LPN Pharmacology Practice Test
1. A client has a new prescription for prednisone. Which of the following statements should the nurse include in teaching the client?
- A. You may experience weight gain.
- B. Increase your intake of vitamin K.
- C. Expect increased urinary output.
- D. You may have dark, tarry stools.
Correct answer: A
Rationale: The correct answer is A. Weight gain is a common side effect of prednisone. The nurse should educate the client about the possibility of weight gain and the need to monitor it closely during treatment with prednisone. Choice B is incorrect because increasing vitamin K intake is not specifically related to prednisone therapy. Choice C is incorrect as prednisone is more likely to cause fluid retention rather than increased urinary output. Choice D is incorrect as dark, tarry stools are not a common side effect of prednisone.
2. 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.
3. A client with atrial fibrillation is prescribed warfarin (Coumadin). The nurse should reinforce which dietary instruction?
- A. Avoid foods high in vitamin K.
- B. Increase intake of dairy products.
- C. Limit intake of foods high in fiber.
- D. Increase protein intake.
Correct answer: A
Rationale: The correct answer is to avoid foods high in vitamin K. Clients taking warfarin (Coumadin) should maintain a consistent intake of vitamin K to keep the medication's effectiveness stable. Foods high in vitamin K, such as leafy greens, can interfere with the anticoagulant effects of warfarin. Therefore, it is crucial for clients to avoid these foods to ensure the therapeutic effects of warfarin. Choices B, C, and D are incorrect because increasing dairy products, limiting fiber intake, or increasing protein intake do not directly impact the effectiveness of warfarin therapy and are not necessary dietary modifications for clients on this medication.
4. A nurse is assessing a client who has been taking lithium carbonate. Which of the following findings should the nurse report to the provider?
- A. Increased urination
- B. Tremors
- C. Weight gain
- D. Blurred vision
Correct answer: B
Rationale: The correct answer is B: Tremors. Tremors are a sign of lithium toxicity and should be reported immediately. Increased urination is a common side effect of lithium but not an urgent concern requiring immediate reporting. Weight gain is also a common side effect of lithium but does not indicate toxicity. Blurred vision is not typically associated with lithium toxicity; therefore, it is not the priority finding to report.
5. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?
- A. Blood glucose
- B. Serum sodium
- C. Serum potassium
- D. Blood urea nitrogen (BUN)
Correct answer: C
Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.
