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 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.

3. A client with chronic heart failure is admitted with worsening dyspnea. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Assess the client's lung sounds.
• D. Reposition the client to relieve dyspnea.

Correct answer: A

Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.

4. A client with Parkinson's disease is prescribed levodopa/carbidopa. The nurse instructs the client to take the medication with meals. Which rationale should the nurse provide for taking the medication with food?

• A. It enhances the effectiveness of the medication
• B. It helps to improve absorption
• C. It prevents orthostatic hypotension
• D. It reduces gastrointestinal upset

Correct answer: D

Rationale: The correct answer is D: 'It reduces gastrointestinal upset.' Levodopa/carbidopa can cause nausea and other gastrointestinal side effects. Taking the medication with food can help reduce these side effects and improve the client's comfort. Choices A, B, and C are incorrect because taking the medication with food does not primarily enhance effectiveness, improve absorption, or prevent orthostatic hypotension. The main reason for advising to take the medication with meals is to minimize gastrointestinal upset.

5. An older client who had a subtotal parathyroidectomy is preparing for discharge. What finding requires immediate provider notification?

• A. Afebrile with a normal pulse.
• B. No bowel movement since surgery.
• C. No appetite for breakfast.
• D. A positive Chvostek's sign.

Correct answer: D

Rationale: A positive Chvostek's sign indicates hypocalcemia, a complication after parathyroid surgery that requires immediate attention. This sign is manifested by facial muscle twitching when the facial nerve in front of the ear is tapped, indicating neuromuscular irritability due to low calcium levels. Afebrile with a normal pulse (Choice A) is a normal finding and does not require immediate notification. No bowel movement since surgery (Choice B) is common postoperatively due to anesthesia effects and pain medications and usually resolves within a few days; it does not require immediate notification unless accompanied by other concerning symptoms. No appetite for breakfast (Choice C) is a common postoperative finding and does not require immediate notification unless it persists and leads to dehydration or malnutrition.
