Correct Answer: A

Rationale: The correct answer is A: Sterilizing contaminated items. Maintaining medical asepsis involves ensuring that items are free of microorganisms to prevent infections. Sterilizing contaminated items is a crucial step in this process as it eliminates all microorganisms, including spores. Choices B, C, and D do not directly address the process of reducing and preventing the spread of microorganisms. While routinely cleaning the hospital environment is important for cleanliness, it does not guarantee the elimination of all microorganisms. Reapplying a sterile dressing and applying a sterile gown and gloves are specific actions related to personal protective equipment and wound care, not the general maintenance of medical asepsis.

Correct Answer: C

Rationale: The correct answer is C: Teach the patient how to administer insulin. This action is crucial in promoting self-management and control of diabetes. By educating the patient on administering insulin, they can actively participate in their treatment plan. Monitoring blood sugar levels (choice A) is important but doesn't empower the patient to take direct action. Encouraging a diabetic meal plan (choice B) is beneficial but may not directly address the need for insulin administration. Teaching about the complications of diabetes (choice D) is essential but may not be as immediately impactful as teaching insulin administration for day-to-day management.

Correct Answer: A

Rationale: The correct answer is to delegate the task to a licensed practical nurse (LPN). LPNs can typically perform suctioning, but it is essential to consider the state's practice guidelines and hospital policy. Option B, delegating to a registered nurse (RN), is not necessary for this task as LPNs are usually competent to handle suctioning. Option C, delegating to a nursing assistant (NA), may not be appropriate as suctioning may require a higher level of training and expertise. Option D, performing the task independently, is not the best choice as delegation is a key aspect of nursing practice to ensure tasks are appropriately assigned based on competency levels.

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.

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.
