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. An older adult client is admitted with pneumonia and prescribed penicillin G potassium. Which factor increases the risk of an adverse reaction?

• A. Sputum culture showing Streptococcus pneumoniae.
• B. Previous treatment with penicillin.
• C. Daily use of spironolactone for hypertension.
• D. Documented allergy to sulfa drugs.

Correct answer: C

Rationale: The correct answer is C. Daily use of spironolactone for hypertension can increase the risk of hyperkalemia and interact with penicillin, leading to adverse reactions. Choice A is incorrect because the sputum culture showing Streptococcus pneumoniae is an expected finding in a patient with pneumonia and does not increase the risk of an adverse reaction to penicillin. Choice B is incorrect as previous treatment with penicillin does not necessarily increase the risk of an adverse reaction to penicillin if there was no history of allergic reactions. Choice D is also incorrect as a documented allergy to sulfa drugs does not directly increase the risk of an adverse reaction to penicillin.

3. The nurse is feeding an older adult who was admitted with aspiration pneumonia. The client is weak and begins coughing while attempting to drink through a straw. Which intervention should the nurse implement?

• A. Encourage the client to drink more slowly
• B. Stop feeding and assess for signs of aspiration
• C. Elevate the head of the bed further
• D. Teach coughing and deep breathing exercises

Correct answer: B

Rationale: When an older adult with aspiration pneumonia coughs while attempting to drink, it may indicate aspiration. Aspiration can lead to serious complications. Therefore, the appropriate intervention for the nurse in this situation is to stop feeding immediately and assess the client for signs of aspiration. Encouraging the client to drink more slowly (Choice A) may not address the risk of aspiration. Elevating the head of the bed further (Choice C) is generally beneficial to prevent aspiration but is not the priority when immediate assessment is needed. Teaching coughing and deep breathing exercises (Choice D) is not appropriate when the client is actively coughing during feeding and requires immediate assessment for potential aspiration.

4. The nurse is preparing a teaching plan for a client diagnosed with asthma. The primary purpose of the plan is to

• A. Prevent respiratory infections
• B. Prevent airway inflammation
• C. Maintain an open airway
• D. Avoid allergens that trigger attacks

Correct answer: D

Rationale: Avoiding allergens that trigger asthma attacks is crucial in managing the condition and preventing exacerbations. While preventing respiratory infections and maintaining an open airway are important aspects of asthma management, the primary focus of the teaching plan is to help the client identify and avoid allergens that could trigger asthma attacks. This proactive approach can significantly reduce the frequency and severity of asthma symptoms.

5. 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?

• A. Vitamin B and vitamin C
• B. Vitamin D and vitamin E
• C. Vitamin K and vitamin A
• D. Vitamin A and vitamin E

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.
