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. The nurse is providing care for a client with heart failure who is prescribed furosemide. Which laboratory value should the nurse monitor closely?

• A. Calcium level
• B. Sodium level
• C. Magnesium level
• D. Potassium level

Correct answer: D

Rationale: The correct answer is D: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. While calcium, sodium, and magnesium levels are important in various conditions and treatments, they are not the primary electrolyte affected by furosemide.

3. After receiving a report on an inpatient acute care unit, which client should the nurse assess first?

• A. Client with pneumonia who has a fever of 101.5°F
• B. Client who underwent knee surgery and needs dressing change
• C. Client with a bowel obstruction due to a volvulus experiencing abdominal rigidity
• D. Client with diabetes requesting insulin

Correct answer: C

Rationale: The correct answer is C. Abdominal rigidity in a client with a bowel obstruction could indicate peritonitis, a serious complication requiring immediate attention. Volvulus, a twisting of the intestine, can lead to bowel ischemia and necrosis. Clients with pneumonia (choice A) may need assessment and treatment for infection, but it is not as immediately life-threatening as a bowel obstruction. A client who underwent knee surgery (choice B) needing a dressing change can typically wait for assessment compared to a potential surgical emergency. Similarly, a client with diabetes requesting insulin (choice D) may require attention to maintain blood glucose levels, but it is not as urgent as a suspected bowel obstruction with possible peritonitis.

4. A client with acute pancreatitis is admitted with severe, piercing abdominal pain and an elevated serum amylase. Which additional information is the client most likely to report to the nurse?

• A. Pain radiates to the back
• B. Nausea and vomiting without relief
• C. Abdominal pain decreases when lying supine
• D. Abdominal pain is worse after eating

Correct answer: D

Rationale: The correct answer is D. In acute pancreatitis, abdominal pain typically worsens after eating due to the stimulation of the pancreas to release enzymes that irritate the inflamed tissues. Pain relief when lying supine is uncommon and usually exacerbates discomfort. While nausea and vomiting are common symptoms, they are not as indicative of changes in pain intensity. Pain radiating to the back is characteristic but does not specifically relate to exacerbation post-eating.

5. A client is scheduled for surgery in the morning and is NPO. Which statement indicates that the client understands the reason for being NPO?

• A. Being NPO helps reduce the risk of nausea.
• B. I should not eat or drink anything to prevent complications during surgery.
• C. NPO reduces the risk of aspiration during surgery.
• D. NPO helps ensure the stomach is empty during surgery.

Correct answer: C

Rationale: The correct answer is C: 'NPO reduces the risk of aspiration during surgery.' When a client is NPO (nothing by mouth) before surgery, it is to prevent aspiration, which can lead to serious complications such as pneumonia. Choice A is incorrect because being NPO is more about preventing aspiration than nausea. Choice B is a general statement without specifying the reason for being NPO. Choice D is partially correct but does not emphasize the crucial aspect of preventing aspiration, which is the primary reason for fasting before surgery.
