What term describes the process of infusing multiple medications through separate bags but the same IV line?

The term that describes the process of infusing multiple medications through separate bags but the same IV line is "Concurrent administration." This terminology indicates that different medications are being delivered at the same time through a single intravenous access point.

Concurrent administration is particularly relevant in clinical settings where multiple treatments or medications are necessary for a patient, and it requires careful management to ensure that the medications do not interact adversely while still being administered concurrently.

The other terms may relate to similar processes but have distinct meanings or implications. For instance, "Simultaneous infusion" and "Co-infusion" suggest the administration of medications at the same time but can imply more direct mixing, which is not the case when using separate bags. "Parallel administration" generally refers to the administration of two or more treatments independently, but not necessarily through the same IV line.

Therefore, the correct answer captures the specifics of using one IV line for simultaneous delivery of medications stored in separate containers.
