As always, Z delivers a quality response. You can really pick up a lot working in an IV room, like typical doses, classes of drugs, IV compatibility, good/bad drug colors, why things like daptomycin can't be mixed stat, ad infinitum.
My 2 cents?
-You prob wouldn't be able to get a job in a hospital micro lab unless you were in a program or have preexisting certification as a med technologist.
-You gotta learn how to walk before you learn how to run; hospital internships are set up so you do tech work and know how a hospital runs before you start learning drugs and making clinical interventions. What kind of boss is going to want someone doing clinical stuff if they don't have the rest of the knowledge down pat?
-Even while doing tech work, you definitely learn things ASSUMING that you are motivated, curious, and have willing preceptors. Like when I started seeing azithro 2gm x1 as opposed to typical z pack dosing, or 2gm flagyl x1, or 1 bactrim ss daily*. If you're good at your job, you'd notice the weird things and start asking why and either be like a.) this is wrong or b.) i should find out if this is legit before i call someone out for being wrong. And once you start asking the right questions to the right people, I believe that they will see that you're willing to learn/work.
* actually all of these abx drug examples i picked up in retail, and thankfully had a smart preceptor who was willing to teach me about the clap, trich, and PJP prophylaxis respectively. so you can really learn ID in all sorts of settings.
