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 acute kidney injury has an elevated creatinine level. What is the nurse's priority intervention?

• A. Administer diuretics as prescribed.
• B. Prepare the client for dialysis.
• C. Restrict the client’s fluid intake.
• D. Notify the healthcare provider immediately.

Correct answer: B

Rationale: The correct answer is B: Prepare the client for dialysis. Clients with acute kidney injury and elevated creatinine may require dialysis to support kidney function and remove waste products from the blood. Preparing for dialysis ensures timely intervention in preventing further complications. Administering diuretics (Choice A) may worsen the client's condition by further compromising kidney function. Restricting fluid intake (Choice C) may be necessary in some cases, but it is not the priority over preparing for dialysis. Notifying the healthcare provider (Choice D) is important, but the immediate priority is to prepare for dialysis to address the acute kidney injury and elevated creatinine level.

3. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?

• A. An 8-year-old living in a housing project.
• B. A 2-year-old playing on aging playground equipment.
• C. An adolescent working in a paint factory.
• D. A 10-year-old with Type 1 diabetes.

Correct answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.

4. A client with Type 1 diabetes reports feeling shaky and lightheaded. The nurse checks the client's blood glucose level and it is 60 mg/dL. What action should the nurse take first?

• A. Give the client a glucagon injection
• B. Encourage the client to eat a high-protein snack
• C. Recheck the blood glucose level in 15 minutes
• D. Administer 15 grams of a fast-acting carbohydrate

Correct answer: D

Rationale: The correct answer is D: Administer 15 grams of a fast-acting carbohydrate. The first step in treating hypoglycemia is to quickly raise the client's blood sugar level. Fast-acting carbohydrates like glucose tablets or juice are essential for this purpose. Giving a glucagon injection is typically reserved for severe hypoglycemia when the client is unable to take anything by mouth. Encouraging the client to eat a high-protein snack is not appropriate for immediate treatment of hypoglycemia. Rechecking the blood glucose level in 15 minutes is important after administering the fast-acting carbohydrate to ensure that the blood sugar has returned to a safe level.

5. The nurse is providing education to a client who experiences recurrent levels of moderate anxiety in response to situations and perceived stress. In addition to information about prescribed medication and administration, which instruction should the nurse include in the teaching?

• A. Practice using muscle relaxation techniques
• B. Take medication only when anxiety is at its worst
• C. Avoid interactions that trigger stress
• D. Engage in exercise during anxious periods

Correct answer: A

Rationale: Teaching relaxation techniques, such as muscle relaxation, helps the client manage anxiety more effectively. These techniques can be practiced regularly to reduce overall anxiety and can complement prescribed medications. Choice B is incorrect because medication should be taken as prescribed, not only when anxiety is at its worst. Choice C is incorrect as avoiding interactions that trigger stress may not always be feasible and does not teach the client coping mechanisms. Choice D is incorrect as engaging in exercise during anxious periods may not be the most effective strategy for managing moderate anxiety levels.
