The physician orders Torodol 60 mg injection. The label reads 20 mg/ml. How many ml should you give? Show all work using dimensional analysis

Answer 1

To calculate the number of ml to give, we need to set up a dimensional analysis using the given information:

1. Start with the ordered dose: 60 mg
2. Use the label information to convert mg to ml: 1 ml = 20 mg

Now let's set up the conversion factor:
(60 mg) x (1 ml / 20 mg) = 60/20 ml = 3 ml

Therefore, you should give 3 ml.
