These always tripped me up:
+ Polydipsia= responds to water deprivation, low serum Na
+ Central= responds to vasopressin, high serum Na
+Nephrogenic = responds to nothing, normal serum Na
lynnI think serum Na+ only depends on the patient's access to water. FA19 pg 344 says serum osm is high in both and doesn't mention Na specifically. Spent a while double checking for DI, but low serum Na for polydipsia is definitely correct. +2020-01-25T17:40:25Z
If urine concentrates with administration of ADH analog, the kidneys are responsive and the problem is with ADH production in the hypothalamus or release in the post. pituitary.
