Correct Answer: B

Rationale: The correct answer is B: 'Changing the patient's position.' Repositioning the patient every 2 hours can be delegated to nursing assistive personnel as it involves physically moving the patient. Tasks like determining the level of comfort (choice A) and assessing circulation (choice D) are clinical judgments that require a nursing license and should be performed by the nurse. Similarly, identifying immobility hazards (choice C) involves critical thinking and assessment skills that are within the nurse's scope of practice.

Correct Answer: A

Rationale: The correct answer is A because ambulating a client is a non-invasive task that can be safely and effectively performed by a nursing assistant. Choice B is incorrect as complex wound care requires specialized skills usually performed by licensed nurses. Choice C involves administering intravenous antibiotics, which also requires a higher level of training and assessment skills than a nursing assistant possesses. Choice D, involving a client who is NPO and requires IV hydration, may involve further assessments and monitoring that are beyond the scope of a nursing assistant.

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 correct answer is B: 'Explain that the DNR must be honored.' The nurse's responsibility is to follow the DNR order, as it is a legal and ethical obligation. Choice A is incorrect because following the family's wishes would go against the established DNR order. Choice C is incorrect as ignoring the DNR order is not appropriate. Choice D is also incorrect as performing CPR would be contrary to the client's expressed wishes in the DNR order.

Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy to maintain a patent airway. After a tracheostomy, the priority intervention is to ensure a clear airway to prevent respiratory distress. Administering pain medication, changing the tracheostomy dressing, and monitoring oxygen saturation are important but are secondary to maintaining a patent airway in a patient who has just undergone a tracheostomy.
