All the other answer choices make you come across as an asshole. Easy way to ace ethics questions is to just not be an asshole
I would be a bigger asshole when the family came I'n after I pulled the plug...opps...but the friend said
The patient has no wife, children, or close relatives...
@lispectedwumbologist this is going to be my technique, because I've gotten a couple of these wrong, but I completely agree with everyone else's sentiments of suspicion of going off what a friend said without any confirmation about state of advance directives, etc. It's really dumb.
With these questions; you have to take what NBME says at face value. If it says no family, he really does have no family. This friend is also claiming that the 78 y/o said this about himself, so we know it's the patients wishes rather than someone else's wishes for him. (A son saying he can't let go of his father yet despite the patient's DNR type of situation).
I think the point here isn't that we would take the patient off the ventilator because the friend said so. The answer is saying "Thank you for your input, we will take that into consideration." It's completely non-committal.
they say no close relatives, which means he could have remote relatives, relatives must be asked before listening to a stranger/friend's words.....
Because you'll see some blast cells in a leukemoid reaction. It won't be 0%.
Also, don't get confused with 0% Basophils. Basophils are seen in CML but not in Leukemoid reactions. I just went with LAP because they pointed it out in the lab values. Had that not been there, I would have chosen "0% basophils"
the "left shift" you see in leukomoid reaction actually is describing the increase in immature leukocytes on CBC. that is why the LAP is important to be able to distinguish them
I agree, I picked H1 because such a common complaint for those on TCAs is Sedation, I figure it might be so commonly seen as to be the "most common" reason for noncompliance. I suppose the "hot as a hare...etc" effects would be more severe/annoying, but I didn't think they were more common.
I just like to pretend that there's a reason this question is now in an NBME and no longer being used for the test. Hopefully they realized the idiocy of this question like we all do
Since it said cyclic, I thought of using, discontinuing, then using again. These people who write these questions need take some English writing courses so they can write with CLARITY. Cyclic is not the same as Tricyclic.
Incredibly awful question. one thought I did have when deciding between anticholinergic and antihistaminic - nortriptyline and desipramine are secondary amines that have less anti-cholinergic effects (from Sketchy Pharm) so maybe that's what they were getting at? That someone went out and made a new TCA drug that would have less anticholinergic effects.
This isn't testing drug epidemiology; it's actually asking "which of these side effects are caused by TCAs and would be the worst to experience?"
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!
Ahhh yes the classic Glucosamine from fructose 6-phosphate question....Missed this question harder than the Misoprostol missed swing
no idea. i could only safely eliminate carbamoyl phosphate because that's urea cycle
just adding in to say, nope.
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
if this isn't a globe rupture than idk what is tbh
the air in the center of the globe made me think rupture too .....
There may be some global rupture, but impairment of one of the ocular muscles causing diplopia would still be the best explanation for this patient's double vision.
Globe rupture leads to entrapment of the IR muscle which causes diplopia. The question is asking what is causing his visual complaints, which is diplopia, not loss of vision.
only if it's an interstitial lung disease i believe. like polio can cause a "restrictive lung disease" but it's due to muscle effort and would expect to see a decrease in diffusing capacity (FA 2018 pg 657.2)
Construction worker, Diffuse reticular opacities screamed restrictive and low DLCO for me. Anything that either adds fibrosis to alveoli, or thickens the diameter between alveoli and alveolar capillaries will cause low DLCO.
Actually polio is one of the restrictive lung diseases that have a normal diffusing capacity for carbon monoxide (FA 2019 p.661)
I agree that it's confusing but I looked at it as a physical *obstruction* since it's impinging on the airway.... but yeah idk this is weird
Doesn't the trachea have cartilage rings so it wouldn't collapse which makes it seem less like a typical obstructive disorder? I'm really not sure why FVC would change because I don't see how total lung capacity or residual volume would change because those are static conditions where there is no airflow at all. I understand FEV1, peak expiratory flow, peak inspiratory flow etc.
Agree this is a really tough Q but I also think I really over thought it... I eliminated all with a normal Ratio bc something obstructing would obviously produce an obstructive pattern although I don't know why FVC would be decreased. I wasn't sure about both peak expiratory and inspiration flow being decreased can someone help me with this or tell me I'm totally overthinking again.. are they both decreased simply bc theres an obstruction ..?
Yea I got confused on this question. But I guess they wanted us to look at it as a obstructive disease . If this were the case all of those function tests would dec. ( See FA )
Because the obstruction is above the alveolar regions there is a decrease in air flow, not lung volumes, which would make this an obstructive pathology.
FVC here dec same way it dec in Obstructive lung disease. Read the concept of Equal pressure point of BnB. There he says in bronchitis we have onstructive pattern because inflammed airways gen more resistance. so EPP comes early. I guess here due to tracheal narrowing pressure inc downstream. which collapses smaller airway. result in air trapping.
