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 A
Explanation
A. Ensure the skin is clean and dry. This is the correct action. Sweating can interfere with electrode adhesion and signal quality, so the skin should be cleaned and dried to ensure a good contact for accurate EKG readings.
B. Apply conductive gel to the patient's chest. Conductive gel is typically used with certain types of electrodes, but in the case of disposable adhesive EKG electrodes, it is not necessary and may not improve tracing quality.
C. Shave the electrode sites. Shaving may be necessary if the patient has a lot of body hair, but it is not the first step when dealing with sweating. Drying the skin is more immediate and essential.
D. Place the electrodes below the clavicle. Electrode placement should follow standard EKG guidelines, and moving them to non-standard positions like below the clavicle can result in inaccurate readings.
Correct Answer is B
Explanation
A. NIH (National Institutes of Health): NIH conducts biomedical and public health research but does not regulate laboratory testing.
B. CLIA (Clinical Laboratory Improvement Amendments): This is correct. CLIA regulates laboratory testing and ensures quality standards in the clinical office setting.
C. HHS (Department of Health and Human Services): HHS oversees many health-related programs and agencies, but CLIA specifically regulates laboratory testing.
D. OSHA (Occupational Safety and Health Administration): OSHA regulates workplace safety, not laboratory testing.
