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 milliliters will the nurse withdraw from the vial? (Use a preceding zero if it applies. Do not use trailing zeros. Round to the nearest tenth)

Step 1: Calculate the total dose required. The ordered dose is 10 mg/kg for a 90 kg client: 10 mg × 90 kg = 900 mg Step 2: Determine the concentration of the available drug. 1 gram = 1000 mg is diluted in 12 mL, so the concentration is: 1000 mg / 12 mL Step 3: Set up the proportion to find how many mL contain 900 mg. (1000 mg / 12 mL) = (900 mg / x mL) Step 4: Cross-multiply and solve for x. 1000x = 900 × 12 1000x = 10,800 x = 10.8 Answer: 10.8 mL
