Review Elderly Dr.'s visit

I am so disappointed as today my uncle was brought there and he was checked by the nurse who said he was running a very high fever. Now this reading was 99 then 98 respectively. I got a second opinion from a friend who is a dr and he advised that 98 would be most normal so I'm very unsure as to why they would say that his fever was very high. Also his pulse and oxygen checks were abnormal there and when we did it they were okay.
