1. 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.
2. A healthcare provider is caring for a client who is prescribed Furosemide. Which of the following laboratory values should the healthcare provider monitor?
- A. Serum potassium
- B. Serum calcium
- C. Serum sodium
- D. Serum magnesium
Correct answer: A
Rationale: Furosemide is a loop diuretic that can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Monitoring serum potassium levels is crucial to prevent complications such as cardiac arrhythmias. Therefore, the healthcare provider should closely monitor the client's serum potassium levels when they are prescribed Furosemide. While monitoring other electrolytes like sodium and magnesium may also be important in certain situations, the priority for a client prescribed Furosemide is to monitor serum potassium levels due to the risk of hypokalemia.
3. A healthcare professional in a provider's office is reviewing the medical record of a client who is pregnant and is at her first prenatal visit. Which of the following immunizations may the healthcare professional administer safely to this client?
- A. Varicella vaccine
- B. Rubella vaccine
- C. Inactivated influenza vaccine
- D. Measles vaccine
Correct answer: C
Rationale: The correct answer is C, the inactivated influenza vaccine. During pregnancy, the Centers for Disease Control and Prevention (CDC) recommend the inactivated influenza vaccine as safe for pregnant individuals. This vaccination is crucial to protect both the pregnant person and their developing baby from influenza-related complications. It is essential to avoid live vaccines, such as varicella (chickenpox), rubella, and measles vaccines during pregnancy due to the theoretical risk of harm to the fetus. Choices A, B, and D are incorrect because live vaccines are generally contraindicated during pregnancy.
4. A client has a new prescription for Sucralfate to treat a duodenal ulcer. Which of the following instructions should be included?
- A. Take the medication with meals.
- B. Swallow the tablet whole.
- C. Take the medication 1 hour before meals.
- D. Chew the tablet before swallowing.
Correct answer: C
Rationale: The correct instruction for taking Sucralfate is to take it 1 hour before meals. This timing allows the medication to coat the stomach lining, providing a protective barrier against stomach acid, which aids in healing the duodenal ulcer. Option A is incorrect as it contradicts the correct timing for taking Sucralfate. Option B is not necessary as it does not pertain to how the medication should be taken in relation to meals. Option D is incorrect as chewing the tablet before swallowing is not the correct administration method for Sucralfate.
5. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Take this medication at bedtime.
- C. Take this medication on an empty stomach.
- D. Take this medication with antacids.
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption. By taking Levothyroxine on an empty stomach, the client ensures optimal absorption and effectiveness of the medication.
