I gave a lecture to the third-year medical students at Providence hospital on Friday. I thought the lecture went well but on saturday I was going over an admit note by one of the students in the class. The patient was admitted with DKA but had a combined metabolic acidosis and respiratory alkalosis. This student didn't do the Winter's formula calculation and missed the respiratory disease. Of course so did everyone else on the admitting team.
Here is the handout. I added a couple of things since giving the lecture on Friday.
Update: I corrected a mistake in one of the delta bicarb questions. Sorry.
