    Calculation

    Ceftazidime 750 mg IV every 12 hours is prescribed for a client with an infection. The directions on the label of the 750 mg vial instruct the nurse to reconstitute with 100 mL sterile water. The reconstituted medication provides how many mg/mL? (Enter numeric value only If rounding is required, round to the nearest tenth.)

    mg/mL

    Explanation & Rationale

    Here's how to calculate the concentration (mg/mL) of the reconstituted ceftazidime solution: We know: Total ceftazidime content after reconstitution: 750 mg (given) Reconstitution volume: 100 mL sterile water (given) We need to find: Concentration of ceftazidime in mg/mL after reconstitution Calculation: Concentration (mg/mL) = Total amount of medication (mg) / Volume after reconstitution (mL) Concentration (mg/mL) = 750 mg / 100 mL Concentration (mg/mL) = 7.5 mg/mL (round to nearest tenth) Therefore, the reconstituted ceftazidime medication provides 7.5 mg/mL.
