What is the normal pulse rate range for a newborn?

90-120 bpm
120-160 bpm
60-100 bpm
160-180 bpm

The correct answer is: 120-160 bpm

The normal pulse rate range for a newborn is typically between 120 and 160 beats per minute (bpm). This elevated heart rate is reflective of the newborn's physiological state and the transition from fetal to extrauterine life. Newborns need a faster heart rate to meet their metabolic demands, support growth, and maintain adequate circulation and oxygenation. While other options suggest different ranges, they do not accurately reflect the normal physiological parameters for newborns. For instance, a range of 90-120 bpm is more consistent with younger children or infants as they grow, while 60-100 bpm applies to older children and adults. An upper range of 160-180 bpm, while possible during periods of heightened activity, is not considered normal for resting newborns. Understanding the specific pulse norms for different age groups is essential for healthcare professionals and first responders in assessing a newborn's health quickly and effectively.
