What is the acceptable heart rate range for preschoolers?

The acceptable heart rate range for preschoolers typically falls between 80 to 110 beats per minute. This range reflects the normal physiological responses and activity levels of children in this age group. Preschoolers have higher resting heart rates compared to older children and adults due to their smaller size and higher metabolic rates.

When considering the other options, the ranges provided either fall outside the commonly accepted values for preschoolers or are more appropriate for different age groups. For instance, the range of 60 to 100 beats per minute is typically considered normal for adults rather than young children. Similarly, ranges like 75 to 100 or 90 to 140 beat per minute do not align with established pediatric guidelines; the latter option suggests a range that is too high, as it includes rates that may be observed in infants rather than preschoolers. Thus, choosing the range of 80 to 110 accurately reflects the physiological norms for preschool-aged children.
