Final answer:
Observing an infant's respiratory rate for a full 60 seconds is important to accurately assess their respiratory health and detect any potential issues that may require medical attention.
Step-by-step explanation:
An infant's respiratory rate should be observed for a full 60 seconds because it can be an important indicator of disease or distress. The respiratory rate is the total number of breaths that occur each minute. By observing the rate for a full minute, healthcare professionals can accurately assess if the infant's respiratory rate falls within the normal range for their age. This can help identify any potential health issues that may require medical attention.
The normal respiratory rate of a child decreases from birth to adolescence. For infants under 1 year of age, the normal respiratory rate is between 30 and 60 breaths per minute. By adolescence, the normal rate is similar to that of adults, ranging from 12 to 18 breaths per minute. Observing the respiratory rate for a full 60 seconds allows healthcare professionals to accurately determine if the infant's rate falls within the normal range or if further medical intervention is needed.
