I'm just adding the page number from FA 2019 to this comment. FA 2019 page 625.
At the end of the fourth week, the yolk sac presents the appearance of a small pear-shaped opening (traditionally called the umbilical vesicle), into the digestive tube by a long narrow tube, the vitelline duct. (Wiki)
What a weird question. I could definitely hear a fixed split heart sound. And it was loudest over the pulmonic valve too which makes it even more of a dirty question. But I guess what I was actually hearing was an S3 heart sound.
@the260guy I believe the splitting is being heard only during inspiration, making this normal physiologic splitting. Perhaps that's just my ears.
don't have adobe and couldn't download it, so I just chose whatever, but your explanation suddenly makes me feel dumb but grateful! Loving your tips! @benwhite_dotcom
Exactly!! it's an autosomal dominate disease!
Autosomal dominant diseases are variably expressive. Still, I think this was a badly written question (should have given us some family history).
Also, FA says that fractures may occur during the birthing process, which is what I believe they were going for. I don't believe these findings would be seen at birth with any of the other choices.
Yeah I thought I outsmarted NBME by selecting Rickets bc it said no family history ... guess I got played lol.
This has to do with Intention-to-treat analysis. Essentially, when participants are non-adherent but the data shouldn't be lost. They just undergo another statistical model to account for their changes.
Here is a nice video
Where does the question mention "intention-to-treat"?
They seem to be pretty obsessed with "intention-to-treat" it's been asked in one way or another in all the new NBMEs that I've done. (Haven't done 24 as yet)
They don't, intention-to-treat is just the best way to go about it @dr.xx
I agree with @notadoctor !!
Standard lab values are incorrect, way to go NBME.
I think they mean to put mm Hg. Normal CSF pressure is about 100-180 mm H20 which equates to about 8-15 mm Hg.
I lost a bit of time wondering about that ugh lol
I thought there must be an obstruction in the ventricles somewhere preventing csf from getting to the spine. so pressure is low in spinal tap but in the head it must be really high.
Can't be 17α-hydroxylase because this would present with hypertension and some sort of ambiguous sexual presentation (males) or lack of secondary sexual development (females). Can't be 11β-hydroxylase because this would present with the opposite of the kid's presentation due to the production of 11-deoxycorticosterone (similar effects to aldosterone but not nearly as potent). The other two would not really make sense since there are increased levels of 17-hydroxyprogesterone.
Correct, you would not want to give fibrates to someone with recurrent pancreatitis since fibrates increase the risk of cholesterol gallstones due to inhibition of cholesterol 7α-hydroxylase.
FYI @gh889 can't follow your link w/o an NYIT username and password, unless there's a more tech-savvy way around that.. I appreciate the info, though. Niacin rx for familial hypertriglyceridemia w/ recurrent pancreatitis. Now I know..
Great points, very in depth knowledge taking place here. Also, familial hypertriglyceridemia (per FA 2019 pg 94) has hepatic overproduction of VLDL so picking this would have been the easiest answer (in retrospect)
@impostersyndrome1000 literally that's the ONE thing i remembered and i went YOLO lol cuz i was staring for a while
