Nursing Elites

1. A client admitted to the hospital with a diagnosis of acute pancreatitis has blood drawn for several serum laboratory tests. Which of the following serum amylase values, noted by the nurse reviewing the results, would be expected in this client at this time?

• A. 48 units/L
• B. 97 units/L
• C. 150 units/L
• D. 395 units/L

Correct answer: D

Rationale: The correct answer is D: "395 units/L." The normal serum amylase range is 25 to 151 units/L. In acute pancreatitis, the amylase level is greatly increased, typically exceeding the upper limit of the normal range. Choices A, B, and C fall within the normal range of serum amylase levels and would not be expected in a client with acute pancreatitis.

2. A client with a chest tube attached to a closed drainage system has undergone a chest x-ray, which revealed that the affected lung is fully reexpanded. The nurse anticipates that the next assessment of the chest tube system will reveal:

• A. No fluctuation in the water seal chamber
• B. Continuous bubbling in the water seal chamber
• C. Increased drainage in the collection chamber
• D. Continuous gentle suction in the suction control chamber

Correct answer: A

Rationale: When the client's lung is fully reexpanded, the chest tube drainage system will no longer be actively draining, and there will be no fluctuation in the water seal chamber. Option B, continuous bubbling in the water seal chamber, indicates an air leak in the system, which is not expected when the lung is fully expanded. Option C, increased drainage in the collection chamber, would not be expected when the lung is reexpanded as there should be minimal to no drainage. Option D, continuous gentle suction in the suction control chamber, would not be appropriate when the lung is fully reexpanded and the chest tube is typically on a water seal system at this point to promote reexpansion and prevent air from entering the pleural space.

3. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?

• A. 2 mg/dL
• B. 18 mg/dL
• C. 25 mg/dL
• D. 35 mg/dL

Correct answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.

4. The client with chronic renal failure who is on a low-sodium diet should avoid which of the following foods?

• A. Fresh fruits.
• B. Canned soups.
• C. Lean meats.
• D. Whole grain bread.

Correct answer: B

Rationale: Canned soups are high in sodium, which can lead to fluid retention and hypertension in clients with chronic renal failure who are on a low-sodium diet. Fresh fruits, lean meats, and whole grain bread are generally lower in sodium and can be included in a low-sodium diet. Lean meats provide essential protein, fresh fruits offer vitamins and minerals, and whole grain bread provides fiber, making them suitable choices for individuals with chronic renal failure.

5. The nurse is preparing to administer digoxin to a patient who is newly admitted to the intensive care unit. The nurse reviews the patient’s admission electrolytes and notes a serum potassium level of 2.9 mEq/L. Which action by the nurse is correct?

• A. Administer the digoxin and monitor the patient’s electrocardiogram closely.
• B. Hold the digoxin dose and notify the provider of the patient’s lab values.
• C. Request an order for an intravenous bolus of potassium.
• D. Request an order for oral potassium supplements.

Correct answer: B

Rationale: In the scenario presented, the patient has a low serum potassium level, which can predispose the patient to digoxin toxicity. It is essential for the nurse to hold the digoxin dose and promptly notify the healthcare provider of the abnormal lab values. Option A is incorrect because administering digoxin without addressing the low potassium level can potentiate toxicity. Option C is inappropriate as potassium should not be given as an IV bolus, especially in the case of hypokalemia. Option D is incorrect because oral potassium supplements may not be sufficient for rapidly correcting severe hypokalemia in an acute care setting.
