HHV8 belongs to Herpesviridae family. Is it true that all members of this family have multinucleate cell with intranuclear inclusion body? HSV and VZV(cowry type A inclusion), EBV and CMV(owl-eye internuclear inclusion) certainly have them. Did anyone pick E for this reason?

I have read all the comments, but none explain why hyponatremia is wrong. There is definitely Na+ in stool....thats why sugar+salt is rehydration for peds diarrheal sickness. Low Na+ causes low EVV explaining the low BP, high HR, pallor, and dehydration. Is it correct but just not as correct as C?

waterloo  I Dont know what you mean by low EVV. But here's my thought process. This pt lost lots of water, and when someone takes a laxative causing them to have diarrhea that will lead to metabolic acidosis. A buffering mechanism for the decreased bicarb in the blood is for H+ to leave cells and K+ to go into the cells. So he has to have hypokalemia (low K+ in serum). They gave him IV fluids, so his BP should be headed back to normal. I would think his RAAS will chill out. But it takes time to correct the acidosis, you're kidney won't just immediately stop reabs bicarb so you're body will still be buffering against the acidosis (H+ out of cell, K+ in). +  
waterloo  sorry, I wrote increased bicarb, I meant DECREASED bicarb in the blood. And also should have written "you're kidney won't just immediately START reabs new bicarb" My Bad, wasn't trying to add to confusion. +  
drdoom  i think by `EVV` author meant `ECV` (extracellular volume). @waterloo, appreciate the explanation but think something is off: loss of HCO3- via diarrhea should result in acidemia, which would oppose the presumption of ‌``H+ leaving cell, K+ going in´´. +  
waterloo  hey so sorry, I must have been super tired posting this. Can't believe I made so many mistakes. Read over it again, and it sounds like gibberish. Wish there was a way to delete. My bad. +  
waterloo  I think I tried to explain too hard. Looking at this question again, I think really the only this is when you lose that much volume, you lose bicarb and K+. Nothing really to do with acid-base. My b. +  
drdoom  no worries! +  
castlblack  EVV = effective vascular volume. Thank you for trying to help but I still don't understand. I still agree with my above mechanism as correct. Whether or not it's most correct idk. +  
amy  what about the long steamy bath? He also sweat a lot, and profuse sweating is going to cause hyponatremia? +

nlkrueger  i did not lol +  
ht3  you're definitely not alone lol +  
yotsubato  no idea +  
yotsubato  And its not in FA, so fuck it IMO +1  
niboonsh  i didnt +  
imnotarobotbut  Nope +  
epr94  did not +  
link981  I guessed it because the names sounded similar :D +14  
d_holles  i did not +  
yb_26  I also guessed because both words start with "glu"))) +27  
impostersyndromel1000  same as person above me. also bc arginine carbamoyl phosphate and nag are all related through urea cycle. +1  
jaxx  Not a clue. This was so random. +  
ls3076  no way +  
hyperfukus  no clue +  
mkreamy  this made me feel a lot better. also, no fucking clue +1  
amirmullick3  My immediate thought after reading this was "why would i know this and how does this make me a better doctor?" +8  
mrglass  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. +4  
djtallahassee  yea, I mature 30k anki cards to see this bs +4  
taediggity  I literally shouted wtf in quiet library at this question. +1  
bend_nbme_over  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 +21  
drschmoctor  Is it biochemistry? Then I do not know it. +5  
snoochi95  hell no brother +1

bodanese  I did not +  
hatethisshit  nope +  
jesusisking  I Ctrl+F'd glucosamine in FA and it's not even there lol +  
batmane  i definitely guessed, for some reason got it down to arginine and glutamine +2  
waterloo  Nope. +  
monique  I did not +  
issamd1221  didnt +  
baja_blast  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  
amy  +1 no idea! +  
mumenrider4ever  Had no idea what glucosamine was +  
feeeeeever  Ahhh yes the classic Glucosamine from fructose 6-phosphate question....Missed this question harder than the Misoprostol missed swing +1  
surfacegomd  no clue +  
schep  no idea. i could only safely eliminate carbamoyl phosphate because that's urea cycle +  
kernicteruscandycorn  NOPE! +  
chediakhigashi  nurp +  
kidokick  just adding in to say, nope. +  
flvent2120  Lol I didn't either. I think this is just critical thinking though. The amine has to come from somewhere. Glutamine/glutamate is known to transfer amines at the least +1
