This is another video in my math for meds/dimensional analysis series. This one focuses on dosage calculation problems with three part equations.

Your step by step teaching and your going through each problem are the clearest and easiest to understand. By far the best out there. Thank you.

I’m glad I found this video, I start in nursing fall semester . We get 3x tired to pass. This helped a lot ❤

[marlisedeboer]

Fantastic! I have been trying to figure out dimensional analysis for a while. Your clarity and clear examples have been life saving! Thank you!

Just to clarify: when I say do the math/put it in your calculator I mean multiply the numerator (top numbers), then multiply your denominator (bottom numbers). Then divide the numerator total by the denominator total.

You literally just blew my mind. Thanks so much for being so clear and concise with your explanations

[carlisefarren]

Great job, Professor. Thank you! Your content is definitely building my confidence.

You have the best teaching videos of these by far! I'm starting nursing school in January and trying to get a heads up with the basics. I have a medical background as a Radiologic Technologist so that'll help me a lot I hope, but I'm still nervous. Will be watching more of your videos, thanks!

This has really been a wonderful asset. Thank you!

Just double checking...the second problem you did, I got 1.98. Your answer said 2 tablets...I assume you just round to a whole tablet...right? Pretty sure it's implied but you just didn't mention it. Does that happen often - that the answer is just a teensy bit off from a whole number and you just round up/down?

[bunmi]

Thank You for teaching this so well. I got this

[omgitsvioleta]

[applemacaraeg]

Thanks! Such a huge help. I hope to pass my exam next week.

So the questions where it's mL/hour over an IV drip. It said she's giving a 50mL dose. Wouldn't that overdose him? Or would the nurse take it away after 30 mins?

[myrat]

Not sure if you do this but I have an equation that I'd like to double check with you. The text answer is 2.08ml/min and my answer is 1.38 ml/min. This text has had several incorrect answers so I just want to make sure.
Here is the question:

KcL 10mEq and K Acetate 15 mEq in D5W 1000 mL is ordered to be administered over 8 hours. What would the rate be in mL/min?

Since we are looking for mL/min, this is how I set up the equation:

1000 mL x 10 mEq x 1 hr

15 mEq x 8 hrs x 60 min

Thank you.

What do I do when it asks for how many teaspoons to give

[beautyjourney]

When you say “now we just do the math, punch it in your calculator or do it in your head.” What math? Are you multiplying straight across? I watched your first video and I’m still not sure what to do after I set it up.
