Do nurses use math on the job?

Yes, you will need math skills.

Yes, definitely! If you are in a critical care area you will have to know the pharmacology of the drug and then make sure an infusion rate is correct. Especially important if you are “titrating to response” for example a target heart rate or blood pressure parameter.

Ues. Ideally when hanging drugs on patients you should be verifying that you are giving the right dose- kind of like a pharmacy double check!

Yes but you can use calculators and verify stuff with coworkers and/pharmacists until you get confident in your own calculations. I use math when I need to do partial doses and need to figure out how many milliliters i need depending on milligrams ordered and based on the concentration of mg/ml.
