A nurse is reinforcing teaching with the parents of a newborn about caring for the umbilical cord stump. Which of the following instructions should the nurse include?

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.

Choice A: Warm the bottle in the microwave.

• Rationale: Warming bottles in the microwave is not recommended. Microwaving can cause uneven heating, creating hot spots in the milk or formula that can burn the baby's mouth. Instead, bottles should be warmed by placing them in a container of warm water or using a bottle warmer.

Choice B: Store prepared bottles in the refrigerator.

• Correct
• Rationale: Prepared bottles of formula should be stored in the refrigerator to prevent bacterial growth. Formula should be used within 24 hours of preparation when properly stored in the refrigerator.

Choice C: Discard unused formula in used bottle after 2 hours.

• Correct
• Rationale: Any unused formula that has been in contact with the baby’s mouth should be discarded after 2 hours due to the risk of bacterial contamination. Bacteria from the baby's saliva can grow in the leftover formula.

Choice D: Never prop a bottle.

• Correct
• Rationale: Bottles should never be propped up and left in the baby’s mouth. This practice increases the risk of choking, ear infections, and tooth decay. Caregivers should always hold the bottle and the baby during feedings.

Choice E: Formula is available in three forms.

• Correct
• Rationale: Formula is available in three forms: powdered, concentrated liquid, and ready-to-feed. Parents should be informed of these options so they can choose the most convenient or appropriate form based on their needs.
