Calculation
The label on a 2 gram vial of cefotaxime sodium powder for reconstitution reads, "Reconstitute with 50 mL of normal saline." After reconstitution with the 50 mL of normal saline, how many mg will each mL contain? (Enter numeric value only.)
mg/mL
Explanation & Rationale
Given: Vial strength: Cefotaxime 2 grams (2000 mg) Volume of diluent: 50 mL of normal saline Step 1: Calculate the concentration of Cefotaxime in the reconstituted solution: Concentration (mg/mL) = Total amount of Cefotaxime (mg) / Total volume of solution (mL) Concentration (mg/mL) = 2000 mg / 50 mL Concentration (mg/mL) = 40 mg/mL
