So, for the NMBE tests, I've noticed that sometimes the questions are hard to discern cause and effect. Here's just an example I'm making up:
What physiological values would be seen in someone with Vitamin D deficiency:
A. Ca2+ down, PTH up, calcitonin down, increased renal Ca reabsorption, increased osteoclast activity
B. Ca2+ down, PTH down, calcitonin up, decreased renal Ca reabsorption, decreased osteoclast activity
C. Ca2+ up, PTH up, calcitonin down, increased renal Ca reabsorption, increased osteoclast
This is the best I can come up with, but I'm not capturing the nuances well enough to really give a good example of what I'm talking about.
Basically I never know where exactly to distinguish cause and effect. Do we start with Ca2+ down, and then assume that PT increases to counteract that? Or if they say Ca2+ up, do they mean [Ca2+] is increasing due to PTH?
I hope I'm expressing myself clearly, or at least some of you will know what I'm talking about, and maybe come up with a better, more nuanced question, because this one isn't quite as tricky as I would like it to be.
