Knowing math will help you as a nurse. But the math is also pretty basic math such as figuring out IV rates, dosages, etc. which are pretty much ratio and proportion problems. Once you are in nursing school they will drill nursing math into your head, I know my school did. Now I am confident with math used i=as a nurse. But here is the thing, ever since I started my job as a nurse, math is usually already done for us and is stated in the orders exactly the rate we need to set an IV pump at, and the dosage we need to give. I rarely need to double check any math already done for my meds unless I really suspect something is off. There are so many more challenges in nursing other than the math honestly (not to scare you), but trust me math will probably be the lesser of your worries when on the job.
