A patient is prescribed an IM dose of 80 mg of a psychotropic medication that comes in a concentration of 40 mg/mL. How much of the medication should you draw into the syringe per dose?

A. This would only provide 40 mg, which is exactly half of the prescribed 80 mg dose. B. Step 1: Use the formula- Volume to administer (mL) = Desired dose ÷ Concentration. Step 2: Insert known values (Desired dose = 80 mg, Concentration = 40 mg/mL). Volume to administer = 80 ÷ 40 = 2 mL. C. This would provide 120mg (40 X 3), which is a significant overdose. D. This would provide 60 mg (40 X 1.5), which is 20 mg short of the required dose.
