The top (higher) number is the systolic pressure, which reflects the pressure in arteries when the heart contracts and pumps blood.

Question 2

A CNA wraps the blood pressure cuff around a resident's arm. The lower edge of the cuff should be placed how far above the antecubital space (inner elbow)?

Accepted Answer

1 inch

The lower edge of the cuff should be placed approximately 1 inch (2–3 cm) above the antecubital space to allow room for the stethoscope.

Question 3

Which of the following conditions can cause a falsely HIGH blood pressure reading?

Accepted Answer

Resident talking during the measurement

The first Korotkoff sound heard as the cuff deflates represents the systolic blood pressure.
