# Ordered 1000 ml lr at 50 gtt/min (20 gtt/ml tubing) what is the total time to infuse

Next figure out how many mg the patient needs.Multiply 3 times 40 = 120 mg.This patient needs 120 mg every 4 hours.Finally, figure out the quantity needed.I wish I could show this properly!......
here are a few more I don't understand.. I have alot of my answers that I worked out my self but these ones I am stomped on..
a)1500 ml d5w at 80ml/hr using an infusion pump, what is the total time to infuse
b)order elixophyllin 3mg/kg every 6 hours, patients weight is 88lb, supply is elixophyllin 80 mg per 15ml, how many ml do I give?
c)ceclor oral suspension 20mg/kg/day in 3 equally divided doses, patient weighs 20lb, subbly ceclor 125mg per 5ml, discharge instructions: give__ t three times a day

a) This is simply 1500 divided by 80. Which equals 18.75 hours. Which is 18 hours and 45 minutes.
b) First, figure the patient weight in kilograms. 88 lb divided by 2.2 = 40 kilograms. Next figure out how many mg the patient needs. Multiply 3 times 40 = 120 mg. This patient needs 120 mg every 4 hours. Finally, figure out the quantity needed. I wish I could show this properly! The equation goes like this:
X ml 15 ml
-------- = ----------
120 mg 80 mg
Anytime you move across the equal sign you have to switch places. X is on top, leave it there. You want the X by itself. So, move the 120 to the other side. In order to do that, the 120 mg has to go from bottom to top. So you are left with this:

X = 15 mg times 120 mg
------------------------------
80 mg

Now
X = 1800 (which is 15 times 120)
----------------------------------------…
80

so
X = 22.5 ml

Therefore, the patient needs 22.5 ml every 6 hours.

c) You can figure this one out based on the answer in b). And you need to. This is very important stuff and must be understood in order to properly perform whatever duty it is you are studying for. So, I won't give you the direct answer to that. Look at and understand b). If you can't you need to speak with someone that can explain it to you in detail until you understand it.

Best of luck!
