I start ASU's nursing program on monday. I just finished my last semester of generals, which included pathophysiology. I've been told by professors and nurses I know, and I have read from post online, that your understanding of pathophysiology is one of the most influential factors in clinical settings both during the nursing program and after graduation. However, I left patho feeling quite uneasy. I really don't know how I managed a B in that course. If I was asked any information about that class right now, I probably wouldn't be able to answer with confidence, if at all. This was in part because of my bad stress management this last semester, and because it was just much different than anything I'd taken before. Despite the class being the most interesting course I've ever taken. So, since I've passed the course and got into the program, and don't really have time or the opportunity to retake it. What ways can you guys/gals recommend to reinforce/reteach myself pathophysiology? Is it just a matter of studying textbooks/patho concept books? Are there online programs? Is it really not that big of a deal, and the nursing program itself will reinforce those concepts as I go along (One could only hope lol)? Thank you in advance for any and all advice :)
