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 C
Explanation
Choice A: This is incorrect because taking iron supplement with an antacid can reduce its absorption and effectiveness. The client should take iron supplement on an empty stomach or with a source of vitamin C to enhance its absorption.
Choice B: This is incorrect because drinking liquid iron supplement undiluted can stain the teeth and cause irritation to the mouth and throat. The client should dilute liquid iron supplement with water or juice and drink it through a straw.
Choice C: This is correct because increasing fiber intake while taking iron supplement can help prevent constipation, which is a common side effect of iron supplementation. The client should also drink plenty of fluids and exercise regularly to promote bowel movements.
Choice D: This is incorrect because notifying the doctor if stools turn black is not necessary as it is a normal and harmless effect of iron supplementation. The client should only notify the doctor if stools are tarry, bloody, or have a foul odor, which can indicate gastrointestinal bleeding.
Correct Answer is B
Explanation
Choice A reason: Blurred vision is not an expected side effect of digoxin, but a sign of digoxin toxicity, which requires immediate medical attention.
Choice B reason: This is the correct answer because digoxin can cause hypokalemia (low potassium levels), which increases the risk of digoxin toxicity. Therefore, clients taking digoxin need to have their potassium levels monitored regularly and consume foods rich in potassium.
Choice C reason: Antacids can interfere with the absorption of digoxin and reduce its effectiveness. Clients taking digoxin should avoid taking antacids within two hours of taking the medication.
Choice D reason: Weighing oneself every other day is not related to digoxin therapy, but to fluid balance. Clients with heart failure, who are often prescribed digoxin, need to monitor their weight daily and report any significant changes to their health care provider.
