A medical assistant is preparing to place lower-limb electrodes on a patient who has a left above the knee amputation. Which of the following actions should the assistant take when placing the lower-limb electrodes?
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.
Place the left electrode on the most distal portion of the left limb, and place the right electrode on the right groin.
Place the left electrode on the left mid thigh, and place the right electrode on the right mid thigh
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
The Correct Answer is B
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.
