Nursing Elites

1. 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.

2. The nurse is caring for four clients: Client A, who has emphysema and an oxygen saturation of 94%; Client B, with a postoperative hemoglobin of 8.7 g/dL; Client C, newly admitted with a potassium level of 3.8 mEq/L; and Client D, scheduled for an appendectomy with a white blood cell count of 15,000/mm3. What intervention should the nurse implement?

• A. Increase Client A's oxygen to 4 liters per minute via nasal cannula.
• B. Determine if Client B has two units of packed cells available in the blood bank.
• C. Ask the dietitian to add a banana to Client C's breakfast tray.
• D. Inform Client D that surgery is likely to be delayed until the infection is treated.

Correct answer: D

Rationale: A high white blood cell count, as seen in Client D, indicates infection, which may require postponing surgery to treat the infection adequately. It is crucial to address the underlying infection before proceeding with the appendectomy to prevent complications and ensure a successful surgical outcome.

3. A healthcare professional is educating a group of recent nursing graduates about their risks for contracting hepatitis B. What preventative measure should the professional promote?

• A. Immunization
• B. Chronic tonsillitis
• C. Consumption of a vitamin-rich diet
• D. Annual vitamin K injections

Correct answer: A

Rationale: The correct preventative measure to promote for preventing hepatitis B infection is immunization. Healthcare workers, including nurses, are at risk of exposure to hepatitis B, and vaccination is crucial in preventing infection. Immunization, along with adherence to standard precautions such as using personal protective equipment, proper hand hygiene, and safe needle practices, plays a vital role in protecting healthcare workers from contracting hepatitis B.

4. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

5. In acute pancreatitis, a client experiencing severe abdominal pain should have which enzyme level closely monitored?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase levels should be closely monitored. Elevated serum amylase levels are a key diagnostic marker for acute pancreatitis, aiding in the assessment and management of the patient's condition. Monitoring serum sodium, calcium, or potassium levels is not typically associated with acute pancreatitis and would not provide relevant information for this specific condition.
