Final answer:
The nursing care delivery model where a RN oversees and coordinates the care provided by a team of nurses and assistive personnel is known as team nursing.
Step-by-step explanation:
The type of nursing care delivery model described in the scenario is team nursing. Team nursing is a model where a registered nurse (RN) coordinates the care provided by a team that includes other RNs, licensed practical nurses (LPNs), and nursing assistive technicians. Within this model, each member of the nursing team contributes their specific skills in caring for a group of patients, but the RN has the ultimate responsibility for coordinating and overseeing the patient care being delivered. This is in contrast to other nursing care models like case management, where nurses coordinate all aspects of a patient's care, primary nursing, where one nurse is responsible for the entirety of a patient's care during their hospital stay, and total patient care, which is similar to primary nursing but typically encompasses a smaller patient caseload for each nurse.
