Calling it a drip isn't wrong.

The type of pump used to the control the drip is simply called a PCA (at least in this hospital -- patient controlled analgesia).
A student no longer! And only a lowly nurse.
Feel free, but forgive me if I don't have an answer for you.
If it makes you feel any better, I only have a job now as a sales associate in a ladies shoe department at the mall.
I need monies to pay for my exam and my license. And loans.
So you'll still be making much, much more money than I will.
