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. 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.

3. A client is recovering from a hip replacement surgery. What is the priority nursing intervention to prevent complications?

• A. Encourage bed rest to prevent strain on the hip
• B. Assist the client with early ambulation
• C. Provide continuous passive motion therapy
• D. Administer pain medication before activity

Correct answer: B

Rationale: The correct answer is B: Assist the client with early ambulation. Early ambulation is a key intervention to prevent complications like deep vein thrombosis (DVT) and promote circulation after hip replacement surgery. It also helps with overall recovery and reduces the risk of complications related to immobility, such as muscle atrophy and pressure ulcers. Choice A is incorrect as bed rest should be avoided to prevent complications associated with immobility. Choice C, continuous passive motion therapy, is not the priority intervention immediately post-hip replacement surgery. Choice D, administering pain medication before activity, is important but not the priority intervention to prevent complications in this case.

4. A client is scheduled for a colonoscopy and has been prescribed a bowel preparation. What is the most important instruction for the nurse to provide?

• A. Eat a low-fiber diet the day before the procedure
• B. Drink clear liquids 24 hours before the procedure
• C. Take the entire bowel preparation as directed
• D. Avoid all solid foods 12 hours before the procedure

Correct answer: C

Rationale: The most important instruction for the nurse to provide to a client scheduled for a colonoscopy and prescribed a bowel preparation is to take the entire bowel preparation as directed. Completing the entire bowel preparation as prescribed is crucial to ensure the colon is properly cleansed for the colonoscopy. Incomplete bowel prep can interfere with the visualization of the colon, leading to inaccurate results. Choices A, B, and D are important but not as crucial as ensuring the complete intake of the bowel preparation for an effective procedure.

5. A client is being discharged following a cystectomy and urinary diversion. What is the most important instruction for the nurse to provide?

• A. Avoid lifting heavy objects for six weeks.
• B. Report any signs of cloudy urine output.
• C. Drink 8 glasses of water a day.
• D. Monitor for signs of infection at the surgical site.

Correct answer: B

Rationale: The most important instruction for the nurse to provide to a client following a cystectomy and urinary diversion is to report any signs of cloudy urine output. Cloudy urine may indicate infection, which is a serious concern in clients with a urinary diversion. Instructing the client to report any signs of infection immediately is crucial to prevent complications. Avoiding heavy lifting is important for postoperative recovery but not as critical as identifying a potential infection. Drinking an adequate amount of water is generally beneficial for health but not the most crucial instruction in this scenario. While monitoring for signs of infection at the surgical site is essential, cloudy urine is a more specific and immediate indicator of a potential problem in clients with urinary diversions.
