Correct Answer: A

Rationale: A bluish-brown marking across the lower back is more commonly seen in newborns with dark skin. These markings are known as Mongolian spots and are benign. They are not related to hyperbilirubinemia, forceps marks, or trauma during delivery. Choice B is incorrect because hyperbilirubinemia presents as jaundice, not as a bluish-brown marking. Choice C is incorrect because forceps marks would have a different appearance and location. Choice D is incorrect as Mongolian spots are not related to prolonged birth or trauma during delivery.

Correct Answer: B

Rationale: The correct answer is B. A continuous high-pitched cry is a characteristic sign of neonatal abstinence syndrome, indicating withdrawal from drugs. Choices A, C, and D are incorrect because decreased muscle tone, sleeping for 2 to 3 hours after a feeding, and mild tremors when disturbed are not specific indicators of neonatal abstinence syndrome.

Correct Answer: B

Rationale: The correct answer is B: 'Missed miscarriage.' In a missed miscarriage, fetal and placental tissues are retained in the uterus after fetal demise, which matches the scenario described in the question. This situation often requires medical or surgical intervention to remove the remaining products of conception and prevent complications. 'Incomplete miscarriage' (Choice A) typically involves partial expulsion of products of conception, 'Inevitable miscarriage' (Choice C) indicates that miscarriage is in progress and cannot be stopped, and 'Complete miscarriage' (Choice D) signifies that all products of conception have been expelled from the uterus.

Correct Answer: C

Rationale: Sunken fontanels should be prioritized for reporting as they indicate dehydration, which is a critical concern in infants undergoing phototherapy. Dehydration can lead to serious complications, making it essential for the nurse to promptly inform the charge nurse for appropriate intervention and management. Conjunctivitis, bronze skin discoloration, and maculopapular skin rash are important findings to note, but in this scenario, sunken fontanels take precedence due to the potential severity of dehydration in infants.

Correct Answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.
