Hey #nephrology mastodon (#nephrodon ?). My niece has just started medical school and she’s asking me, her “I-did-my-physiology-thirty-years-ago” Family Physician uncle, osmolality questions. Bless her. @ChristosArgyrop I think all options are wrong but what she has selected is least wrong(?) as I’d expect low osmolality.

@auscandoc High Urine Osmolality means that the kidneys are responding to the ADH and that the levels of the ADH is high. So her answer is correct

@ChristosArgyrop Thanks for replying…. For my own further education, the bit that is puzzling me is the normal serum osmolality. I interpret as as SIADH (but maybe it’s not?). I always (perhaps incorrectly?) assumed the low K (and Na) was due to the water overload. This why I expect the osmolality to be low in this scenario.
