Regarding the blood pressure in children, the diastolic pressure is assessed by the auscultation of a:

A.

murmur or swishing sound that increases with depression of the cuff.

B.

clear tapping that gradually grows louder

C.

louder knocking sound that occurs with each heartbeat.

D.

sudden change or muffling of the sound.

Answer and Explanation

The Correct Answer is D

A.    A murmur or swishing sound does not correspond to the diastolic pressure; it is more indicative of turbulent blood flow.
B.    Clear tapping sounds are heard at systolic pressure but do not indicate diastolic pressure.
C.    Knocking sounds are associated with systolic pressure, not diastolic.
D.    The muffling sound heard after the first Korotkoff sounds indicates the diastolic pressure in children and some adults, which is the correct method for assessing the diastolic reading.

Correct Answer is D

Explanation

A. A stronger pulse is typically associated with increased stroke volume or cardiac output.
B. Bradycardia is not directly related to a reduced stroke volume; pulse rate may not necessarily decrease.
C. An irregular pulse is more associated with arrhythmias or other cardiac conditions, not a reduction in stroke volume.
D. A weaker pulse is expected with a reduced stroke volume, as less blood is being pumped with each heartbeat, leading to a diminished pulse.
