Hi there, it's my first week of the 2nd semester of the first year in nursing, and i'm having so much trouble trying to get these two in my head, because in my mind they contra-indictate each other. This is about Sodium and Body Fluid Volume. Ok here we go, i hope you guys can understand what i'm getting at... NA+ (Sodium) the ranges i was taught was 135-145 mEq/L Anything higher is Hypernatremia Anything Lower is Hyponatremia and that there is two types of places where fluid can be at Extracellular Volume (ECF) and Intracellular Volume So lets say the serum sodium is 150 mEq/L (Hypernatremia) so hypernatremia would mean dehydration hyponatremia would be overhydration? how would this relate to Hyper/Hypovolemia then? So would Hypernatremia mean Hypovolemia?
