LPN Pharmacology Practice Questions
1. The client with atrial fibrillation is receiving warfarin (Coumadin). Which laboratory test should be monitored 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: Monitoring Prothrombin time (PT) and international normalized ratio (INR) is crucial when a client is on warfarin therapy. These tests assess the clotting ability of the blood and help determine the appropriate dosage of warfarin to prevent complications such as bleeding or clotting events. PT and INR values within the therapeutic range indicate the effectiveness of warfarin in managing atrial fibrillation. Choice B, activated partial thromboplastin time (aPTT), is not typically used to monitor warfarin therapy; it is more commonly used to assess the effectiveness of heparin therapy. Choice C, complete blood count (CBC), does not directly assess the anticoagulant effect of warfarin. Choice D, fibrinogen level, is not a primary test for monitoring warfarin therapy; it is more relevant in assessing conditions like disseminated intravascular coagulation.
2. How should a healthcare provider care for a patient with a nasogastric (NG) tube?
- A. Check tube placement and assess for signs of aspiration
- B. Flush the tube with water regularly to maintain patency
- C. Monitor for bowel sounds and administer medications
- D. Administer medications through the tube
Correct answer: A
Rationale: When caring for a patient with a nasogastric (NG) tube, it is crucial to check the tube placement and assess for signs of aspiration. This ensures that the tube is correctly positioned and that the patient is not at risk of complications such as aspiration pneumonia. Choice B is incorrect as flushing the tube with water regularly is not a standard practice and may not be appropriate for all patients. Choice C is incorrect as monitoring for bowel sounds is not directly related to NG tube care, and administering medications is not the primary focus of caring for the tube itself. Choice D is incorrect because administering medications through the NG tube is a specific action that may be taken based on a healthcare provider's order, not a general care guideline for the NG tube.
3. When providing dietary instructions to a client with cirrhosis, which dietary restriction is important for the nurse to emphasize?
- A. Low-protein diet
- B. Low-sodium diet
- C. High-fiber diet
- D. High-calcium diet
Correct answer: B
Rationale: A low-sodium diet is crucial for clients with cirrhosis to manage fluid retention and ascites. Excessive sodium intake can worsen fluid accumulation in the body, leading to complications. By restricting sodium intake, the client can help reduce fluid retention and maintain better overall health. Therefore, emphasizing a low-sodium diet is essential in the dietary management of cirrhosis. Choices A, C, and D are not the primary focus for cirrhosis management. While protein restriction may be necessary in advanced stages of liver disease, it is not the main dietary concern in cirrhosis. High-fiber and high-calcium diets are generally beneficial for overall health but are not specifically emphasized in cirrhosis management.
4. A patient with systemic lupus erythematosus (SLE) is prescribed hydroxychloroquine. What is the most important instruction the nurse should give?
- A. Report any vision changes immediately.
- B. Take the medication with milk.
- C. Avoid high-fat foods.
- D. Increase intake of green leafy vegetables.
Correct answer: A
Rationale: The correct instruction for a patient prescribed hydroxychloroquine, especially in the context of systemic lupus erythematosus (SLE), is to report any vision changes immediately. Hydroxychloroquine can potentially cause retinal damage, so prompt reporting and ophthalmologic evaluation are essential in preventing irreversible eye complications. Choices B, C, and D are incorrect because they do not address the significant adverse effect of hydroxychloroquine on vision. Taking the medication with milk, avoiding high-fat foods, or increasing intake of green leafy vegetables are not relevant to the primary concern of monitoring for visual changes.
5. A client with heart failure is on a fluid restriction. What should the nurse include in the discharge teaching?
- A. Encourage the client to drink more water to stay hydrated
- B. Monitor the client's weight daily
- C. Avoid drinking water after 6 PM
- D. Monitor fluid intake only during meals
Correct answer: B
Rationale: The correct answer is B: 'Monitor the client's weight daily.' In clients with heart failure on fluid restriction, monitoring daily weight is crucial to track fluid balance. This allows healthcare providers to assess if the client is retaining excess fluid, a common issue in heart failure. Choices A, C, and D are incorrect. Encouraging the client to drink more water contradicts the fluid restriction; avoiding drinking water after 6 PM is not specific to managing fluid restriction; and monitoring fluid intake only during meals does not provide a comprehensive assessment of fluid balance throughout the day.
