Heparin Drip Protocol Calculations


Heparin Drip problems are extremely confusing when you start doing them. It took me a long time to actually understand what I was doing on these. I found this video on how to do the calculations. This guy does a fantastic job explaining the process from beginning to end. The only thing that I do not agree with is the fact that he only rounds the mL/hr to the 10ths place for an IV pump. Our school teaches us to round to a whole number whether it is gtts/min or mL/hr.

Tube Feeding Calculations


I don’t know about everyone else, but I have had an extremely difficult time figuring out Tube Feeding type problems. I don’t know why, but I have. However, after viewing the video below, I now feel really dumb. This instructor makes doing these problems seem like child’s play. It is so, so easy now, and I think that I can remember this for future tests.

Advanced IV Nursing Calculations


I have several IV dosage calculation problems that I had to do for my class. As everyone knows, I am a Dimensional Analysis girl. If it wasn’t for learning and using this method, I am not sure I would ever be able to remember all of the formulas involved in nursing calculations. I am posting the problems with my answers worked out by Dimensional Analysis. Having them posted like this allows me to take them with me wherever I go. I can even pull them up on my phone and study them like that. It makes my life so much easier. I guess everyone can tell by now that I am more of a computer person than the paper and pen type.

Heparin Drip and Heparin Titration


Heparin Drips can be intimidating. Here are a couple of tools I have used to learn how to do these types of IV calculation problems.

This is a video that explains the calculation process in an easy to understand manner:


This is my Dimensional Analysis way of working out a problem using the Heparin Protocol:


Below is a the Heparin Nomogram that the girl in the video is using:

Learn Dimensional Analysis


Here is a video that does a great job on explaining Dimensional Analysis. Although it is talking about it for Chemistry purposes, the same principal still applies for nursing drug calculations. This is probably the best video that I have seen on explaining this method.
