Final answer:
The element of duty can be proven in this scenario.
Step-by-step explanation:
In this scenario, the element of duty can be proven. The pharmacy manager had a duty to monitor the IV admixture room by notifying the attending pharmacist. By notifying the pharmacist, the manager assumed responsibility for overseeing and ensuring the proper operations and safety of the room. If any negligence occurred in the IV admixture room, the pharmacy manager can be held liable for breaching their duty.
