What is the normal resting heart rate range for a healthy adult?

• A. Approximately 60 to 100 beats per minute.
• B. 40 to 60 beats per minute.
• C. 100 to 120 beats per minute.
• D. 120 to 140 beats per minute.

Answer: (A)

At rest, a healthy adult’s heart rate is typically between 60 and 100 beats per minute. This range reflects normal autonomic balance when the body isn’t exercising or stressed. A lower resting rate, around 40–60 bpm, can be normal for people who are very fit because their hearts pump more blood per beat and don’t need as many beats per minute to maintain circulation. Rates well above 100 bpm at rest, such as 100–120 or 120–140, are generally considered elevated and can indicate tachycardia or other conditions that may need medical attention. To measure accurately, rest quietly for several minutes in a comfortable position, away from stimulants like caffeine or nicotine.
