What is the normal pulse rate for a resting adult?

1. 40-60 beats per minute

2. 60-90 beats per minute

3. 90-110 beats per minute

4. 100-120 beats per minute

The correct answer is: 60-90 beats per minute

The normal pulse rate for a resting adult typically falls within the range of 60 to 100 beats per minute. When considering this range, a pulse rate of 60 to 90 beats per minute is often cited as a standard reference, aligning with physiological norms for resting adults. This range accounts for variations among individuals, including factors such as age, fitness level, and overall health. At rest, the body requires a certain amount of oxygenation, and the heart rate adjusts accordingly to maintain adequate blood flow and oxygen delivery to tissues without unnecessary exertion. A pulse rate below 60 beats per minute is often indicative of bradycardia, which may signal underlying health concerns or could be a normal finding in well-trained athletes. Rates above 100 beats per minute at rest can indicate tachycardia, which may be associated with numerous factors including stress, illness, or dehydration. Thus, the selection of a pulse rate range in the 60-90 beats per minute category as normal for a resting adult reflects a well-established health standard in clinical practice.
