Practice Question

 When measuring blood pressure, the second sound heard indicates which component of the blood pressure reading?

Answer Choices:

Correct Answer:

Diastolic pressure

Rationale:

♦️ The second important sound identified—usually when Korotkoff sounds muffle or disappear—marks diastolic pressure.

♦️ Diastolic pressure reflects the pressure inside arteries when the heart relaxes between beats.

♦️ It gives information about peripheral vascular resistance, an essential cardiovascular indicator.

♦️Proper recognition prevents misinterpretation of BP readings, ensuring accuracy.

♦️Diastolic levels help determine risks for conditions like hypertension, stroke, and heart failure.

✖ Incorrect Answers Rationale (2 points each):

Auscultatory gap

♦️ This is a temporary disappearance of Korotkoff sounds, not the second sound.

♦️ It is a measurement artifact and not a BP component.

Systolic pressure

♦️Systolic is marked by the first Korotkoff sound, not the second.

♦️It represents ventricular contraction, not relaxation.

Pulse pressure

♦️Pulse pressure is the difference between systolic and diastolic, not heard as a Korotkoff sound.

♦️It is not identified during auscultation.
