17 Questions

Which phase of Korotkoff's sounds is characterized by a swishing/whooshing sound?

Phase 2

Which phase provides the systolic pressure reading during blood pressure measurement?

Phase 1

What sound is heard during Phase 3 of Korotkoff's sounds?

Thump (softer than phase 1)

During which phase is the diastolic pressure reading first identified?

Phase 4

Which method is used for measuring blood pressure by applying external pressure on the artery?

Palpatory method

What is the term for the period of silence during blood pressure measurement using Korotkoff's sounds?

Auscultatory gap

What is the term used to describe the silence that occurs when the cuff pressure is released enough to allow normal blood flow?

Diastolic pressure reading

In which situation would a nurse most likely use the palpatory method for assessing blood pressure?

When Korotkoff's sounds cannot be heard

What can happen if a nurse assesses blood pressure immediately after a meal or while the client is in pain?

Incorrect systolic reading

Which common error in assessing blood pressure involves the temporary disappearance and reappearance of sounds at a lower level?

Auscultatory gap

What might occur if the cuff is wrapped too loosely or unevenly during blood pressure assessment?

Diastolic reading inaccurate

Which of these statements about diastolic pressure is correct?

It is the lower pressure present at all times in the arteries.

What is the typical range for a normal pulse pressure?

40 - 100 mmHg

Which phase of Korotkoff's sounds corresponds to the systolic pressure reading?

Phase I

What is the formula for calculating pulse pressure?

Pulse Pressure = (Systolic Pressure - Diastolic Pressure)

During the auscultatory gap, which Korotkoff sound is temporarily inaudible?

Phase III

What technique is used to measure blood pressure by detecting Korotkoff's sounds?

Auscultatory method

Learn about the differences between direct (invasive) and indirect (noninvasive) blood pressure monitoring methods. Explore the procedures, equipment, and accuracy of each method, including auscultatory and Korotkoff's sounds phases.
