How does a baby's pulse and respiration rate compare to that of an adult?

Slower than an adult
Equal to an adult
Faster than an adult
Irregular compared to an adult

The correct answer is: Faster than an adult

A baby's pulse and respiration rate is generally faster than that of an adult due to several physiological factors. Infants have a higher metabolic rate, which requires their hearts to pump more blood and their lungs to oxygenate more quickly. The typical resting heart rate for newborns ranges from 120 to 160 beats per minute, while adults usually have a resting heart rate between 60 to 100 beats per minute. Similarly, the normal respiratory rate for infants can be about 30 to 60 breaths per minute, whereas adults typically breathe 12 to 20 times per minute. These differences are essential for understanding growth and developmental benchmarks in pediatrics and highlight the body's adjusting mechanisms in infants who are in a rapid growth phase. Recognizing the normal ranges for infants compared to adults is crucial for medical assistants when monitoring vital signs during patient assessments.
