infusion problem #12 quiz 10

I just can't seem to solve an infusion problem when I don't know the amount to put over the hours. See problem below:

The physician orders an IV infusion of D5W to run at 60mL/hr with a drop factor of 15gtts/mL for 24 hours. How many 1L bags of D5W will be required for this infusion?

A. One

B. Two

C. Three

D. Four

Could someone please show me the steps in solving this problem. Thanks. My PTCB exam is this March 31st.

I think you're not decoding the question, or possibly overthinking it. Here's what I'm seeing:

The physician orders an IV infusion of D5W to run at 60mL/hr with a drop factor of 15gtts/mL for 24 hours. How many 1L bags of D5W will be required for this infusion?

The drop factor is just thrown in to try and fool you

So,

60mL X 24 hours = 1440mL

1440ml ÷ 1L bags = 1.44 Bags

You'd need 2 bags.

 Mar 27, 2011 overthinking problem #12 quiz 10 by: Sheila Yes, after more thought and rereading the question again I realized it was not asking for an infusion rate. I have read your suggestions how to approach math problem so I just have to make myself follow that approach. Thanks for all your help.
