A nurse is preparing to administer ampicillin 500 mg IM every 6 hr. The available ampicillin is in a 500 mg vial.
The package insert instructs to add 1.8 mL of sterile water to yield ampicillin 250 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.)
