What is the normal range for adult resting heart rate?

• A. 50-70 bpm
• B. 60-100 bpm
• C. 70-90 bpm
• D. 80-110 bpm

Answer: (B)

The normal resting heart rate for adults typically falls within the range of 60 to 100 beats per minute (bpm). This range is considered the standard for healthy adults at rest and reflects the body's natural ability to maintain homeostasis. A heart rate below 60 bpm is often referred to as bradycardia, which can occur in athletes or individuals with high cardiovascular fitness levels due to increased heart efficiency. Conversely, a heart rate exceeding 100 bpm is classified as tachycardia and may indicate issues such as stress, anxiety, fever, or other underlying health conditions. The accepted range of 60 to 100 bpm thus encompasses the normal variations found in resting heart rates among the general adult population, making it the correct answer.
