The nurse would administer 1.3 mL of penicillin G benzathine.
Desired dose: 400,000 units
Available concentration: 300,000 units (Units) per 1 mL (Volume)
(Desired dose ÷ Available concentration (units)) × Available dose concentration (volume) = Milliliters per desired dose
(400,000 units ÷ 300,000 units) × 1 mL = 1.3 × 1 mL = 1.3 mL
