MHR stands for...

Which of the following is a common site to measure the pulse manually?

• The wrist

• The ankle

• The shoulder

• The neck

THR stands for...

• Target Half Rate

• Target Heart Rate

• Timely Heart Rate

• Tangible Heart Rate

Why does pulse rate increase during exercise?

• Oxygen and carbon dioxide must be removed from the body ASAP

• Gas exchange must happen more quickly than when a person is at rest

• Oxygen must be moved to the lungs and carbon dioxide must be moved to cells more quickly

• Carbon dioxide must be moved to the kidneys to be excreted

If your pulse rate increases, your heart is beating

• slower than before

• faster than before

• more forcefully than before

• with less pressure than before

A student measures his pulse rate while he is watching television and records it. Next, he walks to a friend’s house nearby and when he arrives, measures and records his pulse rate again.
