Acute Hypernatremia

Evelyn is a 82-year-old female presenting with confusion and lethargy found by family after several days of illness. My daughter came to check on me today and found me in bed, very confused and not making much sense. She says I've been sick for about five days now. It started with terrible diarrhea — loose, watery stools many times a day, maybe 8-10 times on the worst days. Your task is to take a focused history from this patient.
