Over which artery should the stethoscope be placed for proper blood pressure measurement?

A. Ileal: The ileal artery does not exist as a site for blood pressure measurement.There is no "ileal artery" accessible for blood pressure measurement on the body's surface.

B. Femoral: The femoral artery can be used in special circumstances (e.g., neonatal or lower-extremity monitoring), but it is not the standard site for routine blood pressure measurement in adults.

C. Radial: The radial artery is palpable and used for arterial line placement, but it is not the standard site for auscultatory blood pressure measurement using a sphygmomanometer.

D. Brachial: The brachial artery, located in the antecubital fossa of the upper arm, is the recommended site for accurate blood pressure measurement. Placement of the stethoscope over the brachial artery allows correct auscultation of Korotkoff sounds during cuff deflation.

“Illness” refers to the subjective experience of symptoms and the personal, social, and emotional responses to a health condition. It is distinct from “disease,” which denotes the objective, pathophysiologic process identified by healthcare providers. Understanding a patient’s perception of their illness helps guide individualized care and patient-centered communication.
