Solution
The correct option is C Per minute Pulse is a term that signifies the throbbing of arteries as an effect of heartbeat and is counted by the number of beats per minute, which is called the pulse rate. The normal pulse rate (count of arterial pulse beats per minute) in a healthy adult at rest ranges from 72to80 beats per minute. However, the pulse rate may fluctuate with exercise, illness, injury and emotions. The pulse rate of an individual can be checked at various points on the body. These points are the neck, inside of the elbow, the wrist, groin, behind the knee, ankle joint and foot.
