Hi, I care for my mom who is 80, she has tongue cancer and lung cancer, CHF, COPD and emphysema. She is on a peg tube for a year now. She was diagnosed with diverticulitis and is on 2 antibiotics and has had diarrhea for 3 days. He bp is good at 116\60, but pulse is 97-111, I think she is dehydrated, but not sure how much extra fluid to give her. her meds are Lasix, carvadilol, liprosil, cipro and another anti, I don t know right now. She refuses to go to hospital. any suggestions?
