A nurse is planning care for clients. Which of the following tasks can the nurse delegate to an assistive personnel (AP)?

A. Assessment of a postoperative client requires advanced clinical judgment to identify potential complications like hemorrhage or anesthesia reactions. This task is strictly within the scope of practice of the registered nurse and cannot be delegated to unlicensed personnel. The nurse must personally evaluate the patient's stability and physiological response following a major surgical procedure. B. Obtaining vital signs, such as blood pressure, on a stable client is a routine task that falls within the job description of assistive personnel. Since the client is stable and preparing for discharge, this task does not require complex clinical interpretation by the nurse at the moment of collection. The nurse remains responsible for reviewing the results and ensuring they are within expected limits. C. Tracheostomy care is an invasive procedure that involves the airway and requires specialized knowledge of sterile technique and respiratory assessment. Due to the high risk of complications such as airway obstruction or infection, this task must be performed by a licensed nurse. Assistive personnel are not trained to manage artificial airways or assess the integrity of the stoma. D. Patient teaching is a core nursing responsibility that involves evaluating the patient's readiness to learn and their understanding of the material. While an AP can encourage a patient to use the device, the initial instruction and demonstration must be performed by the registered nurse. Effective teaching requires the clinical expertise to explain the rationale and correct the patient's technique.
