Correct Answer: A

Rationale: The correct answer is to encourage the patient to perform incentive spirometry. Incentive spirometry helps prevent respiratory complications, such as atelectasis, by promoting deep breathing and optimal lung expansion. Ambulating, repositioning, and administering pain medication are important interventions but do not take precedence over preventing respiratory complications in the immediate postoperative period.

Correct Answer: B

Rationale: The correct answer is B: Limit the duration of catheter use. Limiting the duration of catheterization is a crucial method for preventing catheter-associated urinary tract infections (CAUTIs). Prolonged catheter use increases the risk of introducing pathogens into the urinary tract, leading to infections. Using clean gloves for insertion (choice A) is important for preventing contamination but does not address the main cause of CAUTIs. Using a smaller size catheter (choice C) may help reduce trauma but does not directly prevent infections. Changing the catheter tubing every 24 hours (choice D) is not necessary unless clinically indicated, and it is not the most effective method for preventing CAUTIs.

Correct Answer: D

Rationale: The correct answer is D: Notify the provider immediately about the symptoms. Swelling and pallor in a limb can be indicative of serious circulatory issues or compartment syndrome. It is crucial to inform the healthcare provider promptly to assess and address the situation. Administering pain medication (choice A) may temporarily alleviate the symptoms but does not address the underlying cause. Elevating the limb and monitoring closely (choice B) can be beneficial but does not replace the need for immediate professional evaluation. Encouraging movement to reduce swelling (choice C) is contraindicated in this scenario as it may worsen the condition if a circulatory issue or compartment syndrome is present.

Correct Answer: B

Rationale: The correct action for the nurse in this situation is to question the prescription with the provider. Administering a medication dose three times the normal range without clarification could pose serious risks to the client. Consulting with the pharmacist about the dosage or delaying the medication until verification can be made are not the initial steps to take; the nurse should first clarify the prescription with the healthcare provider to ensure patient safety.

Correct Answer: A

Rationale: The correct answer is to administer a bronchodilator as prescribed. This intervention is the priority for a patient with asthma experiencing shortness of breath as it helps relax the airways, making breathing easier. Encouraging the use of an incentive spirometer (Choice B) is beneficial for lung expansion but not the priority in this acute situation. Placing the patient in a high Fowler's position (Choice C) can also help with breathing but is not as immediate as administering a bronchodilator. While monitoring the patient's oxygen saturation closely (Choice D) is important, the immediate action to address the breathing difficulty is administering a bronchodilator.
