    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

    Step 1: Identify the dosage. 750 mg Step 2: Identify the volume for reconstitution. 100 mL Step 3: Calculate the concentration. 750 ÷ 100 = 7.5 mg/mL
