Lol, I couldn't really figure this question out so I was like F it. Coronavirus it is.

The question clearly lead us to think about Osmotic pressure by talking about protein and urine. I wonder how many people used that line of reasoning (like myself)?

Great explanation, I chose lymphatic drainage for the same reasoning (similar Q on different bank)

My reasoning was much more simplistic (maybe too simple) but in my mind, systolic BP is determined by Cardiac Output and diastolic BP is determined by arterioles. Therefore, what comes before the capillary and regulates resistance? Arterioles. That's why I said that pre-capillary resistance.

the main difference between the 2 cases is that in this case the patient has high BP

So in kindergarten language the question is essentially asking how high pressure in the arterial system is NOT transmitted to the venous system (which is where EDEMA develops). But you know they have to add all this info to try confuse a basic principle and make you second guess yourself. (Got it wrong by the way) because of what @ferrero said of Qbank questions.

hello
@ferrero what are you talking about? lymphatic drainage is the wrong answer...

ok never mind. i got it. hard to understand b/c it was a big block of text.

I think they may be talking about the myogenic compensatory mechanism: https://www.ncbi.nlm.nih.gov/books/NBK53445/figure/fig4.1/?report=objectonly
"Increased arterial or venous pressure also induces myogenic constriction of arterioles and precapillary sphincters, which raises arteriolar resistance (thereby minimizing the increase in capillary pressure) and reduces the microvascular surface area available for fluid exchange.
For example, because vascular smooth muscle in arterial and arteriolar walls contracts when exposed to elevated intravascular pressures, this myogenic response increases precapillary resistance and protects capillaries from a concomitant rise in their intravascular pressure."

makes sense. sometimes we use vasodilation(CCB) + venodilation (ACEI) combo to balance the pressure, and prevent leakage and edema.

How are you supposed to remember which S is which?

@drzed "Supra" = on top, so the 1st S is for supraspinatus.

patient has malaria with obvious picture and clinic, i answered because only thing associated with liver was hypoglycemia

I was thinking that she is hypotensive which can cause an infarct of the pituitary (since pituitary is growing during pregnancy) and therefore she'd have secondary adrenal insufficiency.

me also :/ sitting there trying to figure it out during the test I thought I was so smart too - like "wow nbme, way to tie in micro and endocrine, not getting me though!" ... i was wrong.

And here I was thinking that maybe I'm the Lionel Messi of interpreting stems by diagnosing it as Babesiosis lols.

quarantined at home during the coronavirus pandemic and selecting the right answer as CoRona without thinking twice as i use the sanitizer to kill those little bastards knowing they are enveloped..wow what has life become
