A client is ordered ceftazidime 10 mg/kg for each dose IV. The client weighs 90 kg. The drug is available in vials containing 1 Gram of ceftazidime in 12 mL of sterile water. How many millilitres will the nurse withdraw from the vial? (Use a preceding zero if it applies. Do not use trailing zeros. Round to the nearest tenth)

Calculate the total dose in mg: The client weighs 90 kg and the dose is 10 mg/kg. Total dose = 90 kg x 10 mg/kg = 900 mg Convert the drug available to mg: The vial contains 1 gram of ceftazidime. 1 gram = 1000 mg Determine the concentration of the drug in mg/mL: The vial has 1000 mg of ceftazidime in 12 mL of sterile water. Concentration = 1000 mg / 12 mL = 83.33 mg/mL Calculate the volume to withdraw in mL: Use the concentration as a conversion factor: Volume (mL) = Total dose (mg) / Concentration (mg/mL) Volume (mL) = 900 mg / 83.33 mg/mL = 10.8 mL
