1. A client is prescribed Propylthiouracil (PTU) for the treatment of Graves' disease. Which adverse effect should the client be instructed to report?
- A. Sore throat.
- B. Drowsiness.
- C. Urinary retention.
- D. Heat intolerance.
Correct answer: A
Rationale: The correct answer is A: Sore throat. A sore throat and fever can indicate agranulocytosis, a serious adverse effect of PTU that can lead to a decreased white blood cell count. This condition requires immediate medical attention to prevent complications. Choice B, drowsiness, is not typically associated with PTU and is not a common adverse effect that needs to be reported. Choice C, urinary retention, is not a typical adverse effect of PTU; therefore, it is not the correct answer. Choice D, heat intolerance, is a symptom commonly seen in hyperthyroidism, which PTU is used to treat, so it is not an adverse effect that needs to be specifically reported.
2. A healthcare provider is providing teaching to a client who has a new prescription for metronidazole. The healthcare provider should instruct the client to avoid which of the following?
- A. Dairy products
- B. Alcohol
- C. Leafy green vegetables
- D. Grapefruit juice
Correct answer: B
Rationale: The correct answer is B: Alcohol. Clients should avoid alcohol while taking metronidazole due to the risk of a disulfiram-like reaction. This reaction can cause symptoms like flushing, headache, nausea, and vomiting when alcohol is consumed while on metronidazole. Dairy products, leafy green vegetables, and grapefruit juice do not have significant interactions with metronidazole. Dairy products do not interfere with metronidazole absorption; leafy green vegetables are safe to consume as they do not affect metronidazole metabolism, and grapefruit juice is not contraindicated with metronidazole.
3. Which drug classes are NOT typically used to treat angina?
- A. Calcium channel blockers
- B. Organic nitrates
- C. Alpha blockers
- D. Beta blockers
Correct answer: C
Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.
4. A hospitalized client receiving IV heparin for a deep-vein thrombosis begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?
- A. Vitamin K1
- B. Atropine
- C. Protamine
- D. Calcium gluconate
Correct answer: C
Rationale: In this scenario, the client is experiencing a serious complication of heparin therapy, likely due to heparin-induced thrombocytopenia. Protamine is the antidote for heparin and can reverse its anticoagulant effects. It is essential to administer protamine promptly to counteract the effects of heparin and manage the bleeding. Vitamin K1 is used to reverse the effects of warfarin, not heparin. Atropine is used to treat bradycardia or some types of poisoning. Calcium gluconate is used to manage hyperkalemia or calcium channel blocker toxicity, not to reverse heparin's effects.
5. A client in the operating room received a dose of Succinylcholine, leading to muscle rigidity and a sudden rise in body temperature. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: C
Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.
