First of all nurses making comments and getting upset about other nurses working out the problem. You need to relax! First of all this student is trying to learn and trying to work out a math problem!!!!!!!😈 As a RN, former student. Every nurse used examples from math problems to learn and work out future problems. Even as a nurse now I have to refer to examples or get stuck on some math problem while furthering my education. Even doctors can't figure out some of the math in our in-house hospital test! It's not about working out the problem for someone. It's showing someone step by step how they worked out that particular math problem so they can work out the next problem. Giving them links is helpful of course but they might not have that exact problem. The fact that this student is coming on here to ask for help shows initiative And wanting to learn.
