Nursing Elites

1. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?

• A. Evaluate the patient’s urine output.
• B. Contact the provider to order arterial blood gases.
• C. Request an order for an initial potassium bolus.
• D. Suggest a diet low in sodium and potassium.

Correct answer: A

Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.

2. The nurse notes that the only ECG for a 55-year-old male client scheduled for surgery in two hours is dated two years ago. The client reports that he has a history of 'heart trouble,' but has no problems at present. Hospital protocol requires that those over 50 years of age have a recent ECG prior to surgery. What nursing action is best for the nurse to implement?

• A. Ask the client to explain what he means by 'heart trouble.'
• B. Call for an ECG to be performed immediately.
• C. Notify surgery that the ECG is over two years old.
• D. Notify the client's surgeon immediately.

Correct answer: B

Rationale: In this scenario, the client is 55 years old with a history of 'heart trouble,' which necessitates a recent ECG before surgery as per hospital policy. The nurse should prioritize patient safety and adhere to the protocol by arranging for an ECG to be performed immediately. Option A is not the best initial action as the focus should be on obtaining the necessary test first. Option C is not the immediate action required, and option D is premature without obtaining the necessary ECG first.

3. During spring break, a young adult presents to the urgent care clinic and reports a stiff neck, a fever for the past 6 hours, and a headache. Which intervention is most important for the nurse to implement first?

• A. Initiate isolation precautions
• B. Administer an antipyretic
• C. Draw blood cultures
• D. Prepare for lumbar puncture

Correct answer: A

Rationale: The correct answer is to initiate isolation precautions. This is the priority action because the patient presents with symptoms that could be indicative of meningitis, an infectious disease that requires isolation to prevent its spread. Administering an antipyretic (Choice B) may help manage the fever but does not address the need for isolation. Drawing blood cultures (Choice C) and preparing for a lumbar puncture (Choice D) are important steps in diagnosing meningitis but should come after initiating isolation precautions to prevent potential transmission of the infection to others.

4. A nurse contacts the healthcare provider after reviewing a client’s laboratory results and noting a blood urea nitrogen (BUN) of 35 mg/dL and a creatinine of 1.0 mg/dL. For which action should the nurse recommend a prescription?

• A. Intravenous fluids
• B. Hemodialysis
• C. Fluid restriction
• D. Urine culture and sensitivity

Correct answer: A

Rationale: The normal range for BUN is 10 to 20 mg/dL, and for creatinine, it is 0.6 to 1.2 mg/dL in males and 0.5 to 1.1 mg/dL in females. Creatinine is a more specific marker for kidney function compared to BUN. In this case, the client's creatinine level is within the normal range, indicating a non-renal cause for the elevated BUN. Dehydration is a common cause of increased BUN, so the appropriate action would be to recommend intravenous fluids to address the dehydration. Fluid restriction is not indicated as the client needs hydration. Hemodialysis is not appropriate for dehydration and is typically reserved for renal failure. The laboratory results do not suggest an infection, making a urine culture and sensitivity unnecessary in this scenario.

5. A nurse reviews the laboratory findings of a client with a urinary tract infection. The laboratory report notes a “shift to the left” in the client’s white blood cell count. Which action should the nurse take?

• A. Request that the laboratory perform a differential analysis on the white blood cells.
• B. Notify the provider and start an intravenous line for parenteral antibiotics.
• C. Collaborate with the unlicensed assistive personnel (UAP) to strain the client’s urine for renal calculi.
• D. Assess the client for a potential allergic reaction and anaphylactic shock.

Correct answer: B

Rationale: A “shift to the left” in a white blood cell count indicates an increase in band cells, which is typically associated with urosepsis. In this scenario, the nurse should notify the provider and initiate IV antibiotics as a left shift is often seen in severe infections like urosepsis. Requesting a differential analysis on white blood cells would not be the immediate action needed in response to a left shift. Collaborating to strain urine for renal calculi is unrelated to the situation of a left shift in white blood cells due to urosepsis. Assessing for allergic reactions and anaphylactic shock is not the priority as a left shift is not indicative of an allergic response; it is associated with an increase in band cells, not eosinophils.
