Question

The health care provider prescribes meperidine 60 mg and atropine sulfate 0.4 mg intramuscularly. The medications are compatible and will be mixed into one syringe. The label on the prefilled meperidine syringe states 100 mg/mL. The label on the prefilled atropine sulfate syringe states 0.4 mg/mL.
How many milliliters of meperidine and how many milliliters of atropine sulfate will be prepared for administration?

Answer 1

Answer : The volume of meperidine and atropine sulfate prepared for administration will be, 0.6 mL and 1 mL respectively.

Explanation :

As we are given that the label on the prefilled meperidine syringe states 100 mg/mL. Now we have to determine the volume of meperidine will be prepared for administration.

As, 100 mg of meperidine prepared for administration in = 1 mL

So, 60 mg of meperidine prepared for administration in = $\frac{60mg}{100mg}\times 1mL=0.6mL$

and,

As we are given that the label on the prefilled atropine sulfate syringe states 0.4 mg/mL. Now we have to determine the volume of atropine sulfate will be prepared for administration.

As, 0.4 mg of atropine sulfate prepared for administration in = 1 mL

So, 0.4 mg of atropine sulfate prepared for administration in = $\frac{0.4mg}{0.4mg}\times 1mL=1mL$

Thus, the volume of meperidine and atropine sulfate prepared for administration will be, 0.6 mL and 1 mL respectively.
