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 action the nurse should take first when observing variable decelerations in the fetal heart rate is to reposition the client from side to side. Variable decelerations are often caused by umbilical cord compression, and repositioning the client can relieve pressure on the cord. Administering oxygen, increasing the IV infusion rate, and notifying the provider can be appropriate actions but repositioning the client takes priority in addressing variable decelerations.

Correct Answer: A

Rationale: Abdominal cramping during breastfeeding is common due to the release of oxytocin. Ibuprofen, an analgesic, is suitable for relieving discomfort. Administering oxytocin is unnecessary and may exacerbate the cramping. Placing a warm compress may not address the underlying cause of the cramping. Changing positions may provide temporary relief but does not address the cause of the cramping.

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: 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.
