LPN Pharmacology Practice Questions
1. When teaching a client with a new prescription for spironolactone, which instruction should the nurse include?
- A. Increase your intake of potassium-rich foods.
- B. Avoid consuming grapefruit juice.
- C. Take the medication with food.
- D. Monitor for signs of hyperkalemia.
Correct answer: D
Rationale: The correct answer is to instruct the client to monitor for signs of hyperkalemia when taking spironolactone since it is a potassium-sparing diuretic. Hyperkalemia is a potential adverse effect due to the medication's mechanism of action. Advising the client to increase potassium-rich foods (Choice A) would be incorrect as it can further elevate potassium levels, which could lead to hyperkalemia. Avoiding grapefruit juice (Choice B) is not directly related to spironolactone use. Though taking the medication with food (Choice C) can help reduce gastrointestinal upset, it is not the most critical instruction when initiating spironolactone therapy.
2. A client has a new prescription for phenytoin. Which of the following instructions should the nurse include?
- A. Take the medication with a full glass of water.
- B. Avoid consuming dairy products.
- C. Take the medication on an empty stomach.
- D. Expect a metallic taste in your mouth.
Correct answer: B
Rationale: The correct instruction for a client prescribed phenytoin is to avoid consuming dairy products. Dairy products can reduce the absorption of phenytoin. Taking the medication with a full glass of water (Choice A) is generally a good practice for oral medications but is not specifically required for phenytoin. Taking the medication on an empty stomach (Choice C) can lead to gastrointestinal upset, so it is not recommended for phenytoin. Expecting a metallic taste in the mouth (Choice D) is a possible side effect of phenytoin but is not a crucial instruction for the client to follow.
3. A 24-year-old man seeks medical attention for complaints of claudication in the arch of the foot. The nurse also notes superficial thrombophlebitis of the lower leg. What should the nurse check the client for next?
- A. Smoking history
- B. Recent exposure to allergens
- C. History of recent insect bites
- D. Familial tendency toward peripheral vascular disease
Correct answer: A
Rationale: In this case, the nurse should check the client's smoking history next. Smoking is a significant risk factor for peripheral vascular disease, leading to the development of thrombophlebitis and claudication. It is important to assess this risk factor as it can significantly impact the client's vascular health and the progression of their current symptoms. Choices B, C, and D are incorrect because they are not directly related to the symptoms described by the client. Recent exposure to allergens or insect bites would typically present with different symptoms, and familial tendency toward peripheral vascular disease is not the immediate concern in this case.
4. The nurse is caring for a client receiving anticoagulant therapy. Which instruction should the nurse reinforce with the client to prevent bleeding complications?
- A. Use a soft-bristle toothbrush and electric razor.
- B. Increase your intake of vitamin K-rich foods.
- C. Take aspirin if you have a headache.
- D. Avoid using ice packs for injuries.
Correct answer: A
Rationale: The correct instruction to prevent bleeding complications in a client on anticoagulant therapy is to use a soft-bristle toothbrush and an electric razor. These implements help reduce the risk of bleeding by being gentle on the skin and reducing the chances of cuts or abrasions that could lead to bleeding in individuals on anticoagulants. Choice B is incorrect because increasing intake of vitamin K-rich foods can interfere with the action of anticoagulants. Choice C is incorrect as aspirin is a blood thinner and can increase the risk of bleeding when combined with anticoagulant therapy. Choice D is incorrect as ice packs can help reduce bleeding and swelling in injuries, but in a client on anticoagulant therapy, it is important to avoid potential trauma to the skin that could lead to bleeding.
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.
