What is the normal adult resting pulse rate?

• A. 40-60 bpm
• B. 50-70 bpm
• C. 100-120 bpm
• D. 60-100 bpm

Answer: (D)

Resting heart rate is the number of heartbeats per minute when the body is at rest. For a healthy adult, the typical resting rate falls between 60 and 100 beats per minute. This range reflects normal autonomic regulation of the heart when metabolic demands are low. Rates below 60 may be normal for some people, especially those who are very fit, but they can indicate bradycardia in others. Rates above 100 suggest tachycardia, which can arise from fever, dehydration, stress, stimulants, or underlying cardiac issues. To measure accurately, have the person sit or lie quietly for several minutes, palpate a peripheral pulse (such as the radial pulse on the wrist), and count the beats for a full 60 seconds. Factors that influence the resting rate include fitness level, age, medications, caffeine or nicotine intake, recent activity, and fever.
