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.

Correct Answer is A
Explanation
Choice A rationale
Recommending consumption of cold items is a common intervention for managing stomatitis in clients receiving cancer treatment. Cold items can help to soothe the mouth and reduce pain. This is the correct choice.
Choice B rationale
Minimizing the use of gravies and sauces is not a standard intervention for managing stomatitis. While some clients may find these foods irritating, others may not.
Choice C rationale
Providing an alcohol-based mouthwash is not recommended for clients with stomatitis. Alcohol can dry out the mouth and exacerbate symptoms.
Choice D rationale
Discouraging drinking with a straw is not a standard intervention for managing stomatitis. Some clients may find that using a straw helps to bypass sore areas in the mouth.
Correct Answer is B
Explanation
Choice A rationale
While it’s important to prepare for a colonoscopy by cleaning out the colon, drinking full liquids until 6 hours before the procedure may not be recommended. The colon needs to be empty to allow the doctor to view it clearly during the colonoscopy. Therefore, this choice is incorrect.
Choice B rationale
Moderate sedation is often used during a colonoscopy. This means you’ll be relaxed and somewhat drowsy, but you’ll still be awake. You might not remember much about the actual procedure because of the sedative. Therefore, this choice is correct.
Choice C rationale
During a colonoscopy, you will likely start by lying on your left side. However, you may be asked to adjust your position during the procedure to allow the doctor to better examine certain parts of your colon. Therefore, this choice is incorrect.
Choice D rationale
Warming the liquid bowel preparation before drinking it is not typically recommended. The bowel preparation involves drinking a solution that helps clear out the colon, but it doesn’t need to be warmed. Therefore, this choice is incorrect.
