I'm studying my meds for NCLEX prep and just for my own knowledge and I came across Lasix. I know that Lasix IVpush is to be given slow or your going to cause ototoxicity, bla bla bla. I know that. I want to know an exact number that it is to be pushed like how many mg/min? I read somewhere in a drug book that you need to give the smallest vial of Lasix (20mg/2mL) at least over 2 minutes. Now, as I'm reading over this Lasix flashcard it says to give Lasix no more than 4mg/min. I googled it and now I'm finding that you don't give IV Lasix AT ALL when your dose is over 20mg? I've been instructed to give 80mg of Lasix IV push. I gave that at about 5 minutes. I'm hoping this is all making sense. Can someone please clear up the confusion. How fast am I supposed to push IV Lasix undiluted? Please don't just say "slow".
