In children, a normal heart rate decreases as age increases. Which category reflects this trend for awake infants?

The correct choice reflects the heart rate range for awake infants, which is indeed between 100 and 180 beats per minute. This range is considered normal and illustrates how heart rates are typically higher in younger populations compared to older children and adults.

As infants mature, their resting heart rates gradually decrease, making it essential to understand these parameters for accurate assessment. In infants, a heart rate below 100 would be indicative of bradycardia, which might signal potential health issues, while a rate above 180 could suggest tachycardia, requiring further evaluation.

Recognizing these heart rate ranges not only aids in evaluating the health of an infant but also underscores the overall physiological changes that occur as children age, enhancing clinicians' ability to make informed decisions during assessments.
