A nurse is working with an assistive personnel (AP) in a health clinic during an outbreak of influenza. Which of the following tasks should the nurse delegate to the AP?

The correct answer is D: Perform a simple dressing change for a client. This task can be safely delegated to an assistive personnel (AP) as it does not require specialized nursing knowledge or assessment skills. The AP can follow a standardized procedure under the supervision of the nurse. Choices A, B, and C involve tasks that require nursing judgment, critical thinking, and specialized skills, and should not be delegated to an AP. Providing advice over the telephone (Choice A) involves assessing the client's condition and determining the appropriate course of action. Inserting an NG tube (Choice B) and teaching a client to walk on crutches (Choice C) require specific training and expertise to ensure client safety and well-being. Therefore, these tasks are not appropriate for delegation to an AP.
