My Husband Is Getting Futon Radiation On The Right Side

My husband is getting futon radiation on the right side of his brain, 8 treatments so far. He had the tumor removed and it was metastiside from the cancer he has had right lung. His sleep has been 4 or 5 hours at best. He woke up at 3 am agitated and with a slight fever. He is calmer now and has 2 Advil with water. He is extremely tired. He broke his right femur and is getting therapy for that too. Should I take him in to the hospital , he is taking a nap in his wheel chair. He is taking steroids and was just taken off anti seizure medicine about 1 week ago. The tumor was recessed successfully, the radiation is to try and keep anything from coming back. He has been doing chemo for 3 years for the lung.
