A medical assistant is performing a body fat measurement on a patient. Which of the following areas should the assistant use to obtain an accurate measurement
A Gluteus maximus
Biceps
Infrailiac region
Triceps
The Correct Answer is C
A. Gluteus maximus: The gluteus maximus is not a commonly used site for body fat measurement.
B. Biceps: The biceps are not typically used for body fat measurement. Measurements are usually taken at sites with more subcutaneous fat.
C. Infrailiac region: The infrailiac region, located just above the iliac crest (hip bone), is a common site for measuring body fat, along with other areas such as the triceps and subscapular region.
D. Triceps: While the triceps can be used for body fat measurement, the infrailiac region is another standard site used for accuracy in some methods.

Correct Answer is B
Explanation
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.
Correct Answer is C
Explanation
A. 1: Checking the medication order against the label only once is insufficient for ensuring accuracy.
B. 2: While checking twice is better than once, the standard practice is to check three times for maximum accuracy.
C. 3: The "three checks" method involves checking the medication order against the label at three key points: when selecting the medication, when preparing it, and before administering it to the patient.
D. 4: Checking four times is not a standard practice and could be excessive; three checks are considered sufficient.
