Final answer:
The nursing care model used by a registered nurse leading practical nurses and nursing assistive personnel is Team Nursing. It involves direct supervision, coordination, and delegation of tasks within a team to ensure efficient patient care.
Step-by-step explanation:
When a registered nurse is leading a group of practical nurses and nursing assistive personnel, the nursing care model being used is Team Nursing. This model involves collaboration and shared responsibilities within a team led by an RN who is responsible for coordinating care. In this setting, the RN provides direct supervision to the team, ensuring that patient care is efficient and effective. Within the team nursing model, each member might have specific tasks; for example, some may focus on providing dialysis treatments, which includes activities such as reviewing patient history, assessing patient needs, monitoring the treatment process, recording vital signs, and preparing sterile equipment. This approach enables a division of labor that can ensure that all aspects of patient care are addressed within a structured environment like the ICU, CGU, emergency, or medical-surgical units.
