Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

2. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.

3. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Administer a loop diuretic as prescribed.
• C. Administer intravenous morphine as prescribed.
• D. Obtain an arterial blood gas (ABG) sample.

Correct answer: A

Rationale: Administering oxygen therapy is the priority intervention for a client with chronic heart failure presenting with shortness of breath and crackles in the lungs. Oxygen therapy helps improve oxygenation, which is crucial in managing respiratory distress. Loop diuretics (Choice B) may be indicated to manage fluid overload in heart failure but are not the immediate priority in this case. Administering morphine (Choice C) is not the first-line intervention for shortness of breath in heart failure and should be considered after addressing oxygenation and underlying causes. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not the initial action needed to address the client's acute respiratory distress.

4. A client with a history of chronic alcoholism is admitted with confusion, ataxia, and diplopia. Which nursing intervention is a priority for this client?

• A. Monitor for signs of alcohol withdrawal.
• B. Administer thiamine as prescribed.
• C. Provide a quiet environment to reduce confusion.
• D. Initiate fall precautions.

Correct answer: B

Rationale: The correct answer is to administer thiamine as prescribed. This intervention is a priority for clients with chronic alcoholism to prevent Wernicke's encephalopathy, a serious complication of thiamine deficiency. Monitoring for signs of alcohol withdrawal (choice A) is important but not the priority in this scenario. Providing a quiet environment (choice C) may be beneficial but does not address the immediate need to prevent Wernicke's encephalopathy. Initiating fall precautions (choice D) is also important but not the priority compared to administering thiamine to prevent a life-threatening condition.

5. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be closely monitored?

• A. Serum sodium level
• B. Serum potassium level
• C. Serum creatinine level
• D. Serum glucose level

Correct answer: B

Rationale: In a client with left-sided heart failure, monitoring serum potassium levels is crucial. This helps in assessing kidney function and fluid balance. Elevated potassium levels can result from impaired kidney function, which is common in heart failure. Monitoring sodium levels (choice A) is important in heart failure but not specifically related to left-sided heart failure. Serum creatinine (choice C) reflects kidney function but is not the most critical value to monitor in this case. Serum glucose level (choice D) is important but not the priority when assessing left-sided heart failure.
