The normal heart rate range for adolescents is which of the following?

• A. 60-90
• B. 65-105
• C. 60-100
• D. 50-110

Answer: (C)

Resting heart rate is the speed of the heart when a person is at rest, and it reflects how the autonomic nervous system balances heart function in a given age group. For adolescents, the typical quiet-state heart rate falls around 60 to 100 beats per minute. This range accounts for normal variation due to fitness, stress, body size, and measurement conditions. Values below about 60 can be seen in well-conditioned individuals or may indicate bradycardia, while values above about 100 can occur with fever, dehydration, anxiety, or illness. Among common options, 60-100 beats per minute best represents the normal adolescent resting heart rate. The other ranges either miss parts of the normal variation or include values that are not typical at rest.
