When reinforcing teaching with new parents on bathing a newborn, a nurse observes a bluish-brown marking across the newborn's lower back. Which of the following statements should the nurse make concerning the variation?

Correct Answer: A

Rationale: The correct answer is A: This is more commonly seen in newborns who have dark skin. The bluish-brown marking described is likely a Mongolian spot, a common birthmark in darker-skinned infants. It is not related to hyperbilirubinemia (jaundice), forceps marks, or birth trauma. Mongolian spots are benign and typically fade over time. This statement is correct as it addresses the specific characteristic of the marking and its association with dark skin pigmentation in newborns.

Correct Answer: D

Rationale: The correct answer is D: Covering the newborn's head with a cap. This is the highest priority as newborns are at risk for heat loss due to their large head surface area. By covering the newborn's head with a cap, heat loss can be minimized, helping to maintain the baby's body temperature. This is crucial for the newborn's overall well-being and to prevent complications such as hypothermia. Initiating breastfeeding (A) is important for newborn nutrition but can be delayed slightly without immediate harm. Performing the initial bath (B) can also wait as it is not as urgent as maintaining the newborn's temperature. Giving a vitamin K injection (C) is important for blood clotting but can be done after ensuring the baby's temperature is stable.

Correct Answer: C

Rationale: Rationale: C is correct because keeping the nipple full of formula throughout the feeding helps prevent the baby from swallowing air, reducing the risk of gas and colic. A is incorrect because burping should be done mid-feeding. B is incorrect because newborns should be held in an upright position while feeding to prevent choking. D is incorrect because unused formula should be discarded within 1-2 hours, not refrigerated.

Correct Answer: C

Rationale: The correct answer is C. Cleaning the penis with each diaper change is crucial for proper circumcision care to prevent infection. This statement shows understanding of the teaching as it emphasizes the importance of keeping the area clean. A: The circumcision healing within a couple of days is incorrect as it usually takes about 1-2 weeks. B: Not removing the yellow mucus can lead to infection, so this is an incorrect statement. D: Giving a tub bath within a couple of days can increase the risk of infection, so this statement is incorrect.

Correct Answer: D

Rationale: The correct answer is D because a baby who is postmature may have dry, cracked, and peeling skin, leading to a leathery appearance due to prolonged exposure to amniotic fluid. This occurs as the protective vernix caseosa diminishes over time. Choice A is incorrect because excess baby fat is not a typical characteristic of postmaturity. Choice B is incorrect as flat areola without breast buds is not a common feature of postmaturity. Choice C is incorrect as the ability to easily move heels to ears is a sign of flexibility and does not specifically relate to postmaturity.
