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 a history of hypertension and hyperlipidemia is admitted with chest pain. What is the nurse's priority action?

• A. Administer prescribed nitroglycerin.
• B. Obtain a 12-lead electrocardiogram (ECG).
• C. Check the client's vital signs.
• D. Place the client on continuous telemetry.

Correct answer: B

Rationale: The correct answer is to obtain a 12-lead electrocardiogram (ECG). This action is crucial in assessing the heart's electrical activity and helps in the evaluation of chest pain. Administering nitroglycerin (Choice A) may be necessary but should come after obtaining the ECG to confirm the diagnosis. Checking vital signs (Choice C) is important but does not provide direct information about the heart's electrical status. Placing the client on continuous telemetry (Choice D) may be appropriate later but does not provide immediate information on the heart's electrical activity as an ECG does.

3. A nurse is caring for a 73-year-old male client with Alzheimer's disease. Which action should the nurse take to enhance the client's nutritional intake?

• A. Encourage the client to eat large meals in one sitting.
• B. Offer the client frequent snacks of foods he enjoys.
• C. Provide the client with foods high in fiber to improve digestion.
• D. Discourage eating late at night to prevent weight gain.

Correct answer: B

Rationale: Offering frequent snacks of foods the client enjoys is the most appropriate action to enhance the nutritional intake of a client with Alzheimer's disease. This approach helps to ensure that the client receives an adequate amount of nutrients throughout the day, especially when larger meals might be challenging for individuals with Alzheimer's. Encouraging large meals in one sitting (Choice A) may overwhelm the client and lead to decreased food intake. While foods high in fiber (Choice C) are beneficial for digestion, the primary focus should be on providing foods the client enjoys to increase intake. Discouraging eating late at night (Choice D) is not directly related to enhancing nutritional intake in this scenario.

4. A client with a tracheostomy develops copious, thick secretions. What is the nurse's priority action?

• A. Increase the client's fluid intake.
• B. Perform tracheal suctioning.
• C. Administer a mucolytic agent.
• D. Increase the humidity of the oxygen source.

Correct answer: D

Rationale: The correct answer is to increase the humidity of the oxygen source. This action helps thin thick secretions, making them easier to clear from the tracheostomy tube. Increasing fluid intake (Choice A) can be beneficial in some cases but addressing humidity is more specific to managing thick secretions in a client with a tracheostomy. Tracheal suctioning (Choice B) should be done after attempting to thin the secretions with increased humidity. Administering a mucolytic agent (Choice C) is a possible intervention but typically comes after addressing humidity and before resorting to suctioning to avoid unnecessary invasiveness.

5. 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.
