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?
Align the client's joints with the joints on the frame.
Pad the CPM device with a thick pillow.
Place the client in high-Fowler's position.
Set the degree of flexion and extension as tolerated by client.
The Correct Answer is A
Choice A: This is correct because aligning the client's joints with the joints on the frame can ensure proper functioning and comfort of the CPM device. The nurse should adjust the length and width of the device to fit the client's leg and secure it with straps.
Choice B: This is incorrect because padding the CPM device with a thick pillow can interfere with its movement and cause pressure on the leg. The nurse should use only thin padding or no padding at all for the CPM device.
Choice C: This is incorrect because placing the client in high-Fowler's position can cause flexion contractures and impair circulation in the leg. The nurse should place the client in supine or semi-Fowler's position with the leg elevated on pillows.
Choice D: This is incorrect because setting the degree of flexion and extension as tolerated by client can cause excessive pain and damage to the joint. The nurse should set the degree of flexion and extension according to the provider's prescription and gradually increase it as ordered.

Correct Answer is B
Explanation
Choice A: This is incorrect. Potassium 4.0 mEq/L is a normal value and does not indicate heart failure.
Choice B: This is correct. Brain natriuretic peptide (BNP) is a hormone that is released by the heart when it is stretched or overloaded. A high level of BNP indicates that the heart is working harder than normal and may have heart failure. A normal BNP level is less than 100 pg/mL, so 275 pg/mL is elevated and suggestive of heart failure.
Choice C: This is incorrect. Sodium 140 mEq/L is a normal value and does not indicate heart failure.
Choice D: This is incorrect. Calcium 9.0 mg/dL is a normal value and does not indicate heart failure.
Correct Answer is C
Explanation
Choice A reason: Applying moist heat to the incision while in bed is not an appropriate instruction, as it can increase the risk of infection, bleeding, or swelling at the site. The nurse should instruct the client to keep the incision dry and covered with a sterile dressing.
Choice B reason: Performing range of motion by adducting the hip is not an appropriate instruction, as it can cause dislocation or damage to the prosthesis. The nurse should instruct the client to avoid crossing their legs or turning their toes inward and to use an abduction pillow or wedge between their legs.
Choice C reason: Sitting in a straight-backed chair is an appropriate instruction, as it can prevent flexion contractures and promote circulation and healing in the hip joint. The nurse should instruct the client to use a raised toilet seat and a chair with armrests and avoid sitting for longer than 45 min at a time.
Choice D reason: Cleansing the surgical incision with hydrogen peroxide is not an appropriate instruction, as it can irritate or damage the tissue and delay wound healing. The nurse should instruct the client to use mild soap and water or saline solution to clean the incision and pat it dry gently.
