1. The doctor ordered Sodium Ampicillin 100 mg I'm. The label on the bottle reads Sodium Ampicillin 1 gran dry powder. Reconstitute by adding 3.4 ml sterile water for injection to yield 1g/4ml (250mg/ml) . How much volume should be administered?
What type of diluent are you adding?
2. Keflin 500 mg IV q6h is ordered. Supply is Keflin 1g . Reconstitute with 4ml diluent to yield 4.4 ml. How much will you give?

Welcome to AN! Show us the math, how you set up the problems and your answers then we can offer help. We won’t do your homework. You need to change your username it sounds like you’re a student, so until you earn the title if nurse, you can’t call yourself one.
Desired/ Available x Quantity = X
1. 100 mg / 1000 mg x 4 ml = 0.4 ml
Type of diluent is sterile water
2. 500 mg / 1000 mg x 4.4 ml = 2.2 ml

Correct, and you also could have done the math using the final concentration given in the problem (250 mg/1 ml). Either is fine.

Correct.
