tapping.
knocking.
silence.
muffling
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.

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.
