Nursing Elites

1. Which lab value is critical for monitoring warfarin therapy?

• A. Monitor INR
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

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

• A. Take this medication in the evening before bed.
• B. Take this medication on an empty stomach.
• C. Take this medication with a full glass of milk.
• D. Take this medication with an antacid if you experience indigestion.

Correct answer: B

Rationale: The correct instruction when taking levothyroxine is to take it on an empty stomach. This enhances absorption and ensures the medication's effectiveness. Taking it with food or other substances, such as milk or antacids, can interfere with its absorption. Therefore, choices A, C, and D are incorrect.

3. A client requests the creation of a living will. Which of the following actions should the nurse take?

• A. Schedule a meeting between the hospital ethics committee and the client
• B. Evaluate the client's understanding of life-sustaining measures
• C. Determine the client's preferences about post-mortem care
• D. Request a conference with the client's family

Correct answer: B

Rationale: The correct action for the nurse to take when a client requests the creation of a living will is to evaluate the client's understanding of life-sustaining measures. This step is crucial to ensure that the client is well-informed about their options before making decisions regarding their future care. Scheduling a meeting with the hospital ethics committee (choice A) may not be necessary at this stage and could overwhelm the client. Determining the client's preferences about post-mortem care (choice C) is not directly related to creating a living will. Requesting a conference with the client's family (choice D) may be important later but is not the initial step in this situation.

4. A client with a history of heart failure is receiving furosemide. Which of the following laboratory values should the nurse monitor?

• A. Sodium 140 mEq/L
• B. Calcium 9.0 mg/dL
• C. Potassium 3.2 mEq/L
• D. Chloride 100 mEq/L

Correct answer: C

Rationale: The correct answer is C: Potassium 3.2 mEq/L. A potassium level of 3.2 mEq/L is below the normal range and should be monitored in clients receiving furosemide due to the risk of hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. Choices A, B, and D are not directly impacted by furosemide therapy in the same way as potassium levels, making them less relevant for monitoring in this scenario.

5. A client with heart failure is being educated by a nurse about fluid restrictions. Which of the following instructions should the nurse include?

• A. Limit your fluid intake to 3 liters per day.
• B. Increase your fluid intake to 5 liters per day.
• C. Avoid drinking more than 1 liter of fluid per day.
• D. You can drink as much fluid as you want during meals.

Correct answer: C

Rationale: The correct answer is C: "Avoid drinking more than 1 liter of fluid per day." Clients with heart failure are typically advised to limit their fluid intake to around 1 liter per day to prevent fluid overload, which can worsen their condition. Choices A, B, and D are incorrect because they suggest fluid intakes that are higher than the recommended limit, which could lead to fluid retention and exacerbate heart failure symptoms.
