Here's the question: It was a pediatric dose of an antibiotic, came in a concentration of 100mg/1mL, pt. needed 500mg so it came in a syringe of 5mL..... therefore 500mg/5mL I looked up on Lexicomp peds administration and to be given IV it had to e diluted to a concentration of 20mg/1mL. How much NS would you add to the syringe? And how did you get this? I was in clinical and my instructor did it differently and I do not understand how she got that answer because I got a different one. I'm curious to see what others do without me telling what I did first.
