You mix a powder drug with a 4.5ml of liquid to get a reconstituted solution with a concentration of 250mg/ml. The prescribers order is for 500 mg . You will give what ml of the reconstituted solution

STEP BY STEP SOLUTION: To find out how much of the reconstituted solution to give, you can use the formula: \[ \text{Volume} = \frac{\text{Amount of Drug}}{\text{Concentration}} \] Given: - Amount of Drug (A) = 500 mg - Concentration (C) = 250 mg/ml Substitute these values into the formula: \[ \text{Volume} = \frac{500 \, \text{mg}}{250 \, \text{mg/ml}} \] \[ \text{Volume} = 2 \, \text{ml} \] ANSWER: So, you would give 2 ml of the reconstituted solution to meet the prescriber's order of 500 mg.
