does not affect the operation of the CPM device.
Choice B rationale
Instructing the patient to increase the degree of flexion as tolerated is not the nurse’s responsibility. The degree of flexion is usually set by the healthcare provider or physical therapist.
Choice C rationale
Ensuring the frame joint is in a flexed position before placing the leg onto the device is not necessary. The CPM device should be set up according to the manufacturer’s instructions and the healthcare provider’s orders.
Choice D rationale
Ensuring the knee joint is positioned over the CPM device frame joint is crucial. Proper alignment of the patient’s knee joint with the CPM device’s joint ensures effective and safe operation of the device.

Choice B rationale
Providing a diet that is low in protein is not a recommended intervention for a patient experiencing sickle cell crises. Patients with sickle cell disease need a balanced diet that includes adequate protein to support tissue repair and growth.
Choice C rationale
Decreasing fluid intake to 1,500 mL daily is not a recommended intervention for a patient experiencing sickle cell crises. Adequate hydration is important to prevent sickling of cells and to maintain blood volume.

Choice A rationale
Giving a clear liquid diet is not necessary before surgery for acute appendicitis. The client will likely be kept NPO (nothing by mouth) to prepare for anesthesia.
Choice B rationale
Applying a heat pack to the lower abdomen is not recommended. Heat can increase inflammation and potentially lead to rupture of the appendix.
Choice C rationale
Administering an enema is not recommended. This could potentially cause the inflamed appendix to rupture.
Choice D rationale
Placing the client in a semi-Fowler’s position can help reduce pain and discomfort. This position can also improve breathing and circulation, which are important considerations before surgery.
