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. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

3. A client presents to the emergency room with an acute asthma attack. What is the nurse's priority intervention?

• A. Administer bronchodilators as prescribed.
• B. Administer oxygen at 2 liters per nasal cannula.
• C. Perform chest physiotherapy.
• D. Provide emotional support to reduce anxiety.

Correct answer: A

Rationale: The correct answer is to administer bronchodilators as prescribed. During an acute asthma attack, the priority is to open the airways quickly to help the client breathe more easily. Oxygen may be needed but bronchodilators take precedence as they directly target bronchoconstriction. Chest physiotherapy is not indicated in the acute phase of asthma and may exacerbate the condition. While emotional support is important, addressing the airway obstruction takes precedence in this situation.

4. When assessing a client with a diagnosis of bipolar disorder who reports taking a handful of medications, what information is most important to obtain?

• A. What drugs the client used in the suicide attempt.
• B. When the client last took medications for bipolar disorder.
• C. Whether the client has attempted suicide before.
• D. Which family member has the suicide note.

Correct answer: A

Rationale: The correct answer is to obtain information on what drugs the client used in the suicide attempt. This information is crucial for assessing the severity of the overdose, potential drug interactions, and determining the appropriate treatment plan. Choice B is not as urgent as identifying the drugs taken during the suicide attempt. Choice C, while important, is not as immediately critical as knowing the specific medications involved. Choice D is unrelated to the immediate medical needs of the client.

5. When assessing an IV site used for fluid replacement and medication administration, the client complains of tenderness when the arm is touched above the site. Which additional assessment finding warrants immediate intervention by the nurse?

• A. Cool skin at the IV insertion site
• B. Presence of fluid leaking around the IV catheter
• C. Swelling above the IV site
• D. Red streaks tracking the vein

Correct answer: D

Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.
