Nursing Elites

1. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?

• A. Hemoglobin
• B. Prothrombin time (PT)
• C. Bleeding time
• D. Activated partial thromboplastin time (aPTT)

Correct answer: B

Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A client has been prescribed an anticoagulant for atrial fibrillation. Which of the following instructions should the nurse include?

• A. Take the medication with food to prevent nausea.
• B. Avoid activities that may cause injury.
• C. Monitor your heart rate daily before taking the medication.
• D. Avoid alcohol while taking this medication.

Correct answer: B

Rationale: The correct instruction for a client prescribed an anticoagulant for atrial fibrillation is to avoid activities that may cause injury. Anticoagulants increase the risk of bleeding, so it is important to prevent situations that could lead to injury or trauma. Choice A is incorrect because anticoagulants are not typically affected by food intake. Choice C is not necessary for all anticoagulant medications, and heart rate monitoring is more relevant for other conditions. Choice D is not directly related to the action of anticoagulants and is not a priority instruction for this medication.

3. A client has a new prescription for Valsartan, and a nurse is providing discharge teaching. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid potassium-rich foods.
• C. Expect to feel drowsy.
• D. Monitor your blood pressure daily.

Correct answer: D

Rationale: Monitoring blood pressure daily is crucial for clients taking Valsartan, an angiotensin II receptor blocker, to ensure effective management of hypertension. Valsartan helps lower blood pressure by relaxing blood vessels, and regular monitoring helps track the medication's effectiveness and any potential side effects. Choices A, B, and C are incorrect because Valsartan does not need to be taken with food, avoiding potassium-rich foods is not specifically required for this medication, and feeling drowsy is not a common side effect of Valsartan.

4. What is a severe adverse effect of warfarin?

• A. Bleeding
• B. Arrhythmias
• C. Blurred vision
• D. Bradycardia

Correct answer: A

Rationale: A severe adverse effect of warfarin is bleeding. Warfarin is an anticoagulant medication that works by inhibiting blood clotting factors, which can lead to an increased risk of bleeding. Excessive bleeding can occur internally or externally, and it is crucial for individuals taking warfarin to be aware of this potential complication and seek medical attention if they experience any signs of bleeding. Arrhythmias, blurred vision, and bradycardia are not typically associated with warfarin use, making them incorrect choices.

5. A client is starting a new prescription for furosemide. Which of the following instructions should the nurse include?

• A. Weigh yourself daily.
• B. Limit sodium intake.
• C. Increase potassium intake.
• D. Avoid potassium-rich foods.

Correct answer: A

Rationale: The correct instruction to include when starting furosemide is to weigh yourself daily. Daily weighing helps monitor for fluid loss or retention, which is crucial when taking a diuretic like furosemide. Choices B, C, and D are incorrect because although monitoring sodium intake and potassium levels are important when taking furosemide, the most immediate and direct way to assess the medication's effectiveness and the body's response is through daily weight monitoring.
