Drug reconsitition problem

[BEBE1004]

an order reads "drug a 50 mg iv every 8 hours." the pharmacy sends a powdered vial labeled "drug a 1 gram-add 10 ml normal saline for reconstitution." how much solution should the nurse administer to obtain a 50 mg dose? (round to one decimal place, include units without spaces).

you have a drug that when reconstituted equals 1 gram in 10 ml so to calculate you can use the formula desired / have x quantity.

50 / 1000 (convert 1 gram to mg) x 10 = 0.5 ml

this is very basic question and can actually be figured out in your head. 1000 mg total, 10 ml of solutions so you know its 100 mg / ml.

i would have to know the resultant volume, may not be 10 ml.

I agree it may not be 10 ml, but working within the info that was given as it sounds like a text book question.

Absolutely the answer is 0.5ml. There is no trick here, it's textbook. The drug powder will absorb into the 10ml it willnot cause your volume to be greater than 10ml. I can understand why you might ghingg that but its0.5ml of aa 100mg/ml solution.
