A client with severe preeclampsia is receiving magnesium sulfate intravenously. Which action should the nurse take when toxicity occurs?

Correct Answer: C

Rationale: When toxicity from magnesium sulfate occurs, the nurse should administer calcium gluconate IV as it is the antidote for magnesium sulfate toxicity. Positioning the client supine may not address the toxicity issue. Administering dextrose 5% is not the appropriate intervention for magnesium sulfate toxicity. Methylergonovine is used to manage postpartum hemorrhage and is not indicated for magnesium sulfate toxicity.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to discontinue the oxytocin infusion. Contractions occurring every 45 seconds indicate uterine hyperstimulation, which can pose risks to both the client and the fetus. By stopping the oxytocin infusion, the nurse can help prevent further complications. Choices B, C, and D are incorrect because increasing, decreasing, or maintaining the oxytocin infusion can exacerbate the uterine hyperstimulation and increase the risks associated with it.

Correct Answer: C

Rationale: A flat anterior fontanel indicates effective treatment for dehydration in infants. Dehydration often causes sunken fontanels, so when the anterior fontanel becomes flat, it suggests that rehydration has occurred. Sunken anterior fontanel (Choice A) is a sign of dehydration, not effective treatment. Tenting skin turgor (Choice B) is also a sign of dehydration, indicating poor skin turgor. Hyperpnea (Choice D) is increased depth and rate of breathing and is not directly related to the hydration status of the client.

Correct Answer: C

Rationale: The correct answer is C: 'Rice with black beans.' Plant-based proteins such as beans are recommended for clients with hepatic encephalopathy to reduce ammonia production from animal proteins. Cottage cheese (choice A), tuna salad (choice B), and a three-egg omelet (choice D) are high in animal proteins, which can contribute to increased ammonia levels in hepatic encephalopathy, making them less suitable dietary choices for these clients.

Correct Answer: B

Rationale: The correct answer is B: Wear a dosimeter badge. When caring for a client with a sealed radiation implant, the nurse should wear a dosimeter badge to monitor radiation exposure. This badge helps measure the amount of radiation the nurse is exposed to during care. Choice A is incorrect because removing dirty linens after double-bagging is not directly related to managing radiation exposure. Choice C is incorrect as there is no specific time limit on visitors mentioned in the context of a sealed radiation implant. Choice D is incorrect as there is no evidence supporting the need for family members to stay a specific distance away from the client.
