Final answer:
The nursing care delivery model where a registered nurse oversees patient care from admission to discharge, with assistance from associate nurses, is known as primary care nursing.
Step-by-step explanation:
The nursing care delivery model being described in the question is primary care nursing. In this model, a registered nurse is assigned to a group of patients and is responsible for coordinating and providing comprehensive care from admission to discharge. Although the primary nurse may have associate nurses assisting with care, the primary nurse maintains the role of the central caregiver, emphasizing continuity of care within the hospital setting. This model enables the nurse to develop a therapeutic relationship with the patients and their families, providing personalized care and attending to physical, emotional, and educational needs.
