Nursing Elites

1. A client with chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.5 mg/dl
• D. Blood glucose of 200 mg/dl

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.

2. A client is receiving a full-strength continuous enteral tube feeding at 50 ml/hour and has developed diarrhea. The client has a new prescription to change the feeding to half strength. What intervention should the nurse implement?

• A. Add equal amounts of water and feeding to a feeding bag and infuse at 50 ml/hour
• B. Continue the full-strength feeding after decreasing the rate of infusion to 25 ml/hour
• C. Maintain the present feeding until diarrhea subsides and then begin the new prescription
• D. Withhold any further feeding until clarifying the prescription with the healthcare provider

Correct answer: A

Rationale: The correct intervention is to dilute the formula by adding equal amounts of water and feeding to a feeding bag and infusing it at 50 ml/hour. This can help alleviate the diarrhea that has developed. Diarrhea can occur as a complication of enteral tube feeding and can be due to a variety of causes, including hyperosmolar formula. Choice B is incorrect as continuing the full-strength feeding, even at a lower rate, may not address the issue of diarrhea. Choice C is incorrect because it is important to follow the new prescription to manage the diarrhea effectively. Choice D is incorrect as withholding feeding without taking appropriate action may delay necessary intervention.

3. A client with pneumonia has arterial blood gases levels at: pH 7.33; PaCO2 49 mm/Hg; HCO3 25 mEq/L; PaO2 95. What intervention should the nurse implement based on these results?

• A. Institute coughing and deep breathing protocols.
• B. Administer oxygen via nasal cannula.
• C. Prepare for intubation and mechanical ventilation.
• D. Increase IV fluids to improve hydration.

Correct answer: A

Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.

4. The nurse is caring for a client with a history of myocardial infarction who is complaining of chest pain. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Administer nitroglycerin sublingually as prescribed.
• C. Obtain an electrocardiogram (ECG).
• D. Assess the client's level of consciousness.

Correct answer: C

Rationale: Obtaining an electrocardiogram (ECG) is the first priority in assessing for ischemia or infarction in a client with chest pain and a history of myocardial infarction. This diagnostic test provides crucial information about the heart's electrical activity and helps in identifying any acute cardiac changes. Administering oxygen therapy and nitroglycerin can be important interventions, but obtaining an ECG takes precedence as it directly assesses the client's cardiac status. Assessing the client's level of consciousness is also essential, but in this scenario, assessing for cardiac indications through an ECG is the initial step.

5. An elderly male client is admitted to the urology unit with acute renal failure due to a postrenal obstruction. Which question best assists the nurse in obtaining relevant historical data?

• A. Have you had any difficulty starting your urinary stream?
• B. Do you have a history of kidney stones?
• C. How much fluid do you drink daily?
• D. Have you had any previous urinary tract infections?

Correct answer: A

Rationale: The correct answer is A: 'Have you had any difficulty starting your urinary stream?' This question is the most relevant as difficulty starting urination can indicate an obstruction, which aligns with the client's current condition of postrenal obstruction causing acute renal failure. Choice B is incorrect as a history of kidney stones may not be directly related to the current obstruction. Choice C, asking about daily fluid intake, is not specific to the current issue of postrenal obstruction. Choice D inquires about previous urinary tract infections, which are not directly related to the current acute renal failure caused by postrenal obstruction.
