Nursing Elites

1. What is the antidote for Warfarin?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin K
• D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

2. During an admission assessment for a client with severe Aspirin toxicity, what finding should the nurse expect?

• A. Body temperature 35°C (95°F)
• B. Lung crackles
• C. Cool, dry skin
• D. Respiratory depression

Correct answer: D

Rationale: In severe Aspirin toxicity, respiratory depression can occur due to increasing respiratory acidosis. Aspirin toxicity leads to metabolic acidosis, stimulating the respiratory center in the brain to increase the respiratory rate initially. However, as the toxicity worsens, respiratory muscle fatigue and depression can occur, resulting in respiratory depression. This can lead to hypoxia, respiratory failure, and ultimately, respiratory arrest.

3. A healthcare provider is providing discharge instructions to a client who is prescribed Warfarin. Which of the following dietary instructions should the provider include?

• A. Increase your intake of leafy green vegetables.
• B. Avoid foods high in vitamin K.
• C. Increase your intake of dairy products.
• D. Avoid foods high in iron.

Correct answer: B

Rationale: The correct answer is to avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of Warfarin by counteracting its anticoagulant effects. Foods high in vitamin K, such as leafy green vegetables, should be limited in the diet of individuals taking Warfarin to maintain a consistent level of the medication's effectiveness. Choices A, C, and D are incorrect as increasing intake of leafy green vegetables (choice A) and dairy products (choice C) may increase the intake of vitamin K, which is not recommended, and avoiding foods high in iron (choice D) is not directly related to Warfarin therapy.

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

• A. Take this medication with food.
• B. Avoid foods high in potassium.
• C. Take this medication on an empty stomach.
• D. Increase your intake of sodium-rich foods.

Correct answer: C

Rationale: Captopril should be taken on an empty stomach for better absorption. The client should be instructed to take it 1 hour before or 2 hours after meals to optimize its effectiveness. Taking it with food can reduce its absorption and efficacy.

5. A client is being discharged with a new prescription for Atenolol. Which of the following instructions should the nurse include?

• A. Take this medication in the morning.
• B. Monitor your heart rate regularly.
• C. Avoid consuming foods high in potassium.
• D. Increase your fluid intake.

Correct answer: B

Rationale: The correct answer is B: 'Monitor your heart rate regularly.' Atenolol is a beta-blocker that can cause bradycardia (slow heart rate). Monitoring the heart rate regularly is crucial to promptly detect any significant decreases. This allows for timely intervention and adjustment of the medication regimen if needed, helping to prevent adverse effects associated with bradycardia. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning does not address the need for heart rate monitoring. Avoiding foods high in potassium is more relevant for medications like ACE inhibitors or potassium-sparing diuretics. Increasing fluid intake is not directly related to the use of Atenolol.
