Nursing Elites

1. A client with heart failure is receiving digoxin. Which finding should indicate to the nurse that the client is experiencing digoxin toxicity?

• A. Constipation
• B. Blurred vision
• C. Bradycardia
• D. Dry cough

Correct answer: C

Rationale: Bradycardia is a hallmark sign of digoxin toxicity. Digoxin, a medication used to treat heart conditions, can lead to toxicity manifesting as bradycardia. Bradycardia occurs due to the drug's effect on slowing down the heart rate excessively. Constipation (Choice A) is not typically associated with digoxin toxicity. Blurred vision (Choice B) is more commonly linked to visual disturbances caused by digoxin, but it is not a defining sign of toxicity. Dry cough (Choice D) is not a recognized symptom of digoxin toxicity. It is crucial for the nurse to recognize the early signs of digoxin toxicity to prevent serious complications and provide appropriate interventions promptly.

2. When teaching a client who has a new prescription for metformin, which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Monitor for signs of hyperglycemia.
• C. Increase your fluid intake.
• D. Expect a metallic taste in your mouth.

Correct answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration helps reduce the risk of gastrointestinal upset and ensures the medication is well-tolerated. Option A is generally true for metformin but is not as essential as maintaining proper hydration. Option B is important but not directly related to starting metformin. Option D is incorrect as a metallic taste in the mouth is not typically associated with metformin.

3. The nurse is caring for a client with a diagnosis of myocardial infarction (MI) and is assisting the client in completing the diet menu. Which beverage does the nurse instruct the client to select from the menu?

• A. Tea
• B. Cola
• C. Coffee
• D. Lemonade

Correct answer: D

Rationale: Lemonade is the correct choice as it is caffeine-free, unlike tea, cola, and coffee, which contain caffeine that can potentially affect the client's heart rhythm. Caffeine can increase heart rate and blood pressure, which may not be advisable for a client with a recent MI. Tea, cola, and coffee should be avoided due to their caffeine content, which can have stimulant effects on the heart and may not be beneficial for a client recovering from a myocardial infarction.

4. The client with Raynaud's phenomenon is being taught by the nurse about preventing episodes. Which instruction should the nurse reinforce?

• A. Wear gloves in cold weather.
• B. Avoid caffeine and chocolate.
• C. Increase intake of vitamin C.
• D. Use a heating pad for warmth.

Correct answer: A

Rationale: The correct answer is A: 'Wear gloves in cold weather.' Wearing gloves in cold weather is essential for preventing vasoconstriction and subsequent episodes of Raynaud's phenomenon. Cold temperatures can trigger vasospasms in individuals with Raynaud's, and wearing gloves helps maintain warmth and prevent the constriction of blood vessels in the extremities, reducing the likelihood of an episode. Choices B, C, and D are incorrect because while avoiding caffeine and chocolate, increasing vitamin C intake, and using a heating pad for warmth can be beneficial for overall health, they are not specifically targeted at preventing Raynaud's phenomenon episodes triggered by cold weather.

5. A client with atrial fibrillation is prescribed warfarin (Coumadin). The nurse should reinforce which dietary instruction?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of foods high in fiber.
• D. Increase protein intake.

Correct answer: A

Rationale: The correct answer is to avoid foods high in vitamin K. Clients taking warfarin (Coumadin) should maintain a consistent intake of vitamin K to keep the medication's effectiveness stable. Foods high in vitamin K, such as leafy greens, can interfere with the anticoagulant effects of warfarin. Therefore, it is crucial for clients to avoid these foods to ensure the therapeutic effects of warfarin. Choices B, C, and D are incorrect because increasing dairy products, limiting fiber intake, or increasing protein intake do not directly impact the effectiveness of warfarin therapy and are not necessary dietary modifications for clients on this medication.
