To compound a custom solution, you are asked to add 10mg of drug to a 500ml bag of 5% dextrose injection. the drug is available in pre mixed bottles of 0.5% solution. how many ml should you add

2 mL

Step-by-step explanation:

If the drug is mixed in a solution of 0.5%, it means that for each ml of the solution, there is 0.5% or 0.005 grams of the drug. In order to get 10 mg of the drug, the volume required is:

You should add 2 mL of the solution.

*Note that the volume of the bag should not be used since the amount of drug needed was specified in weight and not in concentration.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
