How is one supposed to know this before having read this article?
This question falls under the either you know it or you dont category. It isnt in FA or Uworld
So why would these A-holes put it on there as if prepping for this exam isn't stressful enough :-|
and there's so much unnecessarily BS instead of real questions
Meanwhile, I thought everything was wrong so I went with another Mature defense mechanism.
lol i thought it was some kind of urinary retention problem and put H.
How is H wrong? Oxybutinin or tolterodine treat urinary incontinence by blocking M3 muscarinic acetylcholine receptors --> urinary retention. We're just supposed to assume they are talking about BPH here because he is old?
I agree. I picked "H" for that same logic. Does anyone know where we should have come to the conclusion that this was BPH?
they are telling you he's having "difficulty urinating", one of the clinical criteria for BPH is reduced urinary flow rate. this is not incontinence because they are not telling you he leaks at all, just that he pees "a lot"
Even if he was urinating too much, anticholinergics are contraindicated in the elderly (Beers criteria)
@drzed tI mean techinically alpha-1 blockers are on the Criteria too ...
you're definitely not alone lol
And its not in FA, so fuck it IMO
I guessed it because the names sounded similar :D
I also guessed because both words start with "glu")))
same as person above me. also bc arginine carbamoyl phosphate and nag are all related through urea cycle.
Not a clue. This was so random.
this made me feel a lot better.
also, no fucking clue
My immediate thought after reading this was "why would i know this and how does this make me a better doctor?"
Generally speaking Glutamine is often used to aminate things. Think brain nitrogen metabolism. You know that F-6-P isn't an amine, and that Glucosamine is, so Glutamine isn't an unrealistic guess.
yea, I mature 30k anki cards to see this bs
I literally shouted wtf in quiet library at this question.
Lol def didn't know it. Looks like I'm not going to be a competent doctor because I don't know the hexosamine pathway lol
Is it biochemistry? Then I do not know it.
I Ctrl+F'd glucosamine in FA and it's not even there lol
i definitely guessed, for some reason got it down to arginine and glutamine
I did not
Narrowed it down to Arginine and Glutamine figuring the Nitrogen would have to come from one of these two but of course I picked the wrong one. Classic.
+1 no idea!
