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.

Correct Answer: B

Rationale: Applying counterpressure to the sacrum can help alleviate lower back pain during labor by reducing pressure on the nerves. Effleurage on the abdomen, back massage with lavender oil, and administering opioid analgesics are not specifically targeted at relieving lower back pain, making them less effective interventions in this scenario.

Correct Answer: A

Rationale: The correct answer is to instruct the client to perform rapid, shallow breathing. The urge to bear down during contractions indicates the second stage of labor, and pushing prematurely can lead to complications. Rapid, shallow breathing helps prevent pushing until the cervix is fully dilated. Choice B is incorrect because preparing for an emergency cesarean birth is not indicated based on the information provided. Choice C is incorrect as pelvic tilts are not appropriate when the client is already bearing down. Choice D is incorrect since applying counterpressure to the sacrum is not the priority when the client is showing signs of advancing labor.

Correct Answer: B

Rationale: The correct instruction for a client who is postpartum and had a cesarean birth is to not lift anything heavier than her newborn. This precaution is crucial to prevent injury to the healing incision site and allow for proper recovery. Choice A is incorrect as it implies resuming abdominal exercises in 2 weeks, which may strain the incision area. Choice C is incorrect because the client should wait longer than 1 week before driving to ensure they can perform emergency maneuvers if needed. Choice D is incorrect as resuming sexual activity in 2 weeks may put strain on the healing tissues and increase the risk of complications.
