I had an assignment with 25 questions did the rest these have me stumped so if you happen to be good at math I would greatly appreciate the help. Even if you just tell me how to figure them out and I do the rest.Anything...

A. Normodyme (labetalol HCL) 20 mg IVP slowly over 2 minutes

The label reads 5 mg/ml. How many milliliters of this antihypertensive (calcium channel blocker) will the patient receive per minute?

B. Your patient has meningitis.

Order: Pfizerpen (Penicillin G) 600,000 units IVPB q 4 hours

The directions are as follows:

Amount of diluent

concentration

20.0 ml

50,000 u/ml

10 ml

100,000 u/ml

4 ml

250,000 u/ml

1.8

500,000 u/ml

What is the best dilution to choose and how much of this antibiotic will you draw up?

Egads!!! I'm not looking forward to math....

I know it's tough but if I can do it you can, trust me!:p
