A nurse is caring for a newborn immediately after birth. Which of the following actions by the nurse reduces evaporative heat loss by the newborn?
Maintaining ambient room temperature at 24° C (75° F).
Drying the newborn's skin thoroughly.
Preventing air drafts.
Placing the newborn on a warm surface.
The Correct Answer is B
A. Maintaining ambient room temperature at 24° C (75° F) can help prevent heat loss by keeping the environment warm, but it does not specifically address evaporative heat loss. Evaporative heat loss occurs when moisture on the skin evaporates, which is not directly controlled by ambient temperature.
B. Drying the newborn's skin thoroughly reduces evaporative heat loss by removing moisture that can evaporate and cool the skin. This action is critical immediately after birth when the newborn is wet with amniotic fluid.
C. Preventing air drafts helps reduce convective heat loss, not evaporative heat loss. Convective heat loss occurs when air moves across the skin and carries heat away.
D. Placing the newborn on a warm surface helps reduce conductive heat loss by preventing heat transfer from the baby to a cooler surface. However, this does not address evaporative heat loss, which is specifically related to moisture evaporation from the skin.

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","C","D","F"]
Explanation
Choice A rationale:
The newborn reflex called "rooting”. is characterized by turning the head and opening the mouth when the cheek or mouth area is touched. This reflex helps the newborn find the mother's breast for feeding.
Choice B rationale:
"Stepping”. is a newborn reflex where they make stepping movements when held upright with their feet touching a solid surface. This reflex is present at birth but tends to disappear after a few weeks.
Choice C rationale:
The "Moro”. reflex is also known as the startle reflex. It is elicited by a sudden loss of support or loud noise, causing the newborn to throw their arms and legs out and then bring them back in. This reflex usually disappears around 3 to 4 months of age.
Choice D rationale:
The "Babinski”. reflex is characterized by the extension of the big toe and fanning of the other toes when the sole of the foot is stroked. This reflex is present in newborns and should disappear by around 12 months of age.
Choice E rationale:
"Running”. is not a recognized newborn reflex. There is no reflex with this name related to newborns.
Choice F rationale:
The "gag”. reflex is present in newborns and helps protect the airway by causing a gagging response when the back of the throat is stimulated.
