Correct Answer: B

Rationale: The correct answer is deep tendon reflexes. Monitoring deep tendon reflexes is crucial to assess for magnesium toxicity during therapy for preeclampsia. Magnesium sulfate can lead to neuromuscular blockade, reflected by decreased or absent deep tendon reflexes. Assessing bowel sounds (choice A) is important for gastrointestinal function but is not directly related to magnesium sulfate therapy. Oxygen saturation (choice C) is vital for respiratory status but is not specifically linked to magnesium sulfate administration. Fluid balance (choice D) is essential but does not directly correlate with monitoring for complications of magnesium sulfate therapy in the context of preeclampsia.

Correct Answer: C

Rationale: The correct answer is C: Infusion reaction. Vancomycin can cause infusion reactions like 'Red Man Syndrome,' which involves rashes, flushing, tachycardia, and hypotension. Hepatotoxicity (choice A) is not a common adverse effect of vancomycin. Constipation (choice B) is not typically associated with vancomycin use. Immunosuppression (choice D) is not a direct adverse effect of vancomycin therapy.

Correct Answer: D

Rationale: The correct answer is D: Productive cough. Nitroglycerin therapy can lead to adverse effects such as tolerance, orthostatic hypotension, and headache. However, it is not known to cause a productive cough. Tolerance may develop over time, requiring dose adjustments. Orthostatic hypotension can occur due to vasodilation effects, leading to a sudden drop in blood pressure when changing positions. Headache is a common side effect due to vasodilation of cranial blood vessels. Productive cough is not a recognized adverse effect associated with transdermal nitroglycerin therapy.

Correct Answer: A

Rationale: Tachycardia is the correct answer as it is an adverse effect of levothyroxine. Levothyroxine is a medication used to treat hypothyroidism by supplementing the body with thyroid hormone. Tachycardia, or a fast heart rate, can indicate an overdosage or increased sensitivity to levothyroxine. Bradycardia, slow heart rate, weight loss, and increased appetite are not typically associated with adverse effects of levothyroxine. Bradycardia may actually be a symptom of untreated hypothyroidism.

Correct Answer: B

Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.
