Correct Answer: B

Rationale: The correct answer is B because facial swelling can indicate preeclampsia, a serious condition during pregnancy that requires immediate medical attention. Constipation (choice A), heartburn (choice C), and frequent urination (choice D) are common discomforts during pregnancy and are not typically indicative of a serious complication like preeclampsia at 32 weeks of gestation.

Correct Answer: C

Rationale: Corrected Rationale: Magnesium sulfate can cause respiratory depression, leading to a decreased respiratory rate. A respiratory rate of 10/min is abnormally low and indicates magnesium toxicity. Tachycardia (Choice A) is not typically associated with magnesium toxicity. Hyperreflexia (Choice B) is a common sign of magnesium toxicity. Polyuria (Choice D) is not a typical finding of magnesium toxicity.

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.

Correct Answer: D

Rationale: To prevent mastitis, the nurse should instruct the client to ensure that the newborn empties one breast before switching to the other. This helps to prevent milk stasis, reducing the risk of inflammation and infection. Choice A is incorrect because feeding on demand is recommended to establish a good milk supply and prevent engorgement. Choice B is incorrect as warm compresses are usually applied before feeding to promote milk flow. Choice C is incorrect because massaging the breast after feedings can actually increase the risk of mastitis by causing further irritation.

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.
