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?

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. When teaching a client about the adverse effects of simvastatin, which of the following findings should be included as an adverse effect?

Correct answer: B

Rationale: Muscle pain should be included as an adverse effect when teaching a client about simvastatin. It can be a sign of rhabdomyolysis, a severe side effect associated with statins like simvastatin that involves muscle breakdown. Monitoring for muscle pain is crucial to prevent serious complications and ensure timely intervention. Tinnitus, diarrhea, and facial flushing are not typically associated with simvastatin use and are less common adverse effects compared to muscle pain.

3. A client has a new prescription for isoniazid. Which of the following instructions should the nurse include?

Correct answer: B

Rationale: The correct answer is to instruct the client to avoid drinking alcohol. Isoniazid can cause liver damage, and alcohol consumption can increase this risk. Therefore, it is crucial to avoid alcohol while taking isoniazid to prevent potential liver complications. Choice A is incorrect because isoniazid is typically taken with food to reduce gastrointestinal upset. Choice C is incorrect because antacids can decrease the absorption of isoniazid. Choice D is incorrect as there is no specific recommendation to increase leafy green vegetable intake when taking isoniazid.

4. A client has a new prescription for metformin. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. Metformin commonly causes gastrointestinal discomfort, and increasing fluid intake can help alleviate this side effect. Instructing the client to take the medication with food (Choice A) rather than on an empty stomach is recommended to reduce gastrointestinal side effects. Monitoring for signs of hyperglycemia (Choice B) is not directly related to metformin but rather to low blood sugar. Expecting a sweet taste in the mouth (Choice D) is not a common side effect of metformin.

5. The nurse is caring for a client diagnosed with deep vein thrombosis (DVT). Which intervention should the nurse include in the client's plan of care to prevent the complication of pulmonary embolism?

Correct answer: B

Rationale: Administering anticoagulants as prescribed is crucial in preventing the complication of pulmonary embolism in clients with deep vein thrombosis. Anticoagulants help prevent the formation of new clots and the enlargement of existing ones, thereby reducing the risk of a pulmonary embolism. Encouraging ambulation as tolerated is beneficial for preventing complications related to immobility, but it is not the primary intervention to prevent pulmonary embolism in this case. Applying cold compresses to the affected area may help with pain and swelling but does not address the prevention of pulmonary embolism. Encouraging the use of incentive spirometry is more relevant in preventing respiratory complications such as atelectasis, not specifically pulmonary embolism.
