Correct Answer: C

Rationale: The correct answer is C. Drinking orange juice before the nonstress test can increase fetal movement, which is essential for an accurate reading. Choice A is incorrect because oxytocin is not typically administered during a nonstress test. Choice B is incorrect as fasting is not required before this test. Choice D is incorrect as a full bladder is not necessary for a nonstress test.

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: A

Rationale: A respiratory rate of 10/min is significantly low and indicates potential magnesium toxicity, which can lead to respiratory depression. This finding should be reported to the provider immediately for further evaluation and management. Urine output of 30 mL/hr is within the expected range during magnesium sulfate therapy and does not require immediate reporting. Deep tendon reflexes 2+ are a normal finding and do not indicate any immediate concerns. The client reporting feeling warm is a common side effect of magnesium sulfate and does not require immediate reporting unless accompanied by other symptoms.

Correct Answer: C

Rationale: The correct answer is C. Drinking orange juice before the nonstress test can increase fetal movement, which is essential for an accurate reading. Choice A is incorrect because oxytocin is not typically administered during a nonstress test. Choice B is incorrect as fasting is not required before this test. Choice D is incorrect as a full bladder is not necessary for a nonstress test.

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.
