What is considered a normal heart rate for an adult?

40-60 bpm
60-100 bpm
100-120 bpm
120-140 bpm

The correct answer is: 60-100 bpm

A normal resting heart rate for an adult typically ranges from 60 to 100 beats per minute (bpm). This range is established based on the body's need for oxygen and its response to various levels of activity, stress, and overall health. Heart rates below 60 bpm might indicate bradycardia, which can be a concern depending on the individual's health status and any accompanying symptoms. Conversely, rates over 100 bpm may indicate tachycardia, which can result from stress, anxiety, exercise, or underlying health conditions. Understanding the normal heart rate range is crucial for monitoring cardiovascular health and identifying potential health issues in patients.
