A type of Korotkoff sound that indicates the diastolic pressure in children and in some adults is

A.

tapping.

B.

knocking.

C.

silence.

D.

muffling

Answer and Explanation

The Correct Answer is D

A.    Tapping is the first Korotkoff sound and corresponds to the systolic pressure, not the diastolic pressure.
B.    Knocking does not describe any Korotkoff sound associated with the blood pressure reading.
C.    Silence is typically noted after the muffling sound and indicates the cessation of Korotkoff sounds, which can be used to assess diastolic pressure in adults, but it is not used in children.
D.    The muffling sound occurs before the disappearance of Korotkoff sounds and is often used to mark the diastolic pressure in both children and some adults, making it the correct answer.

C. Wiping the thermometer with alcohol helps sanitize it but does not directly influence the accuracy of the reading.
