Pharmacology HELP!!!

[mrjinlove0913]

I guess it has been a long time. I am needing help in two areas. One how to calculate Body surface area???

Here is a pharm question and I am lost.

A dose of 500 mg in a volume of 3 mL ir ordered to dilute 55 mL to infuse over 50 minutes. A 20 mL flush to follow.

What is the dilution volume?

How many gtts/min should the IV infuse at? Microdrip?

mL HOUR?

ANYONE WITH AN UNDERSTANDING PLEASE HELP

The problem is not very clearly written, but my best guess would be as follows:

Dilution Volume: 3 mL + 55 mL =

58 mL

Infusion Rate:

55 mL/50 minutes

(infusion rate)

x 60 gtts/mL

(drop rate of microdrip tubing)

=

66 gtts/minute

(infusion rate) to be followed by the 20 mL flush
