Nursing Elites

1. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

2. What is the most common cause of coronary artery disease?

• A. Atherosclerosis.
• B. Hyperlipidemia.
• C. Diabetes.
• D. Smoking.

Correct answer: A

Rationale: The correct answer is Atherosclerosis. It is the primary cause of coronary artery disease, as it involves the buildup of plaque in the arteries, restricting blood flow to the heart. Hyperlipidemia (choice B) contributes to atherosclerosis by increasing cholesterol levels in the blood but is not the direct cause of coronary artery disease. Diabetes (choice C) can accelerate atherosclerosis due to high blood sugar levels, but it is not the most common cause. Smoking (choice D) is a significant risk factor for developing coronary artery disease but is not the primary cause.

3. Which of the following interventions is most appropriate for a patient with acute pancreatitis?

• A. Administering oral fluids.
• B. Administering IV fluids.
• C. Administering analgesics.
• D. Encouraging the patient to ambulate.

Correct answer: B

Rationale: The most appropriate intervention for a patient with acute pancreatitis is administering IV fluids. IV fluid administration is crucial in managing acute pancreatitis as it helps maintain hydration, correct electrolyte imbalances, and prevent shock. Administering oral fluids (Choice A) may not be sufficient to address the fluid loss and maintain hydration in these patients. While analgesics (Choice C) are important for pain management in pancreatitis, addressing hydration and shock prevention takes precedence. Encouraging the patient to ambulate (Choice D) may be beneficial in some cases for preventing complications like deep vein thrombosis, but it is not the primary intervention needed in the acute phase of pancreatitis.

4. Which of the following is the best indicator of long-term glycemic control in a patient with diabetes?

• A. Fasting blood glucose levels.
• B. Postprandial blood glucose levels.
• C. Hemoglobin A1c.
• D. Random blood glucose levels.

Correct answer: C

Rationale: The correct answer is C, Hemoglobin A1c. Hemoglobin A1c measures the average blood glucose level over the past 2-3 months, providing a reliable indicator of long-term glycemic control. Fasting blood glucose levels (choice A) only offer a snapshot of the current glucose level and can fluctuate throughout the day. Postprandial blood glucose levels (choice B) reflect glucose levels after meals but do not give a comprehensive view of long-term control. Random blood glucose levels (choice D) are taken at any time and lack the consistency needed to assess long-term glycemic control effectively. Therefore, Hemoglobin A1c is the superior choice for monitoring and managing diabetes over an extended period.

5. The nurse is caring for a client with chronic renal failure who is receiving peritoneal dialysis. Which of the following findings should be reported immediately to the physician?

• A. Clear dialysate outflow.
• B. Increased blood pressure.
• C. Cloudy dialysate outflow.
• D. Decreased urine output.

Correct answer: C

Rationale: Cloudy dialysate outflow should be reported immediately to the physician. It is indicative of peritonitis, a severe infection of the peritoneal cavity and a serious complication of peritoneal dialysis. Prompt medical attention is crucial to prevent further complications or systemic infection. Clear dialysate outflow (Choice A) is a normal finding in peritoneal dialysis. Increased blood pressure (Choice B) and decreased urine output (Choice D) are common in clients with chronic renal failure and may not require immediate reporting unless they are significantly abnormal or accompanied by other concerning symptoms.
