The product of biotechnology, filgrastim (NEUPOGEN ), is available in vials containing 0.3 mg of drug in each milliliter. Which choice is equivalent in concentration?

Question

(a) 0.03 mg/0.1 dL

(b) 300 mcg/0.01 dL

(c) 3 mcg/0.01 cL

(d) 300 mcg/10 cL

- Show the solution(s) by using equivalent expressions.

Answer 1

First, I'll convert 0.3 mg / ml to mg/ L and then compare to the various choices provided.

0.3 mg / ml x 1000 ml / L = 300 mg/L

a) 0.03 mg / 0.1 dL x 10 dL/L = 3 mg / L NOT EQUIVALENT

b) 300 ug / 0.01 dL x 10 dL/L x 1 mg/1000 ug = 300 mg/L EQUIVALENT

c) 3 ug / 0.01 cL x 100 cL/L x 1mg/1000 ug = 30 mg/L NOT EQUIVALENT

d) 300 ug / 10 cl x 100 cL/L x 1 mg /1000 ug = 3 mg/L NOT EAUIVALENT
