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 client has a new prescription for Omeprazole. Which of the following instructions should the nurse include?
- A. Take this medication before meals.
- B. Take this medication with food.
- C. Take this medication at bedtime.
- D. Take this medication with antacids.
Correct answer: A
Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that should be taken before meals to be most effective in reducing stomach acid production. Taking it before meals allows the medication to inhibit the proton pumps in the stomach when they are most active, leading to better control of acid secretion. Choice B is incorrect because taking Omeprazole with food may reduce its effectiveness as food can interfere with its absorption. Choice C is incorrect as Omeprazole is more effective when taken before meals. Choice D is incorrect as Omeprazole should not be taken with antacids as they can reduce its absorption.
3. Which drug undergoes extensive first-pass hepatic metabolism?
- A. Heparin
- B. Insulin
- C. Propranolol
- D. Nitroglycerin
Correct answer: C
Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
4. When a client is discharged with nitroglycerin (Nitrostat), what should the nurse include in client education?
- A. “Your chest pain should go away with one tablet.”
- B. “If your chest pain doesn’t go away after three tablets, call 911; you might be having a heart attack.”
- C. “If your chest pain doesn’t go away with one tablet, you can repeat the dose as many times as you need to.”
- D. “Be sure to call 911 before you take any tablets.”
Correct answer: B
Rationale: The correct answer instructs the client on the appropriate use of nitroglycerin. Nitroglycerin is used to relieve chest pain or angina. If the chest pain does not subside after taking one tablet, the client should take a maximum of three tablets at 5-minute intervals. If the pain persists after three tablets, it could indicate a heart attack, and emergency medical help should be sought. This education is crucial to ensure the client knows when to seek immediate medical attention.
5. When a client is prescribed hydrochlorothiazide, what adverse effect should they monitor for as instructed by the nurse?
- A. Hyponatremia
- B. Ototoxicity
- C. Hypoglycemia
- D. Hyperkalemia
Correct answer: A
Rationale: Hyponatremia is a critical adverse effect associated with hydrochlorothiazide use. This medication is a diuretic that can lead to excessive loss of sodium and water from the body, potentially causing low sodium levels and resulting in hyponatremia. Monitoring for signs and symptoms of hyponatremia, such as confusion, headache, weakness, and muscle cramps, is essential to prevent serious complications. Ototoxicity (choice B) is not a common adverse effect of hydrochlorothiazide. Hypoglycemia (choice C) and hyperkalemia (choice D) are also not typically associated with hydrochlorothiazide use.
