1. Which medication is commonly prescribed for patients with atrial fibrillation?

• A. Warfarin
• B. Digoxin
• C. Aspirin
• D. Lisinopril

Correct answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

2. Which lab value is critical for patients on warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.

3. A nurse is caring for a client who is 1 day postoperative following a below-the-knee amputation. Which of the following actions should the nurse take?

• A. Keep the residual limb flat on the bed
• B. Elevate the residual limb on a pillow
• C. Place the client in a prone position for 30 minutes 4 times a day
• D. Keep the residual limb dependent

Correct answer: C

Rationale: The correct action the nurse should take is to place the client in a prone position for 30 minutes four times a day. This position helps prevent contractures after an amputation by stretching the hip flexors and preventing shortening of the residual limb. Keeping the residual limb flat on the bed (Choice A) may lead to contractures. Elevating the residual limb on a pillow (Choice B) can also cause contractures and hinder proper healing. Keeping the residual limb dependent (Choice D) is not recommended as it does not promote proper positioning and circulation.

4. A nurse is preparing to administer digoxin to a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Heart rate of 60/min
• D. Sodium 140 mEq/L

Correct answer: C

Rationale: The correct answer is C: Heart rate of 60/min. A heart rate of 60/min is borderline bradycardia, which can be a sign of digoxin toxicity. Digoxin can cause bradycardia, so any further decrease in heart rate should be reported promptly to the healthcare provider. Choices A, B, and D are within the normal range and not specifically related to potential digoxin toxicity, so they do not require immediate reporting.

5. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be elevated?

• A. Serum albumin.
• B. Ammonia.
• C. Bilirubin.
• D. Prothrombin time.

Correct answer: B

Rationale: The correct answer is B: Ammonia. In clients with cirrhosis, impaired liver function can lead to elevated levels of ammonia in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a condition characterized by altered mental status. Serum albumin (Choice A) is typically decreased in cirrhosis due to the liver's reduced synthetic function. Bilirubin (Choice C) levels can be elevated in liver disease but may not always be the most specific marker for cirrhosis. Prothrombin time (Choice D) is prolonged in cirrhosis due to impaired liver synthesis of clotting factors.
