LPN Pharmacology Practice Test
1. A healthcare provider is providing discharge instructions to a client who has a new prescription for digoxin. Which of the following instructions should the healthcare provider include?
- A. Take the medication at bedtime.
- B. Avoid taking antacids with this medication.
- C. Monitor your pulse rate daily.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: The correct answer is C: 'Monitor your pulse rate daily.' Monitoring the pulse rate daily is crucial when taking digoxin as it helps in early detection of digoxin toxicity. Digoxin can cause toxicity, which may manifest as changes in the heart rate, making monitoring the pulse rate an essential part of managing the medication. It is important for the client to be aware of their normal pulse rate and report any significant changes to their healthcare provider promptly. Choices A, B, and D are incorrect. Taking digoxin at bedtime is not a specific instruction related to monitoring its effects. Avoiding antacids is relevant for some medications, but not a key concern with digoxin. Increasing potassium-rich foods may interact with digoxin due to its effect on potassium levels, but monitoring the pulse rate is a more direct and immediate need for safety.
2. A client with a diagnosis of heart failure is being discharged. What information should the nurse emphasize to the client regarding the use of a daily weight log?
- A. Report any weight gain of more than 2 pounds in a day
- B. Weigh yourself after eating breakfast each morning
- C. Use the same scale each day to check your weight
- D. Record your weight daily and report any changes
Correct answer: A
Rationale: The correct answer is A: 'Report any weight gain of more than 2 pounds in a day.' Sudden weight gain of more than 2 pounds in a day may indicate fluid retention and worsening heart failure. This information is crucial for early intervention and monitoring of the client's condition. Weighing after eating breakfast (choice B) may not provide consistent results due to varying food and fluid intake. Using the same scale each day (choice C) ensures accuracy and consistency in weight measurements. Recording weight daily (choice D) is more frequent than necessary and may not be practical for all clients. It is essential to focus on significant weight changes to prevent unnecessary alarm or confusion.
3. The nurse is preparing to administer an intravenous dose of furosemide (Lasix) to a client with heart failure. The nurse should monitor for which potential side effect?
- A. Hypertension
- B. Hyperkalemia
- C. Hypokalemia
- D. Hypoglycemia
Correct answer: C
Rationale: Furosemide is a loop diuretic that works by promoting the excretion of water and electrolytes, including potassium. This loss of potassium can lead to hypokalemia, which can be a potential side effect of furosemide administration. Hypokalemia can result in cardiac dysrhythmias and other complications, especially in clients with heart failure who may already have compromised cardiac function. Therefore, monitoring for signs of hypokalemia, such as muscle weakness, cardiac irregularities, and fatigue, is essential when administering furosemide. Choice A, hypertension, is incorrect because furosemide is actually used to treat hypertension by reducing excess fluid in the body. Choice B, hyperkalemia, is incorrect as furosemide causes potassium loss, leading to hypokalemia. Choice D, hypoglycemia, is unrelated to the mechanism of action of furosemide and is not a common side effect associated with its administration.
4. The client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Complete blood count (CBC)
- B. Activated partial thromboplastin time (aPTT)
- C. Serum electrolytes
- D. Liver function tests
Correct answer: B
Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor the effectiveness of anticoagulant therapy, especially with heparin. A prolonged aPTT indicates effective anticoagulation, reducing the risk of further clot formation in the client with deep vein thrombosis (DVT). The other options, such as complete blood count (CBC), serum electrolytes, and liver function tests, do not directly assess the therapeutic effectiveness of anticoagulant therapy. Therefore, the correct answer is B.
5. The client with chronic stable angina is prescribed a beta blocker. The nurse is reinforcing instructions. What instruction should the nurse include?
- A. Take the medication with a meal.
- B. Report a pulse rate below 60 beats per minute.
- C. Discontinue the medication if dizziness occurs.
- D. Avoid drinking grapefruit juice.
Correct answer: B
Rationale: The correct instruction for the nurse to include is to advise the client to report a pulse rate below 60 beats per minute. Beta blockers are known to lower heart rate, and a pulse rate below 60 beats per minute may indicate bradycardia, a condition that requires medical attention. Option A, 'Take the medication with a meal,' is incorrect because beta blockers don't necessarily need to be taken with food. Option C, 'Discontinue the medication if dizziness occurs,' is incorrect because abrupt cessation of beta blockers can lead to rebound hypertension and other adverse effects. Option D, 'Avoid drinking grapefruit juice,' is unrelated to beta blockers' mechanism of action or side effects.
