2
Q

HYPERnatremia Signs and Symptoms
A
dry mouth, thirsty (already dehydrated by the time their thirsty), swollen tongue (extreme)
neuro changes
5
Q
Treatment for HYPERnatremia

don’t restrict fluids, dilute pt with fluids (makes Na decrease), daily weights, I&O, lab work
if you’ve got a Na problem, you’ve got a fluid problem
6
Q

A
too much water, not enough Na
7
Q
