My mom is sick with cancer and malnutrition and is in the hospital now for blood clots. She has rapidly gone downhill the past couple of days. Yesterday she could no longer sip water from a straw. She is on an iv but I'm sure she would like wetness in her mouth. What do you think of a bubble syringe so I can get water to her? (she is having a hard time speaking the past couple days too and also handing people invisible pills etc.... I think she's withdrawing from her strong nausea pills she's been on.).... also should I try to brush her teeth? And how would I do that? Dental care has always been important to her and everyone feels better with a clean mouth. Thank you for your help!
