Question

Quizplus · Accepted Answer

To determine the amount of medication to be drawn, we first need to find out how many milliliters (mL) are needed for 250 mg of medication.

We can set up a proportion as follows:

250 mg/1.5 mL = X mg/ Y mL

Cross-multiplying gives:

250 x Y = 1.5 x X

Solving for X (the amount of medication to be drawn in mg):

X = (250 x 1.5) / 1

X = 375 mg

So we need to draw up 375 mg of medication. However, the available medication comes in a concentration of 250 mg/1.5 mL.

To find out how many milliliters to draw up, we need to set up another proportion:

250 mg / 1.5 mL = 375 mg / Y mL

Cross-multiplying gives:

250 x Y = 1.5 x 375

Y = (1.5 x 375) / 250

Y = 2.25 mL

Since we need to draw up 2.25 mL of medication to get 375 mg, we can round up to the nearest tenth of a milliliter, which would be 2.5 mL.

Therefore, the answer is choice C, 1.5.
