Nursing Elites

1. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

2. A client is receiving IV fluid therapy for dehydration. Which assessment finding indicates that the client's fluid status is improving?

• A. Urine output increases to 50 mL/hour
• B. Client reports feeling more thirsty
• C. Blood pressure decreases from 120/80 to 110/70
• D. Heart rate increases from 80 to 100 beats per minute

Correct answer: A

Rationale: An increase in urine output is a positive sign that the client's hydration status is improving. It indicates that the kidneys are functioning well and that fluid therapy is effective. Increased urine output helps to eliminate excess fluid and waste products from the body. Choices B, C, and D are incorrect. Feeling more thirsty (choice B) is a sign of dehydration, not improvement. A decrease in blood pressure (choice C) and an increase in heart rate (choice D) are not typically indicative of improving fluid status during IV fluid therapy for dehydration.

3. The nurse is providing care for a client with a percutaneous endoscopic gastrostomy (PEG) tube. Which intervention should the nurse implement to prevent complications associated with the tube?

• A. Elevate the head of the bed to 15 degrees during feedings
• B. Aspirate gastric contents before administering medications
• C. Clamp the tube between feedings
• D. Flush the tube with water before and after feedings

Correct answer: D

Rationale: Flushing the PEG tube with water before and after feedings helps prevent clogging and maintains tube patency. Proper flushing is essential for avoiding complications related to tube blockages. Elevating the head of the bed is important for preventing aspiration during and after feedings, not specifically related to PEG tube complications. Aspirating gastric contents before administering medications is not routinely recommended for PEG tube care. Clamping the tube between feedings can lead to tube occlusion and is not a standard practice in PEG tube care.

4. The nurse has received funding to design a health promotion project for African American women who are at risk for developing breast cancer. Which resource is most important in designing this program?

• A. Participation of community leaders in planning the program
• B. Latest research on breast cancer risk factors
• C. Partnership with local healthcare providers
• D. Health surveys of African American women in the community

Correct answer: A

Rationale: The most important resource in designing a health promotion project for African American women at risk for breast cancer is the participation of community leaders in planning the program. Involving community leaders helps ensure that the program is culturally relevant, addresses the specific needs of the target population, and fosters trust and engagement. While the latest research on breast cancer risk factors, partnership with local healthcare providers, and health surveys of African American women are valuable resources, they are not as crucial as community involvement for tailoring the program effectively.

5. After an older client receives treatment for drug toxicity, the healthcare provider prescribes a 24-hour creatinine clearance test. Before starting the urine collection, the nurse noted that the client's serum creatinine was 0.3 mg/dL. Which action should the nurse implement?

• A. Check the client's urine output hourly
• B. Instruct the client to increase fluid intake
• C. Notify the healthcare provider of the results
• D. Start the 24-hour urine collection

Correct answer: C

Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.
