My father has a fever of 102.3 and is spacey. But he refuses to see a doctor. What should I do?
I'm not sure what you mean by "spacey". If he's delirious I think you should get a doctor to see him, or take him to an emergency room, regardless of his wishes.
However, if it's not so serious, and he just has a virus, then what you should do is:
1. Keep him only lightly covered, not too rugged up.
2. Give him plenty of water - iced is best.
3. Give him acetaminophen/paracetamol (e.g. Tylenol) or aspirin or ibuprofen or another non-steroidal anti-inflammatory drug. These will not just make him feel better - they will reduce his temperature.
Of course if his temperature keeps going up you should treat it as serious.
