1. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

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 48-year-old client with chronic alcoholism is admitted to the hospital. The nurse would anticipate that the client may be deficient in which vitamins?

Correct answer: A

Rationale: The correct answer is A. Chronic alcoholism commonly leads to deficiencies in B vitamins, particularly thiamine, and vitamin C. Thiamine deficiency can result in serious neurological issues like Wernicke-Korsakoff syndrome, while vitamin C deficiency can lead to scurvy. Choices B, C, and D are incorrect because vitamin D and E deficiencies are not typically associated with chronic alcoholism.

3. A client is receiving a blood transfusion and develops chills and back pain. What is the nurse's first action?

Correct answer: A

Rationale: The correct first action for the nurse is to stop the transfusion and notify the healthcare provider. These symptoms suggest a transfusion reaction, and stopping the transfusion is crucial to prevent further complications. Notifying the healthcare provider ensures timely intervention and appropriate management for the client's condition. Monitoring vital signs, administering diphenhydramine, or preparing to administer an antihistamine can be considered after stopping the transfusion and seeking guidance from the healthcare provider. However, the immediate priority is to halt the transfusion and inform the provider.

4. A client with cirrhosis develops ascites. What is the nurse’s priority intervention?

Correct answer: B

Rationale: The correct answer is B: Restrict fluid intake to manage fluid overload. In a client with cirrhosis developing ascites, the priority intervention is to restrict fluid intake. This helps manage fluid overload, prevent further complications, such as respiratory distress or kidney impairment, and reduce the accumulation of ascitic fluid. Administering diuretics may be a part of the treatment plan, but the primary focus should be on fluid restriction. Positioning the client in Fowler’s position and measuring the abdominal girth are important interventions but not the priority when managing ascites in cirrhosis.

5. Which client is at greatest risk for developing delirium?

Correct answer: B

Rationale: The correct answer is B. Older adults who have attempted suicide are at higher risk for developing delirium, especially in the context of underlying mental health conditions. Choice A is incorrect as sleep disturbances due to pain may lead to discomfort but not necessarily delirium. Choice C is incorrect as taking antipsychotic medications, if managed well, does not inherently increase the risk of delirium. Choice D is incorrect as using supplemental oxygen alone does not significantly increase the risk of developing delirium.
