Is it the nurse or nurse assiStant respoNsibilty to reposition a patient?

Nursing Assistants are extremely important members of the health care team. They assume many responsibilities for the registered nurse(RN) or the licensed practical nurse (LPN) which otherwise may not be able to be accomplished in the time limits that governing boards set as "Standards of Care". For instance, a patient who is bed bound needs to be "repositioned" or turned a minimum of every 2 hours. Imagine if a single person were responsible for doing this to 8, 10, or 12 patients in addition to medicating, treating, toileting, cleaning, and comforting these patients! This activity is one of the activities that state governing boards have allowed to be "delegated" to assistive personnel, such as a nurses assistant. While it may be understood that turning a patient is the responsibility of the nurse assistant, it is the responsibility that the registered nurse "delegate" the task and "supervise" that the task is completed.
