The doctor orders Valium 2.5mg IM. On hand you have Valium 5mg per ml. How many ml do you prepare for this patient? Show the steps to how you got the answer?

D/H x V = amount to give (this is our formula to find out our drug calculation)

Dose you want to give / Dose on hand x vehicle = amount

So, let's plug in our numbers for our equation:

The dose we want to give is 2.5mg

Those dose we have on hand is 5mg/1mL

It's in a 1mL "vehicle" ... We'll set up the equation now.

2.5mg / 5mg x 1

2.5 : 5 = 0.5

0.5 x 1

So, you'll want to give. 5mg for this patient.
