The development of what device enabled physicians to listen to sounds inside the body?

• A. Blood pressure cuff
• B. Thermometer
• C. Otoscope
• D. Stethoscope

Answer: (D)

Listening to internal body sounds, or auscultation, became possible with the invention of the stethoscope. This device lets a physician hear heart and lung sounds by amplifying them and transmitting them to the ears, enabling detection of things like heart murmurs and abnormal breath sounds that aren’t audible directly. The stethoscope, pioneered by René Laënnec in the early 1800s, revolutionized physical examination and diagnosis. The other tools measure or inspect different things: a blood pressure cuff records arterial pressure, a thermometer checks body temperature, and an otoscope is used to examine the ears.
