Correct Answer: D

Rationale: The correct answer is D, 'All of the Above.' Magnesium sulfate should not be used in cases of fetal distress, vaginal bleeding, or cervical dilation greater than 6 cm. These conditions can be exacerbated by the administration of magnesium sulfate, leading to further complications for the client. Choice A, fetal distress, is a contraindication because magnesium sulfate can further affect the fetal heart rate. Choice B, cervical dilation greater than 6 cm, is a contraindication as magnesium sulfate can potentially suppress uterine contractions, prolonging labor. Choice C, vaginal bleeding, is a contraindication as magnesium sulfate can further increase bleeding tendencies.

Correct Answer: A

Rationale: The correct answer is A because using a water-soluble lubricant with condoms can help prevent breakage and ensure effectiveness in preventing pregnancy and sexually transmitted infections (STIs). This statement demonstrates the client's understanding of the importance of proper condom use to maximize protection. Choice B is incorrect because a diaphragm should be left in place for at least 6 hours after intercourse to ensure contraceptive effectiveness. Choice C is incorrect as oral contraceptives are known to improve acne in some cases. Choice D is incorrect because a contraceptive patch is typically replaced weekly, not monthly.

Correct Answer: B

Rationale: A weight gain of 3.6 kg (8 lb) in the first trimester is excessive and should be reported to the provider for further evaluation. Excessive weight gain in the first trimester can be a sign of potential issues that need monitoring and intervention to ensure the well-being of both the mother and the baby. Choices A, C, and D represent weight gains that are within normal ranges for the respective trimesters and do not raise immediate concerns for reporting to the provider.

Correct Answer: A

Rationale: In cases of placenta previa with active bleeding at 32 weeks of gestation, Betamethasone is prescribed to accelerate fetal lung maturity in anticipation of potential preterm delivery. This medication helps in reducing the risk of respiratory distress syndrome in the newborn, which is crucial in managing such high-risk pregnancies. Indomethacin is a nonsteroidal anti-inflammatory drug not indicated in this scenario and may be contraindicated due to its effects on platelet function and potential risk of bleeding. Nifedipine is a calcium channel blocker used for conditions like preterm labor or hypertension, not specifically for placenta previa with active bleeding. Methylergonovine is a uterotonic drug used to prevent or control postpartum hemorrhage, not indicated for placenta previa with active bleeding.

Correct Answer: C

Rationale: During labor, effective pain management is crucial. The nurse should assist the client with patterned breathing techniques to help manage pain and administer opioid analgesic medication as ordered. Providing ice chips is a comfort measure but does not directly address pain relief. Inserting a urinary catheter is not typically indicated at this stage of labor unless there are specific medical indications, such as the need to closely monitor urine output. Therefore, the correct action for the nurse to prepare to take in this scenario is to administer opioid analgesic medication.
