mantarayrayI think that it's not ANP because ANP will cause a loss of Na but water will follow (they usually go together), whereas ADH will cause absorption of only water and will cause hyponatremia
except only thought this post getting the question wrong :")+12020-01-07T21:30:23Z
mantarayrayOops sorry the formatting is confusing: I think that it's not ANP because ANP will cause a loss of Na but water will follow (they usually go together), whereas ADH will cause absorption of only water and will cause hyponatremia. +12020-01-07T21:32:15Z
pg32@mantaray pretty sure you are right and that is the only way to get this question correct. Remembering that Na concentration really is a measure of water balance is key. If the pt is hyponatremic, that just means they have too much water in the blood, which is caused by ADH. If the patient was hypoVOLEMIC, that might mean they are losing too much Na.
This is illustrated by pts with SIADH. They are hyponatremic, but euvolemic, meaning that they have too much water (hyponatremia from the ADH) but their Na balance is ok (due to excretion of Na via ANP/BNP)+2020-01-25T17:53:48Z
almondbreezea concept continuously emphasized by uw, but I get always wrong :'(+2020-01-13T15:15:35Z
raffffwhy does the body make anp at all since its so useless+12020-01-17T08:02:10Z
makinallkindzofgainz@raffff - at least BNP gives us a good marker for heart failure exacerbations :) thanks body!+2020-01-25T20:42:49Z
hayayahApparently, in chronic CHF you see hyponatremia. Because CHF causes a decrease in cardiac output and circulating blood volume, which in turn triggers a compensatory response aimed at preserving blood pressure. This stimulates the body to retain both water and sodium. +32019-05-28T22:24:14Z
seagulli agree with Hayayah... the RAAS system is activated due to poor perfusion to the kidney due to decomp heart failure. +42019-06-01T03:32:28Z
hyperfukusif all else fails i hope i just drill this one statement in my brain and it comes out in the right way on test day thank u!!!+2019-08-10T07:33:37Z
jooceman739My thinking is that ANP causes natriuresis, so you're losing salt and water at the same time (isoosmotic fluid?). Meanwhile, ADH absorbs only free water, so it would dilute the serum.
Correct me if i'm wrong. +72019-06-08T21:42:02Z
bubblesOhhh you are right. Thank you for the explanation! I got so fixated on that one mechanism haha.+22019-06-08T22:03:55Z
trichotillomaniacHi Lauri, this is normal. We can't post the whole question due to copy right laws but you can almost always find the question you are looking for and the answer to by going to the form and then Ctrl + find -ing the age of the patient and other key words or the answer!+12019-08-10T23:11:46Z
drdoomHI LAURI. THANK YOU FOR DEMONSTRATING YOUR PROFICIENCY WITH ALL-CAP COMPOSITION!+22019-08-11T05:46:22Z
