The physician orders 500 mg of cefepime IV q.12h. The nurse has a
2 g vial of cefepime with the following instructions for
reconstitution:
Single-dose vials for IV/IM administration | Amount of diluent to be added (mL) | Approximate available volume (mL) | Approximate |
1 g (IV) | 10 | 11.3 | 100 |
1 g (IM) | 2.4 | 3.6 | 280 |
2 g (IV) | 10 | 12.5 | 160 |
The nurse is correct to:
Ordered cefepime 500 mg IV q 12.h mean=s every 12 hours
nuRgse has given 2gm of vial of cefepime for reconstitution
Amount of diluent to be added is =10ml, approximate available volume=12.5 ml
Approximate available cefepime concentration =160mg/ml
means 160mg cefepime is in 1 ml
then 1mg will be in =1/160 ml
then 500mg will be available in =(1/160)X 500 ml
=3.1 ml
