I'm a PGY-2 pathology resident. I didn't know antibiotic regimens that well as a med student and I know less now. Is there a good shorthand or resource to brush up with? I've been going through the Uworld CCS cases and have had a few where I didn't know what antibiotic to use so I just went straight to the big guns like imipenem. The patient wouldn't improve even though cultures eventually came back as sensitive. Obviously, the software is looking for something more specific, but I'm terrible with this crap.
