Correct Answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. In a client receiving magnesium sulfate for preeclampsia, decreased deep tendon reflexes indicate magnesium toxicity. Magnesium toxicity can lead to respiratory depression and other serious complications, requiring immediate intervention. Choices B, C, and D are incorrect because increased blood pressure, tachypnea, and hyperreflexia are not typical findings associated with magnesium toxicity.

Correct Answer: A

Rationale: The correct question the nurse should ask the client who is 38 weeks pregnant with herpes simplex virus is 'Do you have any active lesions?' This is crucial because active herpes lesions may necessitate a cesarean delivery to prevent neonatal infection. Choice B, 'Have your membranes ruptured?' is related to assessing for the rupture of membranes, not specific to the client's herpes infection. Choice C, 'How far apart are your contractions?' is related to monitoring labor progress. Choice D, 'Are you positive for beta strep?' is related to group B streptococcus screening, which is important but not the priority in this scenario.

Correct Answer: A

Rationale: Tingling in the fingers and around the mouth is a sign of hypocalcemia, which can occur after thyroid surgery due to accidental damage to the parathyroid glands. Hypocalcemia is common after thyroidectomy due to potential parathyroid damage. Calcium gluconate is the appropriate intervention to treat hypocalcemia. Providing a high-protein diet or administering levothyroxine are not indicated for hypocalcemia. Applying a warm compress to the client's neck would not address the underlying issue of hypocalcemia.

Correct Answer: B

Rationale: The correct answer is B: 'Take with a glass of orange juice.' Ferrous sulfate should be taken with orange juice (vitamin C) to enhance the absorption of iron. Taking it with milk (choice A) is not recommended as calcium can interfere with iron absorption. Taking it at bedtime (choice C) or with meals (choice D) may lead to decreased absorption due to interactions with other food or medications.

Correct Answer: B

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods. Furosemide, a loop diuretic, can lead to potassium loss, which may cause hypokalemia. Increasing potassium intake can help prevent this electrolyte imbalance. Choice A is incorrect because furosemide is usually taken in the morning to prevent sleep disturbances due to increased urination. Choice C is incorrect because a decrease in urine output could indicate a problem and should be reported immediately. Choice D is incorrect because furosemide is used to reduce swelling in the body, including the lower extremities, so expecting swelling is not appropriate.
