Correct Answer: D

Rationale: The correct answer is D: Initiate phototherapy. Phototherapy is the primary treatment for a newborn with hyperbilirubinemia, as it helps to break down excess bilirubin in the skin. Administering glucose water (choice A) is not indicated for treating hyperbilirubinemia. Feeding the newborn formula (choice B) or offering sterile water (choice C) will not directly address the elevated bilirubin levels in the newborn.

Correct Answer: C

Rationale: The correct answer is C: 'Thin with loose skin.' Postmature newborns are typically thin with loose skin due to prolonged gestation. This may result from placental insufficiency, leading to reduced subcutaneous fat stores. Choices A, B, and D are incorrect. Soft, flexible ear cartilage (choice A) is a normal finding in newborns. Smooth soles without creases (choice B) are also typical in newborns. Vernix caseosa covering the body (choice D) is a protective, waxy coating found on newborns, which may be present in postmature infants as well.

Correct Answer: B

Rationale: The correct instruction for the nurse to provide is to advise the client to apply breast milk to the nipples after feedings. Breast milk has healing properties and can help soothe sore nipples. Option A is incorrect because avoiding the use of a breast pump does not directly address nipple soreness. Option C is incorrect as feeding the newborn less frequently can lead to engorgement and further complications. Option D is incorrect as using a nipple shield during feedings may not address the underlying issue of soreness and can sometimes even worsen the situation.

Correct Answer: C

Rationale: The correct answer is C. During a glucose tolerance test, the client is required to drink a glucose solution, and blood samples are taken at specific intervals, typically over a period of 1 to 3 hours. In this case, the nurse should inform the client to expect the test to take about 1 hour. Choices A, B, and D are incorrect because there is no specific instruction to eat a low-carbohydrate diet for 3 days before the test, fast for 12 hours before the test, or limit fluid intake to water before the test in a standard glucose tolerance test.

Correct Answer: A

Rationale: A respiratory rate of 70/min in a newborn is above the expected range and may indicate respiratory distress, which should be reported to the provider. Choice B, vernix caseosa covering the skin, is a normal finding in newborns and does not require reporting. Choice C, milia on the bridge of the nose, is also a common finding in newborns and does not require immediate reporting. Choice D, acrocyanosis of the extremities, is a common finding within the first few hours of life in newborns and typically resolves on its own, so it does not need to be reported.
