Question- dosage calc


I am not sure if I understand this question, is there extra information in it? Did I solve it correctly?

Administer Azithromycin 500mg IV over 90 minutes. The IVPB solution is mixed as 500mg in 50cc D5W. The IV set being used deliveres 15gtt/ml. The nurse should infuse the antibiotic at how many drops/min?

My answer is:

500mg x 50ml x 15gtt =

90min x 500mg x 1ml



Yes you have set it up correctly but you cannot ever ever have a partial drop so round down to 8gtts/min.


I missed that rounding. I should know better!
