A nurse is preparing to administer metronidazole 7.5 mg/kg via intermittent IV bolus to a client who weighs 212 lb. Available is metronidazole 500 mg/100 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the client’s weight from pounds to kilograms Weight = 212 ÷ 2.2 ≈ 96.4 kg Calculate the ordered dose in mg Ordered Dose = 7.5 × 96.4 Ordered Dose ≈ 723 mg Identify the available concentration Available Concentration: 500 mg/100 mL Calculate the volume to administer Volume to administer = (Ordered Dose ÷ Available Dose) × Total Volume Volume to administer = (723 ÷ 500) × 100 Volume to administer ≈ 1.446 × 100 Volume to administer ≈ 144.6 mL Round to the nearest whole number = 145 mL
