Final answer:
The nursing care delivery model being used is Total patient care, where the nurse provides comprehensive care for both patients.
Step-by-step explanation:
The nursing care delivery model being used in this scenario is Total patient care. In this model, the nurse takes on the responsibility of providing comprehensive care for both of her patients throughout her entire shift.
With total patient care, the nurse is directly responsible for all aspects of the patient's care, including assessments, medication administration, treatments, and coordination of care.
Some examples of total patient care include a nurse caring for a post-operative patient in the ICU or a nurse providing care for an elderly patient in a long-term care facility.
