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. Ischemia: Ischemia refers to the lack of blood flow to tissues, which can lead to tissue damage or death, but it is not related to swelling due to fluid accumulation.
B. Edema: Edema is the correct term for tissue swelling caused by the accumulation of interstitial fluids, making this the correct choice.
C. Infarction: Infarction refers to tissue death due to a lack of blood supply, not to swelling caused by fluid accumulation.
D. Gangrene: Gangrene is the death of body tissue due to a lack of blood flow or severe infection, not related to fluid accumulation and swelling.

A. Applying powder to the site: Powder should not be applied to the site as it can interfere with electrode adhesion and signal transmission.
B. Wiping the site with alcohol and allowing to air dry: Wiping the site with alcohol helps to remove oils and debris, improving electrode adhesion and signal quality. Allowing the site to dry ensures proper contact between the electrode and the skin.
C. Taping the electrodes to the skin: Taping is not necessary if the electrodes are properly adhered with the adhesive backing. Excessive taping could cause discomfort or interfere with the electrode function.
D. Allowing the electrodes to sit for several hours before application: Electrodes should be applied immediately after preparation. Allowing them to sit for an extended period is not necessary and does not improve the quality of the EKG.
