Nursing Elites

1. 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.

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

• A. Take the medication with food.
• B. Monitor for signs of hypokalemia.
• C. Take the medication at bedtime.
• D. Monitor for a dry cough.

Correct answer: D

Rationale: The correct answer is to monitor for a dry cough. Captopril is known to cause a persistent dry cough as a common side effect. If a dry cough develops, it should be reported to the healthcare provider promptly, as it may necessitate discontinuation of the medication. Choice A is incorrect because captopril is usually taken on an empty stomach. Choice B is incorrect as hypokalemia is not a common side effect of captopril. Choice C is incorrect as captopril is typically taken during the day and not specifically at bedtime.

3. The LPN/LVN is assisting in the care of a client who has been prescribed enoxaparin (Lovenox) for the prevention of deep vein thrombosis (DVT). Which instruction should the nurse reinforce with the client?

• A. Avoid consuming foods high in vitamin K while taking this medication.
• B. Administer the injection in the same site each time for consistency.
• C. Report any unusual bleeding or bruising to your healthcare provider.
• D. Do not take aspirin if you experience any mild pain or discomfort.

Correct answer: C

Rationale: The correct instruction for the nurse to reinforce with the client is to report any unusual bleeding or bruising to their healthcare provider. This is crucial because unusual bleeding or bruising may indicate excessive anticoagulation, a potential side effect of enoxaparin. Prompt reporting to a healthcare provider is necessary to prevent complications. Choices A, B, and D are incorrect. Choice A is not directly related to enoxaparin and vitamin K interactions. Choice B is incorrect as rotating injection sites is essential for preventing tissue damage and irritation. Choice D is also incorrect as aspirin can increase the risk of bleeding when taken with enoxaparin.

4. A healthcare professional is assessing a client who has been taking lithium carbonate for bipolar disorder. Which of the following findings should the professional report to the provider?

• A. Increased urination
• B. Tremors
• C. Weight gain
• D. Blurred vision

Correct answer: B

Rationale: Tremors are a concerning sign of lithium toxicity that indicate a potential overdose. Tremors can progress to more severe symptoms if not addressed promptly. Reporting tremors promptly allows the provider to assess the client's lithium levels, adjust the dosage, or provide appropriate interventions to prevent further complications. Increased urination, weight gain, and blurred vision are potential side effects of lithium but are not indicative of toxicity or overdose. While they should still be monitored, they are not as urgent as tremors in the context of lithium therapy.

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

• A. Take the medication on an empty stomach.
• B. Avoid drinking alcohol.
• C. Take the medication with an antacid.
• D. Increase your intake of leafy green vegetables.

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.
