Final answer:
If the heart rate (HR) is less than 100 for children, it can be considered within the normal range. Resting heart rates can vary depending on age and activity level. For children, a normal resting heart rate usually falls between 70-100 beats per minute (bpm).
Step-by-step explanation:
If the heart rate (HR) is less than 100 for children, it can be considered within the normal range. Resting heart rates can vary depending on age and activity level. Newborns usually have higher resting heart rates, which gradually decrease until young adulthood and then increase with age. For children, a normal resting heart rate usually falls between 70-100 beats per minute (bpm).
