A nurse is preparing to administer 250 mg of an antibiotic IM. Available is 3 g/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

The first step is to convert 250 mg to grams:

250 mg = 0.25 g

Next, we need to determine how many mL are needed to administer 0.25 g of the antibiotic.

3 g is equivalent to 5 mL, so:

0.25 g is equivalent to (5/3) * 0.25 = 0.4167 mL

Therefore, the nurse should administer approximately 0.4 mL per dose.
