Final answer:
False. In early civilizations influenced by animism, the roles of physician and nurse were not interchangeable.
Step-by-step explanation:
The statement, 'In early civilizations influenced by the theory of animism, the roles of physician and nurse were interchangeable' is False.
In early civilizations influenced by the theory of animism, such as ancient Mesopotamia, medicine and magic were closely intertwined. The priests in these civilizations practiced divination and used both religious and magical practices to try to understand and influence the universe.
However, the roles of physician and nurse were not interchangeable. Physicians were typically the ones responsible for diagnosing and treating illnesses, while nurses assisted with patient care and provided support. These roles were distinct and had different levels of expertise and responsibility.
