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. What safety measure should the nurse take for a client with a seizure disorder who has an IV line?

• A. Ensure that the IV site is padded and protected.
• B. Limit the client's mobility to prevent dislodging the IV.
• C. Place the IV site on the same side as the seizure activity.
• D. Ensure the client is positioned on the opposite side of the IV line.

Correct answer: D

Rationale: The correct answer is D: Ensure the client is positioned on the opposite side of the IV line. Placing the IV line on the opposite side of any seizure activity is essential to prevent injury. It helps to ensure that the IV line is not dislodged during a seizure. Choices A, B, and C are incorrect. While padding and protecting the IV site is important, the priority is to position the client on the side opposite to the IV line to prevent dislodgement and injury during a seizure.

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

• A. Avoid foods high in vitamin K, such as spinach.
• B. Report any signs of bleeding, such as bruising or nosebleeds.
• C. Take the medication on an empty stomach.
• D. Monitor for changes in blood pressure.

Correct answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.

4. A client with a recent myocardial infarction is prescribed a beta-blocker. What side effect should the nurse monitor for?

• A. Monitor the client for bradycardia.
• B. Check the client’s blood pressure for signs of hypotension.
• C. Monitor the client for signs of hyperglycemia.
• D. Monitor for signs of fluid retention.

Correct answer: B

Rationale: The correct answer is B: 'Check the client’s blood pressure for signs of hypotension.' Beta-blockers can lead to decreased heart rate, but bradycardia is not the primary side effect to monitor. Monitoring for bradycardia is more relevant when administering medications like digoxin. Hyperglycemia is associated with medications like corticosteroids, not beta-blockers. Fluid retention is a side effect seen with medications like corticosteroids or calcium channel blockers, not beta-blockers. Therefore, in a client taking a beta-blocker after a myocardial infarction, monitoring for hypotension is crucial due to the medication's mechanism of action.

5. A client is prescribed metformin for type 2 diabetes. What should the nurse emphasize in the client's teaching?

• A. Take the medication with meals to reduce the risk of GI upset.
• B. Report any muscle pain to the healthcare provider promptly.
• C. Avoid alcohol consumption while taking this medication.
• D. Monitor blood sugar levels regularly to prevent hypoglycemia.

Correct answer: C

Rationale: The correct answer is to avoid alcohol consumption while taking metformin. Alcohol can increase the risk of lactic acidosis when combined with metformin. Choice A is incorrect because metformin is usually recommended to be taken with meals to reduce GI upset. Choice B is important but not the priority; muscle pain is more commonly associated with other diabetes medications. Choice D is incorrect because metformin typically does not cause hypoglycemia but rather helps control blood sugar levels in type 2 diabetes.
