Solutions

Expert Solution

USE THE BELOW FORMULA

Amount required=( Dose ordered x Total amount in ampule ) / Dose in ampule

Dose ordered = 0.25 mg

Total amount in ampule = 2 mL

Dose in ampule = 0.5 mg

substitute in the above formula

Amount required = (0.25 x 2 ) / 0.5 = 0.5 / 0.5 = 1 mL

So 1 mL of drug is required for ordered dose.

In simple terms,

0.5 mg = 2 mL

0.25 mg = X mL

Find X

X x 0.5 = 2 x 0.25 = 0.5

X = 0.5 / 0.5 = 1 mL
