The nurse works in a postnatal nursery and is required by hospital policy to perform a gestational age assessment on specified neonates. On which neonate is the nurse most likely to perform this assessment?

Correct Answer: A

Rationale: The correct answer is A: The neonate with a birth weight of 4,100 g. Gestational age assessment is typically done based on birth weight, as it is a more accurate indicator than other factors like labor duration or exposure to medications. A birth weight of 4,100 g is considered to be indicative of a full-term baby, which is usually around 37-42 weeks gestation. Other choices like B (neonate born at 37 weeks) could be a premature or post-term baby, C (born after 18-hour labor) doesn't directly indicate gestational age, and D (exposed to oxytocin) is not a reliable indicator of gestational age. Weight is a key factor in determining gestational age, making choice A the most appropriate for the nurse to perform the assessment.

Correct Answer: C

Rationale: The correct answer is C because offering a sucrose-dipped pacifier during the nerve block procedure can help manage the newborn's pain by providing comfort and distraction through the sweet taste and sucking motion. Sucrose has been shown to have analgesic effects in newborns. Choice A is incorrect as a tourniquet is not recommended for circumcision. Choice B may help with calming but not specifically with pain management. Choice D is incorrect as numbing with ice before the nerve block may not be effective in providing adequate pain relief during the procedure.

Correct Answer: D

Rationale: The correct answer is D because the nurse does not mention the term "hyperbilirubinemia" to the mother. Instead, the nurse focuses on explaining the high level of unconjugated bilirubin causing jaundice. A: The nurse likely mentioned that the blood test does not indicate a pathological disease to reassure the mother that jaundice is a common condition in newborns. B: The nurse would have explained that the newborn's liver converts bilirubin to a water-soluble substance as part of the discussion on how bilirubin is processed in the body. C: An abundance of RBCs and their short lifespan contributing to jaundice would be relevant information that the nurse would provide to explain the underlying causes of the condition.

Correct Answer: A

Rationale: The correct answer is A because avoiding bottles helps maintain the baby's preference for breastfeeding, leading to a higher likelihood of continuing beyond 6 months. Using formula for every other feeding (choice B) introduces a different feeding method, potentially reducing breastfeeding duration. Offering water or formula after breastfeeding (choice C) can reduce the baby's interest in breastfeeding exclusively. A satisfied baby for 4 hours after feeding (choice D) does not necessarily indicate a longer breastfeeding duration as other factors like feeding frequency play a role.

Correct Answer: B

Rationale: The correct answer is B (100 to 110 kcal/kg). Full-term formula-fed infants need around 100 to 110 kcal/kg per day for optimal growth and development. This amount is tailored to meet their energy requirements and support proper weight gain. Choices A, C, and D are incorrect because they either fall below or exceed the recommended range for infants. Option A (50 to 75 kcal/kg) is too low, which may lead to inadequate energy intake. Option C (120 to 140 kcal/kg) and Option D (150 to 200 kcal/kg) are too high, potentially causing excessive weight gain or metabolic issues. Therefore, option B is the most suitable and balanced choice for meeting the energy needs of formula-fed infants.
