I am just wondering how most people study their lab values? I've seen a couple of good posts about values for PT (preteen =10-14 -- that was good!) and the for for BUN. But I'm wondering what the best way is. I feel like that is my weakness. I have the lab value section in the little LPN notes flipbook that I keep going over but the little hints to remember really help. What do you think are important ones to remember? I'm sure RBC, WBC, PT, PTT, INR, BUN, H&H, Na, K+. What else would you consider key?
