Final answer:
The normal heart rate for a child aged 1-6 is typically 80-120 beats per minute, which decreases from infancy to adolescence as part of natural growth and development.
Step-by-step explanation:
The normal heart rate for a child between the ages of 1-6 is generally 80-120 beats per minute (Option B). While a newborn's resting heart rate may be 120 bpm, the heart rate gradually decreases until young adulthood. For infants under 1 year, a normal respiratory rate is between 30 and 60 breaths per minute, reducing to 18 to 30 by the age of 10, and reaching an adult-like rate of 12 to 18 by adolescence. Changes in heart rates and respiratory rates are part of the natural progression as a child grows and are monitored by medical professionals to ensure healthy development.
