1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

2. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.

3. A client with heart failure is prescribed digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse teach the client to report?

• A. Increased appetite.
• B. Yellow or blurred vision.
• C. Weight gain.
• D. Nasal congestion.

Correct answer: B

Rationale: Yellow or blurred vision is a hallmark sign of digoxin toxicity. Digoxin toxicity can affect various body systems, but visual disturbances, such as yellow or blurred vision, are important signs that the client should report immediately. Other signs like increased appetite, weight gain, or nasal congestion are not typically associated with digoxin toxicity. Prompt reporting of visual disturbances can help prevent further complications associated with digoxin toxicity.

4. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?

• A. Serum glucose of 350 mg/dL.
• B. Serum potassium of 2.8 mEq/L.
• C. Serum sodium of 136 mEq/L.
• D. Serum bicarbonate of 20 mEq/L.

Correct answer: B

Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.

5. What should the nurse include in patient teaching for a patient prescribed ceftriaxone for bacterial pneumonia?

• A. Take the medication as prescribed.
• B. Expect urine color changes.
• C. Complete the full course of the antibiotic.
• D. Avoid dairy products during treatment.

Correct answer: C

Rationale: When educating a patient prescribed ceftriaxone for bacterial pneumonia, it is crucial to emphasize completing the full course of the antibiotic. Completing the full course helps ensure the infection is completely eradicated and reduces the risk of antibiotic resistance. Incomplete courses of antibiotics can lead to treatment failure and the development of resistant bacterial strains. Therefore, it is essential for patients to adhere to the prescribed treatment regimen to achieve optimal outcomes.
