What is the normal adult resting heart rate range?

• A. 50-90
• B. 70-110
• C. 65-95
• D. 60-100

Answer: (D)

The main idea is the normal resting heart rate for a healthy adult at rest. The widely accepted reference range is about 60 to 100 beats per minute. This range is used in routine nursing assessments because it covers most adults who are not ill and not highly athletic. Values within this span indicate a typical resting state, while a rate below 60 can be bradycardia and may occur in well-trained athletes or with certain medications, and a rate above 100 can be tachycardia and may reflect fever, dehydration, stress, or cardiac or systemic conditions. When you see rates outside this range, it prompts closer look, but many people can fall outside briefly without issue.
