Dose is 0.5 mg x kg

Child’s weight is in pounds, so we have to convert it to
kg
1 Kg = 2.2 pounds (lb)
X kg = 42 lb
X = 42*1/2.2 = 19 kg

So the dose is 0.5 mg x 19 kg = 9.5 mg
---------------- that’s the 1st part to get into the final part
of the question which is how many ml should be
administered? In other words, to get 9.5 mg delivered,
how many mL should be given?

The key answer is how much solution, ampule, syrup ….
you have (in other words, the fixed amount of medicine
that would be supplied for you from the pharmacy)

So here we have 25 mg / mL in each ampule, and we
need to give 9.5 mg, if you arrange it in an equation, it
will be:
25 mg ---- 1 mL
9.5 mg ---- x mL (x is always the missing amount that you need to know)

X = 9.5 x 1/25 = 0.381 --> round to nearest tenth = 0.4
