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 asthma is prescribed an inhaled corticosteroid. What teaching should the nurse provide?

• A. Rinse the mouth with water after using the inhaler.
• B. Take the medication only during asthma attacks.
• C. Avoid using the inhaler before exercise.
• D. Clean the inhaler with hot water after each use.

Correct answer: A

Rationale: The correct teaching the nurse should provide to a client prescribed an inhaled corticosteroid is to rinse the mouth with water after using the inhaler. This helps prevent oral fungal infections, a common side effect of inhaled corticosteroids. Choice B is incorrect because inhaled corticosteroids are usually used regularly, not just during asthma attacks. Choice C is incorrect as using the inhaler before exercise can actually help prevent exercise-induced bronchospasm. Choice D is incorrect because cleaning the inhaler with hot water after each use is not necessary and may damage the device.

3. A combination multi-drug cocktail is being considered for an asymptomatic HIV-infected client with a CD4 cell count of 500. Which nursing assessment of the client is most crucial in determining whether therapy should be initiated?

• A. Presence of viral symptoms
• B. Engages in high-risk behaviors
• C. Willingness to comply with complex drug schedules
• D. History of opportunistic infections

Correct answer: C

Rationale: The most crucial nursing assessment in determining whether therapy should be initiated for an asymptomatic HIV-infected client with a CD4 cell count of 500 is the client's willingness to comply with complex drug schedules. Adherence to antiretroviral therapy is essential for its effectiveness. Assessing the client's willingness and ability to comply with the complex medication regimen is crucial to ensure successful treatment and prevent drug resistance. Choices A, B, and D, although important in the overall care of the client, are not as crucial as assessing the client's willingness to adhere to the prescribed drug regimen.

4. A client with a urinary tract infection is prescribed ciprofloxacin. What is the most important teaching the nurse should provide?

• A. Take the medication with milk to prevent stomach upset.
• B. Increase fluid intake to 2-3 liters per day.
• C. Avoid taking the medication with dairy products.
• D. Continue taking the medication even if symptoms improve.

Correct answer: B

Rationale: Ciprofloxacin can cause crystalluria, so increasing fluid intake to 2-3 liters per day helps flush out the medication and prevent crystal formation in the kidneys. This also ensures adequate hydration, which supports the body's ability to fight the infection. Choice A is incorrect because ciprofloxacin should not be taken with dairy products as they can interfere with the absorption of the medication. Choice D is incorrect because although it's important to complete the full course of antibiotics, it's equally crucial to report any improvement in symptoms to the healthcare provider.

5. 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.
