64 year old male with type 2 diabetes, heart disease and HB pressure, has been vomiting and diarreah for 2 days. Low grade fever, chills, congested cough and sore throat. I can't get him to go to ER have doctors appointment tomorrow at 3:40pm. He cannot keep anything down. I bought a power-aid type drink with low sugar 5mg and sodium is 240, concerned about kidneys and the sodium being diabetic. Is there anything else I can give him to keep him hydrated?? Any suggestions you have to help me get him through the night.
