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 hypertension has been prescribed a calcium channel blocker. What should the nurse include in the client's teaching plan?

• A. Monitor heart rate regularly
• B. Avoid potassium-rich foods
• C. Increase fluid intake to avoid dehydration
• D. Take the medication with food

Correct answer: A

Rationale: Corrected Rationale: Calcium channel blockers can cause bradycardia, so it is important for the client to monitor their heart rate regularly. This helps detect any significant changes in heart rate that may require medical attention. Choice B is incorrect because there is no need to avoid potassium-rich foods with calcium channel blockers. Choice C is incorrect as increasing fluid intake is not specifically related to calcium channel blockers. Choice D is incorrect as calcium channel blockers are usually taken with or without food, depending on the specific medication, but not specifically on an empty stomach.

3. A client with chronic obstructive pulmonary disease (COPD) is experiencing difficulty breathing. What is the nurse's priority intervention?

• A. Administer a bronchodilator via nebulizer.
• B. Increase the client's oxygen flow rate.
• C. Elevate the head of the bed.
• D. Reposition the client to a side-lying position.

Correct answer: B

Rationale: In clients with COPD experiencing difficulty breathing, increasing the client's oxygen flow rate is the priority intervention. This action helps to improve oxygenation and relieve shortness of breath. While bronchodilators and other medications may be necessary, providing immediate oxygen support is crucial. Elevating the head of the bed and repositioning the client can assist with breathing comfort but do not address the immediate need for improved oxygenation in COPD exacerbation.

4. A client is admitted with a diagnosis of schizophrenia. The client refuses to take medication and states 'I don't think I need those medications. They make me too sleepy and drowsy. I insist that you explain their use and side effects.' The nurse should understand that

• A. A referral is needed to the psychiatrist who is to provide the client with answers
• B. The client has a right to know about the prescribed medications
• C. Such education is an independent decision of the individual nurse whether or not to teach clients about their medications
• D. Clients with schizophrenia are at a higher risk of psychosocial complications when they know about their medication side effects

Correct answer: B

Rationale: The correct answer is B. The client has a legal right to be informed about their treatment, including medication uses and side effects, as part of informed consent. This helps ensure that the client can make an informed decision about their care. Choice A is incorrect because the nurse can provide the client with information about their medications. Choice C is incorrect as it is not an independent decision of the nurse but a professional responsibility to educate clients. Choice D is incorrect as knowledge about medication side effects can actually empower clients to manage their condition effectively.

5. A 4-year-old child falls off a tricycle and is admitted for observation. How can the nurse best facilitate the child's cooperation during the assessment?

• A. Ask the parent to hold the child during the assessment.
• B. Allow the child to play with a syringe without a needle.
• C. Ask the child to blow out the penlight as if to simulate success.
• D. Explain the function of each organ during the assessment.

Correct answer: C

Rationale: Engaging the child in blowing out the penlight simulates play and can reduce fear, helping with cooperation during the assessment. Choice A is not recommended as it may increase anxiety by separating the child from the parent. Choice B is not appropriate as it involves playing with a syringe, which may not be safe or suitable. Choice D is not ideal for a 4-year-old child as understanding organ functions may be beyond their developmental level.
