LPN Pharmacology Practice Test
1. A client has a new prescription for clozapine. Which of the following instructions should the nurse include?
- A. You should have your white blood cell count checked regularly.
- B. You should take this medication on an empty stomach.
- C. You should avoid eating foods high in tyramine.
- D. You should avoid taking this medication with milk.
Correct answer: A
Rationale: The correct answer is A: 'You should have your white blood cell count checked regularly.' Clozapine can lead to agranulocytosis, a serious condition characterized by a low white blood cell count. Regular monitoring of the white blood cell count is crucial to detect this adverse effect early and prevent serious complications. Choices B, C, and D are incorrect because taking clozapine on an empty stomach, avoiding foods high in tyramine, or avoiding taking the medication with milk are not specific instructions related to the potential adverse effect of agranulocytosis associated with clozapine.
2. When assessing a client receiving total parenteral nutrition (TPN), which laboratory value is most important for the nurse to monitor regularly?
- A. Albumin
- B. Calcium
- C. Glucose
- D. Alkaline phosphatase
Correct answer: C
Rationale: The most important laboratory value to monitor regularly in clients receiving total parenteral nutrition (TPN) is glucose. TPN solutions contain high concentrations of glucose, which can lead to hyperglycemia. Monitoring glucose levels is crucial to detect and prevent hyperglycemia, a common complication associated with TPN administration. Albumin (Choice A) levels are not typically affected by TPN administration. Calcium (Choice B) and alkaline phosphatase (Choice D) are not directly impacted by TPN and are not the primary values to monitor in TPN therapy.
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. A client has a new prescription for lisinopril. Which of the following findings should be reported to the provider by the nurse?
- A. Weight gain
- B. Dry cough
- C. Hypokalemia
- D. Increased appetite
Correct answer: B
Rationale: The correct answer is B - Dry cough. Lisinopril is known to cause a persistent dry cough as a common side effect. This adverse reaction can be bothersome to the client and may necessitate discontinuation of the medication. Weight gain, hypokalemia, and increased appetite are not typically associated with lisinopril and would not be as concerning as a dry cough when assessing for adverse effects.
5. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should reinforce which instruction?
- A. Avoid foods high in vitamin K.
- B. Increase intake of dairy products.
- C. Limit intake of high-fiber foods.
- D. Avoid protein-rich foods.
Correct answer: A
Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.
