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. After an older client receives treatment for drug toxicity, the healthcare provider prescribes a 24-hour creatinine clearance test. Before starting the urine collection, the nurse noted that the client's serum creatinine was 0.3 mg/dL. Which action should the nurse implement?

• A. Check the client's urine output hourly
• B. Instruct the client to increase fluid intake
• C. Notify the healthcare provider of the results
• D. Start the 24-hour urine collection

Correct answer: C

Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.

3. An antibiotic IM injection for a 2-year-old child is ordered. The total volume of the injection equals 2.0 ml. The correct action is to

• A. Administer the medication in 2 separate injections
• B. Give the medication in the dorsal gluteal site
• C. Call to get a smaller volume ordered
• D. Check with the pharmacy for a liquid form of the medication

Correct answer: A

Rationale: Injections over 1 mL should be split into two separate injections for young children. This helps in preventing discomfort, ensuring proper absorption, and reducing the risk of tissue damage. Giving the medication in one injection of 2.0 ml might be too much for a 2-year-old child. Choices B and D are incorrect because the dorsal gluteal site is not recommended for children due to potential injury, and changing the form of medication might not be necessary if the volume can be adjusted. Choice C is unnecessary as splitting the dose into two injections is the appropriate action.

4. A client with a history of hypertension and hyperlipidemia is admitted with chest pain. What is the nurse's priority action?

• A. Administer prescribed nitroglycerin.
• B. Obtain a 12-lead electrocardiogram (ECG).
• C. Check the client's vital signs.
• D. Place the client on continuous telemetry.

Correct answer: B

Rationale: The correct answer is to obtain a 12-lead electrocardiogram (ECG). This action is crucial in assessing the heart's electrical activity and helps in the evaluation of chest pain. Administering nitroglycerin (Choice A) may be necessary but should come after obtaining the ECG to confirm the diagnosis. Checking vital signs (Choice C) is important but does not provide direct information about the heart's electrical status. Placing the client on continuous telemetry (Choice D) may be appropriate later but does not provide immediate information on the heart's electrical activity as an ECG does.

5. A client with Alzheimer’s disease is becoming increasingly confused. What action should the nurse take first?

• A. Reorient the client to time and place.
• B. Monitor the client’s vital signs.
• C. Provide the client with calming activities to reduce confusion.
• D. Consult with the healthcare provider about adjusting the client’s medication.

Correct answer: B

Rationale: The correct action for the nurse to take first when a client with Alzheimer’s disease is becoming increasingly confused is to monitor the client’s vital signs (Choice B). Increased confusion in Alzheimer’s disease patients may indicate underlying issues like infection, dehydration, or medication side effects. Monitoring vital signs is crucial in identifying any potential causes of the confusion. Choices A, C, and D are not the priority in this situation. Reorienting the client to time and place (Choice A) can be helpful but is not the first priority. Providing calming activities (Choice C) and consulting with the healthcare provider about medication adjustments (Choice D) may be necessary but should come after assessing the client's vital signs to rule out immediate physical causes of confusion.
