Question 25

The instrument used to listen to the heart is called a stethoscope.

A stethoscope is a medical instrument specifically designed for auscultation, allowing healthcare professionals to listen to internal sounds of a patient's body, including the heart.

A) sphygmomanometer

A sphygmomanometer is used to measure blood pressure, not to listen to heart sounds. While it is crucial in assessing cardiovascular health, it does not provide auditory information about the heart's functioning.

B) stethoscope

The stethoscope is the correct answer, as it is the primary tool used by physicians and nurses to listen to heartbeats and other internal sounds, making it essential for diagnosing various heart conditions.

C) autoclave

An autoclave is a device used for sterilization of medical instruments through high-pressure steam. It does not play any role in auscultation or the assessment of heart sounds.

D) blood pressure cuff

A blood pressure cuff is part of the equipment used to measure blood pressure, often in conjunction with a sphygmomanometer. However, like the sphygmomanometer, it does not allow for listening to the heart.

Conclusion

The stethoscope is the definitive instrument for listening to heart sounds, which is critical for evaluating heart health. All other options, while important in their respective functions, do not serve the purpose of auscultation and thus cannot be considered correct in this context.
