A nurse is caring for a newborn who is at 34 weeks of gestation, weighs 1,550 g, and has nasal flaring, intercostal retractions, expiratory grunting, and mild cyanosis. The nurse should place the newborn in an incubator for which of the following reasons?
The newborn's temperature control mechanism is immature.
Heat increases the flow of oxygen to the newborn's extremities.
The newborn has a small body surface for his weight.
Heat facilitates the drainage of mucus for a premature newborn.
The Correct Answer is A
Choice A rationale:
Placing the newborn in an incubator is essential because the newborn's temperature control mechanism is immature. Premature infants have an underdeveloped thermoregulatory system, making them susceptible to heat loss and cold stress. An incubator provides a controlled, warm environment to maintain the newborn's body temperature within the normal range (around 36.5°C to 37.5°C or 97.7°F to 99.5°F).
Choice B rationale:
Heat increasing the flow of oxygen to the newborn's extremities is not a valid reason for placing the newborn in an incubator. Oxygenation is primarily influenced by respiratory and circulatory mechanisms, not external heat.
Choice C rationale:
The newborn's small body surface area for his weight is not directly related to the need for an incubator. Premature infants have a higher surface area to weight ratio, making them more prone to heat loss, but this is not the primary reason for using an incubator.
Choice D rationale:
Heat facilitating the drainage of mucus is not a reason for placing the newborn in an incubator. Proper positioning and suctioning are used to manage mucus in premature infants, but incubators are primarily for temperature regulation.

Correct Answer is C
Explanation
Choice A rationale:
Wearing a supportive bra can actually help to manage engorgement, so it's not recommended to avoid wearing one during the day.
Choice B rationale:
Cold compresses are typically applied after feeding to reduce swelling, not before. Applying them before might hinder the milk let-down reflex.
Choice C rationale:
Frequent feeding can help to alleviate engorgement by ensuring that the breasts are being emptied regularly.
Choice D rationale:
Stopping breastfeeding until finishing antibiotics is not advisable, as it can lead to decreased milk supply and potential issues with engorgement. Antibiotics prescribed by a healthcare provider are usually safe to take while breastfeeding, and interrupting breastfeeding can exacerbate the engorgement problem. This choice is not appropriate for managing breast engorgement and is therefore incorrect.
Correct Answer is A
Explanation
Choice A rationale:
An apical pulse of 130/min in a newborn is within the normal range. The normal heart rate for a newborn is generally between 110 to 160 beats per minute (bpm). As the newborn's heart rate falls within this range, the nurse should document it as an expected finding and continue routine monitoring.
Choice B rationale:
Calling the neonatologist to assess the newborn for an apical pulse of 130/min is not warranted as it is a normal finding. The nurse should only notify the neonatologist if there are abnormal vital signs or concerning clinical signs.
Choice C rationale:
Asking another nurse to verify the heart rate is unnecessary in this scenario. The nurse can independently measure the apical pulse and document the finding as long as it falls within the normal range for newborns.
Choice D rationale:
Preparing the newborn for transport to the Neonatal Intensive Care Unit (NICU) is not indicated for a normal apical pulse rate. Transporting a newborn to the NICU is typically reserved for critical or unstable conditions. In this case, the normal heart rate of 130/min does not warrant NICU transport.
