pitting edema w/ tight shiny skin, JVD, moist crackles, cough, headache, agitation,
confusion, labs
Edema Image - ANSWER -
Hypovolemia - ANSWER - Dehydration
Hypovolemia Etiology - ANSWER - loss of water and Na+ (vomiting, diarrhea,
diaphoresis, diuretics), decreased intake (NPO, anorexia, dysphagia)
