What is the normal heart rate range for adolescents?

• A. 60-90
• B. 55-95
• C. 65-110
• D. 60-100

Answer: (D)

Resting heart rate in adolescents typically falls within about 60 to 100 beats per minute. This range reflects normal variation due to fitness level, autonomic nervous system tone, and daily state (resting vs. stress). Values under 60 can occur in well-trained teens and may be normal for them, while rates above 100 at rest can indicate fever, dehydration, anxiety, or illness. The 60-100 range aligns with the common expectation for adolescents at rest, capturing healthy values at both ends of the spectrum. The other ranges either miss healthy resting values or include numbers that are not usually considered normal for teens at rest.
