Okay, Dumb question=Diluting meds

Published

The threads about diluting phenergren and nexium reminded me. I want some tips.

For instance, if you give 12.5 of phenergren, the vial is 1 ml = 25 so you have to pull 1/2 a ml. We use syringes with the sharp tip plastic "needles". If I pull 1.2 cc to be accurate I would have to use either a TB 1 ml or a 3 cc syringe to get the right amt. of phenergren. Then I need to add 10 cc of saline. I cant transfer the drug to a larger syringe without loosing some. I cant start with a 10 cc saline filled syringe and squirt out 1/2 cc of saline accurately and fill it accurately with the phenergren. I cant accurately pul 1/2 cc in a 10 cc empty syringe and fill it with saline. What do you do??

If the whole amt (25CC or whatever) of the vial is to be used then of course there is no problem, I load the vial in an empty syringe and then draw up the saline to dilute it.

So far I have had to draw out 1/2 cc in a small syringe and waste it thus having the correct amt. left in the bottle to draw into a larger syringe. Is this the only way??? Help.

Same if I get an order for toradol 15 and all we have is 30 ml vials, etc. I cant imagine if the order is going to be 6.25 of that 25 cc vial.

Maybe this is a dumb ques too, but I thought this was a good place to ask. During my preceptorship (for school) in the Trauma ICU, my preceptor first of all told me "if the pts alive push e/t slow, and if they're dying push fast", well I obviously know that there's more of a science to pushing meds than this - but my question is, I'm getting ready to go to the ED c a new Preceptor, and I'm wondering what's the best pckt ref. I can get to for IV meds - to find out how fast I should be pushing, compatibilities, etc.

Also,

When I administered Phenytoin, Dilaudid etc via an infusing port he never told me to Dilute them, only to Pre/Post flush.... is this correct? He also confused me even more bc he also said many other times, that if I'm running NS I don't need to flush - so what is the Criteria for when to flush, when to dilute etc while infusing NS?

Even when 3/5/10ml NS would appear as a maintenance, he would tell me to just scan them in, that we didn't need to admin them if there was NS running.... I get the reason behind maintenance flushes, but I can also see his point that the NS already running - I just wonder why they would appear as sched if I don't hv to admin them? Maybe he's right, but I noticed him doing some pretty lazy/shady things as time went on, and I don't want to go into the next rotation with these bad habits!

I just don't understand how on such a busy floor as this was, a new RN could ever have the time to look-up everything. Many times when I would ask spec. quests about drugs - flushing - etc. the RNs were clueless, they just knew the way that had "always done it", but had no real reason behind it...

Thanks for your help! I've learned so much from you guys! :bow:

Sorry for the Novel!
