LPN Pharmacology Assessment A
1. A client with chronic heart failure is being discharged with a prescription for digoxin (Lanoxin). Which instruction should the nurse reinforce?
- A. Take the medication at the same time each day.
- B. Avoid foods high in potassium.
- C. Skip a dose if you feel well.
- D. Take the medication on an empty stomach.
Correct answer: A
Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm. Choices B, C, and D are incorrect because avoiding potassium-rich foods, skipping doses when feeling well, and taking the medication on an empty stomach are not relevant or appropriate instructions for a client prescribed digoxin.
2. A client with hypertension is prescribed enalapril (Vasotec). The nurse should monitor the client for which adverse effect?
- A. Hypotension
- B. Hypertension
- C. Tachycardia
- D. Hyperglycemia
Correct answer: A
Rationale: Enalapril, an ACE inhibitor, can lead to hypotension, particularly following the initial dose or dosage escalation. This effect is due to the medication's mechanism of action in dilating blood vessels, which can result in lowered blood pressure. Monitoring for hypotension is crucial to prevent complications such as dizziness, lightheadedness, or fainting in clients taking enalapril. Choices B, C, and D are incorrect because enalapril does not typically cause hypertension, tachycardia, or hyperglycemia as adverse effects.
3. A client with a history of coronary artery disease is prescribed atorvastatin (Lipitor). What side effect should the nurse instruct the client to immediately report?
- A. Muscle pain or tenderness
- B. Constipation
- C. Dry mouth
- D. Drowsiness
Correct answer: A
Rationale: The correct answer is 'Muscle pain or tenderness.' This can be a sign of rhabdomyolysis, a serious side effect of statins like atorvastatin (Lipitor). Rhabdomyolysis is a condition in which muscle breakdown releases a protein that can damage the kidneys. Therefore, it is crucial for the client to report any muscle pain or tenderness immediately to prevent further complications. Choices B, C, and D are incorrect because they are not typically associated with atorvastatin (Lipitor) use or indicative of a serious adverse effect that requires immediate reporting.
4. A client has a new prescription for metformin. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor for signs of hypoglycemia.
- C. Increase fluid intake.
- D. Expect a metallic taste in the mouth.
Correct answer: C
Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration can also help reduce the risk of kidney problems associated with metformin use. Choices A, B, and D are incorrect. While it's generally recommended to take metformin with food to reduce stomach upset, monitoring for signs of hypoglycemia is more relevant for other antidiabetic medications, and a metallic taste in the mouth is not a common side effect of metformin.
5. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should monitor which laboratory test to determine the effectiveness of the therapy?
- A. Prothrombin time (PT) and international normalized ratio (INR)
- B. Activated partial thromboplastin time (aPTT)
- C. Complete blood count (CBC)
- D. Fibrinogen level
Correct answer: A
Rationale: To monitor the effectiveness of warfarin therapy in a client with atrial fibrillation, the nurse should assess the Prothrombin time (PT) and international normalized ratio (INR) levels. These tests help determine the clotting ability of the blood and ensure that the client's anticoagulation levels are within the therapeutic range, reducing the risk of bleeding or clotting complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy. Complete blood count (CBC) (Choice C) provides information about the cellular components of blood but does not directly assess the effectiveness of warfarin therapy. Fibrinogen level (Choice D) is not typically used to monitor warfarin therapy; it reflects the level of fibrinogen in the blood, which is involved in the clotting process.
