I am a newly graduated nursing student and my friends and I have encountered differences in how to deal with volume differences in IV medication drawn from ampoules. One heparin ampoule had 0.3ml instead of 0.2ml when drawn up (5000IU in 0.2ml was written on the ampoule).
1) One nurse said discard the whole medication; you dont know how much is the correct dose.
2) second nurse said discard the difference and you will be fine
3) third nurse said discrepancies could be due to the syringe; allow for +/-10% difference.
4) fourth nurse said give the whole amount: Extra volume could be due to "condensation" in the factory???????????
What r your thoughts? What would you do?
