A nurse is preparing to administer vancomycin 500 mg via intermitent 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 tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["100 mL"]

First, we need to determine how many milligrams of vancomycin are in each milliliter of the reconstituted solution:

1 g = 1,000 mg

If we reconstitute 1 g of vancomycin powder for injection in enough diluent to make a final volume of 200 mL, the concentration will be:

1,000 mg ÷ 200 mL = 5 mg/mL

Now, we can calculate how many milliliters of the reconstituted solution the nurse should administer to deliver 500 mg of vancomycin:

500 mg ÷ 5 mg/mL = 100 mL

Therefore, the nurse should administer 100 mL of the reconstituted vancomycin solution via intermitent IV

bolus.

Correct Answer is ["2 mL"]

Explanation

To calculate the volume to be administered, the nurse should divide the prescribed dose (200 mg) by the

concentration of the available medication (300 mg/3 mL): 200 mg / (300 mg/3 mL) = 2 mL.

Correct Answer is ["100 mL"]
