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 clinical judgment and is a task that must be performed by a licensed nurse. B. Client teaching requires nursing knowledge and is within the scope of practice for licensed nurses, not assistive personnel. C. Obtaining vital signs, such as blood pressure, is within the scope of practice for assistive personnel and can be safely delegated in stable clients. D. Tracheostomy care is a sterile procedure and requires nursing knowledge and skills, making it inappropriate to delegate to an AP.
