What is the primary function of a stethoscope?

The primary function of a stethoscope is to listen to sounds generated inside the body. This tool is essential for healthcare professionals, particularly in assessing the heart, lungs, and other bodily functions. By placing the stethoscope on the surface of the skin, clinicians can detect various sounds, such as heartbeats, breath sounds, and bowel sounds, which provide valuable information about a patient's health status.

While taking blood pressure, measuring temperature, or providing audible feedback during exams might be associated with patient assessment, these actions are not the primary purpose of a stethoscope. Blood pressure is typically taken with a sphygmomanometer, and temperature is measured using a thermometer. The stethoscope specifically aids in auscultation—the process of listening to internal sounds, making it a vital instrument in clinical practice.
