I have not started nursing school yet, but I do have question.. My grandma just got Gentimycin tonight and the pharmacy around here is not open...... The medication is 80 mg/2 ml She needs to take 60 mg IM..... Can you help me calculate this into ML so I can give her her injections... I tried and I came up with 1.5 ML.......but I dont want to give her any until I get the right answer..... THanks
