During auscultation, what instrument is used to listen to heart, lungs, and other internal sounds?

• A. Stethoscope
• B. Sphygmomanometer
• C. Ophthalmoscope
• D. Otoscope

Answer: (A)

Auscultation relies on a stethoscope to hear the body's internal sounds. The stethoscope’s chest piece captures vibrations from the heart, lungs, and other organs and transfers them through the tubing to the clinician’s ears, letting you assess sound quality, rate, rhythm, and breath sounds. The other devices are for different purposes: a sphygmomanometer measures blood pressure, an ophthalmoscope examines the inside of the eye, and an otoscope looks into the ear canal. So the instrument used for listening during auscultation is the stethoscope.
