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 lactulose for signs of hepatic encephalopathy. To evaluate the therapeutic response, which assessment should the nurse obtain?

• A. Percussion of the abdomen.
• B. Blood glucose level.
• C. Serum electrolytes.
• D. Level of consciousness.

Correct answer: D

Rationale: The correct answer is D: Level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy, which can affect brain function. Therefore, monitoring the client's level of consciousness is crucial to evaluate the therapeutic response. Changes in consciousness can indicate the effectiveness of lactulose in reducing ammonia levels. Choices A, B, and C are incorrect because while they are important assessments in various conditions, they are not specifically related to evaluating the therapeutic response of lactulose in hepatic encephalopathy.

3. A client with acute pancreatitis is receiving nothing by mouth (NPO) status. What is the nurse's priority intervention?

• A. Administer antiemetic medication as prescribed.
• B. Monitor the client's intake and output.
• C. Provide mouth care to keep the client comfortable.
• D. Elevate the client's head of the bed.

Correct answer: B

Rationale: The correct answer is B: Monitor the client's intake and output. When a client with acute pancreatitis is on NPO status, the nurse's priority intervention is to monitor the client's intake and output. This is crucial to assess for signs of dehydration, electrolyte imbalances, and to ensure the client is responding appropriately to treatment. Administering antiemetic medication (choice A) may be necessary for managing nausea and vomiting but is not the priority over monitoring intake and output. Providing mouth care (choice C) and elevating the client's head of the bed (choice D) are important aspects of care but do not take precedence over monitoring intake and output to prevent complications in clients with NPO status due to acute pancreatitis.

4. Which foods should a healthcare provider recommend for a child with phenylketonuria (PKU) to avoid?

• A. Fresh fruit and vegetables
• B. Foods sweetened with aspartame
• C. Bread with honey
• D. Gluten-rich bread

Correct answer: B

Rationale: The correct answer is B: 'Foods sweetened with aspartame.' Children with PKU must avoid foods containing aspartame because it breaks down into phenylalanine, which can worsen their condition. Choice A, fresh fruit and vegetables, are generally healthy and safe for individuals with PKU. Choice C, bread with honey, is also safe unless the bread contains artificial sweeteners like aspartame. Choice D, gluten-rich bread, is not specifically problematic for individuals with PKU unless it contains aspartame or other substances high in phenylalanine.

5. A 17-year-old adolescent reports flu-like symptoms and is brought to the emergency room. What intervention should the nurse implement first?

• A. Assess the client's temperature.
• B. Place a mask on the client.
• C. Obtain a chest X-ray per protocol.
• D. Determine the client's blood pressure.

Correct answer: B

Rationale: The correct answer is to place a mask on the client. This intervention is crucial in preventing the spread of infections like the flu, especially in a healthcare setting where the risk of transmission is high. Assessing the client's temperature (Choice A) can be important but is not the priority in this situation. Obtaining a chest X-ray (Choice C) and determining the client's blood pressure (Choice D) are not the immediate interventions needed for a 17-year-old reporting flu-like symptoms.
