Which intervention is most effective in preventing postoperative complications?

Correct Answer: B

Rationale: The most effective intervention in preventing postoperative complications is to ambulate the patient as soon as possible. Early ambulation helps prevent complications like deep vein thrombosis and pneumonia by enhancing circulation and preventing respiratory issues. Encouraging the patient to drink fluids, perform deep breathing exercises, or range of motion exercises are beneficial interventions, but ambulation is the priority due to its overall impact on preventing various postoperative complications.

Correct Answer: B

Rationale: The priority action when a patient has a fever is to assess the patient's temperature regularly. Monitoring the temperature helps track the effectiveness of interventions and detect any worsening fever. Administering antipyretic medication (Choice A) should be done based on healthcare provider's orders after assessing the patient's condition. While providing cooling measures such as a cool compress (Choice C) can help reduce fever, assessing the temperature takes precedence. Providing blankets for comfort (Choice D) is not the priority when dealing with a fever.

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: A

Rationale: The correct answer is to encourage early ambulation and leg exercises. By promoting early ambulation and leg exercises, blood flow is enhanced, reducing the risk of venous thromboembolism (VTE) in postoperative patients. Choice B, applying compression stockings, helps prevent VTE but is not as effective as early ambulation and exercises. Choice C, administering anticoagulants, is important in VTE prevention but does not directly address improving circulation through physical activity. Choice D, elevating the patient's legs, may be beneficial for circulation in specific cases but is not as effective in preventing VTE as early ambulation and leg exercises.
