Question

the nurse is preparing to administer streptomycin 0.25 grams, directions say to reconstitute with 9 ml sterile water for a concentration of 400 mg/2ml. how many ml do you administer?

Answer 1

To administer streptomycin 0.25 grams at a concentration of 400 mg/2ml, the nurse should administer 1.25 ml of the reconstituted solution.

Step-by-step explanation:

To administer streptomycin 0.25 grams, the nurse needs to reconstitute it with 9 ml of sterile water. The concentration of the reconstituted solution is 400 mg/2ml. To find out how many ml to administer, we need to convert grams to milligrams to match the concentration units. 0.25 grams is equal to 250 milligrams. Since the concentration is 400 mg/2ml, we can calculate the total volume to administer by cross-multiplying:

(400 mg / 2 ml) = (250 mg / x ml)

Solving for x gives:

x = (250 mg * 2 ml)/400 mg

x = 1.25 ml

Therefore, the nurse should administer 1.25 ml of the reconstituted solution.
