Question

pulse is a direct measure of
a heart rate
b blood pressure
c stroke volume
d cardiac output
question 8

Explanation:

The pulse represents the rhythmic expansion and contraction of arteries due to the heartbeat. Each pulse corresponds to one heartbeat. Heart rate is defined as the number of times the heart beats per minute. Measuring the pulse (counting the number of pulses in a minute) directly gives the heart rate. Blood pressure is measured using a sphygmomanometer and is about the force of blood on artery walls. Stroke volume is the amount of blood pumped by the heart per beat (measured through techniques like echocardiography). Cardiac output is the product of heart rate and stroke volume (calculated, not directly measured by pulse).

Answer:

A. heart rate
