Patients who have diabetes mellitus should have dilated eye exams at which of the following frequencies?

A. Sitting behind a desk and looking at the computer: This posture may appear distant and disinterested, as it creates a physical barrier and lacks engagement.
B. Sitting on the edge of a chair and leaning forward: This body language conveys attentiveness and engagement, indicating care and interest in the conversation with the patient.
C. Standing across the room. Standing across the room can seem impersonal and distant, which may not effectively communicate care and interest.
D. Standing over the patient: Standing over the patient can be intimidating and may convey dominance rather than care and support.

Correct answer: B
A. Place the left electrode on the most distal portion of the left limb, and place the right electrode on the most proximal portion of the right limb: The left limb is amputated, so electrodes cannot be placed on the distal portion of the left limb; the right limb's electrode should be placed according to standard practice.
B. Place the left electrode on the most distal portion of the left limb, and place the right electrode on the right groin: For an amputation, the electrode for the absent limb can be placed on the corresponding part of the trunk (such as the groin) to obtain accurate readings.
C. Place the left electrode on the left mid thigh, and place the right electrode on the right mid thigh: With an above-the-knee amputation, placing electrodes on the mid-thigh of the amputated side is not feasible; placement should follow appropriate protocol for the missing limb.
D. Place the left electrode at the most proximal portion of the right limb, and place the right electrode at the most distal portion of the right limb: This does not accommodate for the left limb amputation and does not follow standard electrode placement practices.
