A preparing to administer vancomycin 500 mg via intermittent IV bolus to a client. Available is vancomycin powder for injection 1 g vial. The nurse reconstitutes the powder for a final concentration of vancomycin 5 mg/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.)

Determine the desired dosage: The nurse needs to administer 500 mg of vancomycin. Determine the volume per dose: The concentration of the vancomycin solution is 5 mg/mL. The nurse needs to administer 500 mg per dose. To find the volume per dose, we can set up a proportion: 5 mg / 1 mL = 500 mg / x mL Cross-multiplying gives us: 5x = 500 Dividing both sides by 5, we get: x = 100 mL
