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. During a thyroid storm, what is the nurse's priority intervention for a client experiencing increased heart rate and tremors?

• A. Administer antithyroid medications as prescribed.
• B. Administer a beta-blocker to control the heart rate.
• C. Monitor the client's temperature closely.
• D. Prepare the client for an emergency thyroidectomy.

Correct answer: A

Rationale: The correct answer is to administer antithyroid medications as prescribed during a thyroid storm. Antithyroid medications help control the overproduction of thyroid hormones, which is crucial in managing symptoms such as increased heart rate and tremors. These symptoms can be life-threatening if not promptly addressed. Administering a beta-blocker (Choice B) may help control the heart rate, but addressing the underlying cause with antithyroid medications is the priority. Monitoring the client's temperature (Choice C) is important but not the priority intervention during a thyroid storm. Lastly, preparing the client for an emergency thyroidectomy (Choice D) is not the initial intervention for managing symptoms of a thyroid storm.

3. A client with deep vein thrombosis (DVT) is prescribed warfarin. What teaching should the nurse provide to the client?

• A. Avoid leafy green vegetables while taking warfarin.
• B. Report any unusual bruising or bleeding.
• C. Take warfarin at the same time every day.
• D. Avoid alcohol consumption while on warfarin.

Correct answer: D

Rationale: The correct answer is D: 'Avoid alcohol consumption while on warfarin.' Alcohol can increase the risk of bleeding when taken with warfarin, so it should be avoided. Choice A is incorrect as leafy green vegetables contain vitamin K, which can interfere with the anticoagulant effects of warfarin. Choice B is important but not directly related to alcohol consumption. Choice C is a general instruction for medication adherence but not specifically related to the interaction with alcohol.

4. An adolescent client with intellectual disability refuses oral hygiene. A behavior modification program is recommended. Which reinforcement is best for the nurse to implement?

• A. Candy for successful oral hygiene tasks.
• B. Tokens for each successful oral hygiene task.
• C. Privilege restrictions for refusing oral hygiene tasks.
• D. Preferred activities or privileges for compliance.

Correct answer: D

Rationale: In this scenario, the best reinforcement for the nurse to implement is preferred activities or privileges for compliance. Positive reinforcement with privileges is effective in encouraging behavior change in adolescents, including those with intellectual disabilities. Choice A (Candy for successful oral hygiene tasks) may not be suitable as it involves providing a sugary reward, which contradicts the goal of oral hygiene. Choice B (Tokens for each successful oral hygiene task) could be effective but may not be as motivating as preferred activities or privileges. Choice C (Privilege restrictions for refusing oral hygiene tasks) focuses on negative reinforcement, which is not as effective as positive reinforcement in behavior modification.

5. The nurse identifies an electrolyte imbalance, a weight gain of 4.4 lbs in 24 hours, and an elevated central venous pressure for a client with full-thickness burns. Which intervention should the nurse implement?

• A. Administer diuretics
• B. Review urine output
• C. Auscultate for irregular heart rate
• D. Increase oral fluid intake

Correct answer: C

Rationale: An elevated CVP and sudden weight gain indicate fluid overload, which can strain the heart. Auscultating for an irregular heart rate is crucial as electrolyte imbalances and fluid shifts after burns can lead to cardiac complications. Monitoring the heart rate is a priority to detect any cardiac distress early. While reviewing urine output and administering diuretics are important interventions, they should come after ensuring the client's cardiac status is stable. Increasing oral fluid intake may exacerbate the fluid overload, making it an inappropriate intervention in this scenario.
