htballer55 Afferent artery dilation* +5

link981 There is decreased afferent renal artery dilation (less blood flow) leads to increased renin release from the juxtaglomerular cells (located near the afferent artery) to try to increase blood flow. I got it wrong but after reviewing saw my idiotic mistake. +1

generic_login I used that reasoning to pick C, but in looking it up now it seems like you are right ... There appear to be a bunch of mistakes on this test, and it’s not giving me a lot of confidence for the real thing. +

mee48 I think it is because NSAIDs inhibit the local prostaglandin (PGE2) in afferent arteriole —-> less AA dilation —-> stimulation renin release. I think my reasoning came from sketchy pharm nsaid video but I can’t 100% remember +

keycompany NSAIDs constrict the afferent arteriole. A. GFR would decrease due to decreased renal blood flow. B. Renal Blood flow would decrease. C. Renin would increase due to renal hypoperfusion. D & E. PGE2 and TXA would decrease (by MOA of NSAIDs). +9

fallot4logy UW says that Nsaids is one of the 5 drug categories that is able to cause hyperkalemia.Specificly ,Nsaids lower PG andrenin secretion .PGE2 stimulates JG cells to secrete renin...(how can i delete my previous unfinished message,lol?) +1
