1. A nurse is caring for a client who has a new prescription for Metformin. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid eating foods high in potassium.
- C. Take this medication at bedtime.
- D. Take this medication every other day.
Correct answer: A
Rationale: The correct instruction for a client prescribed Metformin is to take the medication with food. Taking Metformin with meals helps reduce gastrointestinal side effects and ensures better absorption. Choice B, to avoid foods high in potassium, is not directly related to Metformin. Choice C, taking the medication at bedtime, is not a standard instruction for Metformin. Choice D, taking the medication every other day, is incorrect as Metformin is typically taken daily as prescribed.
2. 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.
3. A healthcare professional is reviewing a client's medication history and notes a new prescription for Enalapril. The healthcare professional should monitor the client for which of the following as an adverse effect of this medication?
- A. Bradycardia
- B. Hyperkalemia
- C. Hypoglycemia
- D. Hypocalcemia
Correct answer: B
Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, which leads to potassium retention. Monitoring potassium levels is essential to prevent potential complications associated with hyperkalemia. The other options, bradycardia, hypoglycemia, and hypocalcemia, are not typically associated with Enalapril use and are less likely to occur as adverse effects.
4. A client receiving chemotherapy reports nausea and vomiting. Which of the following medications should the nurse anticipate administering?
- A. Ondansetron
- B. Metoclopramide
- C. Promethazine
- D. Lorazepam
Correct answer: A
Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.
5. A healthcare provider is caring for a client who has a new prescription for Digoxin. Which of the following findings should the healthcare provider identify as a potential sign of Digoxin toxicity?
- A. Nausea
- B. Dry mouth
- C. Hypoglycemia
- D. Tinnitus
Correct answer: A
Rationale: Nausea is a potential sign of Digoxin toxicity. Along with vomiting, visual disturbances, and confusion, it can be an early indication of an overdose. Dry mouth is not typically associated with Digoxin toxicity. Hypoglycemia is a low blood sugar level and is not directly related to Digoxin toxicity. Tinnitus, a ringing in the ears, is not a common sign of Digoxin toxicity. Healthcare providers should closely monitor clients on Digoxin for symptoms like nausea to prevent serious complications.
