Final answer:
If a required drug is not available from floor supplies or night cabinets in a hospital emergency room, protocols are in place to ensure it is obtained promptly, such as contacting the pharmacy department or the hospital's central supply department.
Step-by-step explanation:
In a hospital emergency room, a physician may order an intravenous (IV) delivery of a specific medication. However, if the medication is not available from the floor supplies or night cabinets, there are protocols in place to ensure that the required drug is obtained promptly.
One common protocol is to contact the pharmacy department to request the medication. The pharmacy department can then prepare the medication and deliver it to the emergency room.
Another option is to contact the hospital's central supply department, which may have a stock of emergency medications that can be quickly accessed.
