Correct Answer: A

Rationale: Early decelerations are a benign finding that typically indicate fetal head compression, a normal response to uterine contractions. They do not require intervention as they are not associated with fetal compromise. The appropriate action for the nurse in this scenario is to continue to monitor the fetal heart rate. Repositioning the client, administering oxygen, or increasing IV fluids are not indicated responses to early decelerations and could be unnecessary or potentially harmful.

Correct Answer: D

Rationale: The nurse should report a urine output of 20 mL/hr. This finding can indicate decreased renal perfusion and possible development of preeclampsia, which is a severe complication of gestational hypertension. Inadequate urine output can suggest compromised kidney function and impaired maternal and fetal well-being. Options A, B, and C are within normal limits for a client with gestational hypertension and may not require immediate reporting to the provider.

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: 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: The correct answer is A: Headache. Methylergonovine can cause vasoconstriction, leading to headaches. It is important for the client to report this adverse effect to the provider as it may indicate a serious complication. Choices B, C, and D are incorrect because methylergonovine is not typically associated with diarrhea, nausea, or increased vaginal bleeding as common adverse effects.
