Melva is scheduled for an elective surgery. The surgeon comes to the preoperative area to review the surgical procedure with her. Alternatives are discussed, along with the benefits and risks associated with the surgery. Melva says she understands everything. This is:

Choice A reason: While controlling pain is a benefit, it is not the primary purpose of a CPM machine.

Choice B reason: Relieving foot swelling is not the main function of a CPM machine.

Choice C reason: Strengthening leg muscles is not the direct purpose of a CPM machine; it is designed to move the joint without the patient's muscles being used.

Choice D reason: The primary purpose of a CPM machine is to restore joint function by moving the joint through a prescribed range of motion, often after surgery, to prevent stiffness and increase circulation.

Choice A reason: Consuming alcohol as a coping mechanism for stress, especially before work, is concerning and unprofessional for a healthcare provider, as it can impair judgment and performance.

Choice B reason: Seeking advice from friends before asking someone out is a common social behavior and not typically a cause for concern.

Choice C reason: Taking deep breaths to manage anxiety is a healthy coping strategy and is not a cause for concern.

Choice D reason: Studying late into the night might indicate a high level of dedication or poor time management, but it is not inherently concerning unless it leads to chronic sleep deprivation.
