I don't know that you have to labor through all of the small details provided in Rapid Review about trace minerals (other than copper and Wilsons). I would definitely know the fat soluble vitamins (A, D, E, K) and what happens when they're lacking/in excess, which vitamin is deficient in breast milk (D), what the K dependent clotting factors are, and what deficiencies with the B vitamins look like and when you'd find them (pelagra for niacin, Wernicke's with B1/thiamine, certain drug interactions with B6, et cetera). It was a few weeks ago (hopefully getting score tomorrow! 😱) but I had at least 3 straight nutrition questions not counting those in hematology related to megaloblastic and iron deficiency anemias and all of the stuff about vitamin D and calcium in endo - which was fairly high yield on my test between the parathyroid glands, intestines, liver, and kidney!
