Which of the following is a normal adult heart rate range?

• A. 40-60 bpm
• B. 60-100 bpm
• C. 100-140 bpm
• D. 30-50 bpm

Answer: (C)

Normal resting heart rate for healthy adults is typically between 60 and 100 beats per minute. This range represents the baseline pace of the heart when you’re at rest and not under stress or exertion. Rates below this range can be normal for some well-trained individuals, but generally indicate bradycardia, while rates above this range point to tachycardia and may signal dehydration, fever, anxiety, illness, or medication effects. The other ranges fall outside the typical resting range, so they’re not considered normal for most adults. Context matters, and individual factors like fitness level, medications, and overall health can shift what’s normal for a person.
