A nurse is collecting data from a newborn 1 hr after delivery. Which of the following respiratory rates is within the expected reference range for a newborn?
22/min.
100/min.
48/min.
110/min.
The Correct Answer is C
Choice A rationale:
A respiratory rate of 22/min would be abnormally low for a newborn. The expected reference range for newborns is around 30-60 breaths per minute.
Choice B rationale:
A respiratory rate of 100/min would be abnormally high for a newborn. Such a high respiratory rate may indicate respiratory distress or other underlying issues and requires further evaluation.
Choice C rationale:
A respiratory rate of 48/min falls within the expected reference range for a newborn, which is around 30-60 breaths per minute. This rate suggests that the newborn's respiratory system is functioning within the normal range.
Choice D rationale:
A respiratory rate of 110/min would be abnormally high for a newborn. As mentioned earlier, the expected reference range for newborns is around 30-60 breaths per minute, making this rate concerning and necessitating further assessment.

Correct Answer is B
Explanation
Choice A rationale:
Newborns do not show interest in eating while crying. Crying is usually an indication of distress or hunger and not a state where they are interested in eating.
Choice B rationale:
Newborns are most interested in eating when they are in an "alert”. state. During this state, the baby is awake, calm, and attentive, making it an ideal time for feeding.
Choice C rationale:
In the "drowsy”. state, newborns may be sleepy and less interested in eating. They might feed less effectively in this state.
Choice D rationale:
"Active alert”. is a state where the newborn is awake, attentive, and active. While they may be interested in their surroundings, they may also be easily distracted during feeding.
Correct Answer is ["A","B","D"]
Explanation
Choice A rationale:
The normal temperature range for a newborn measured axillary (armpit) is 97.7-99.3°F (36.5- 37.4°C). This is a crucial vital sign to monitor, as any significant deviation from this range could indicate an underlying issue requiring further evaluation.
Choice B rationale:
The newborn's heart rate varies with their activity level. While asleep, it is around 100 bpm, and when awake, it is 120-160 bpm. During crying or agitation, it can go up to 180 bpm.
Monitoring the heart rate is essential, as any abnormal values might indicate cardiac or other health problems.
Choice D rationale:
The normal respiratory rate for a newborn is 30-60 breaths per minute. Respiratory rate is a critical parameter to monitor as rapid or slow breathing could be a sign of respiratory distress or other respiratory conditions.
Choice C rationale:
Blood pressure is not routinely assessed in newborns, as it is challenging to obtain accurate readings due to their small size and physiology. Instead, other vital signs are relied upon for assessment.
Choice E rationale:
The head circumference is not included in the normal vital sign ranges. However, monitoring head circumference is crucial during infancy to track brain growth and development.
