I've seen rectal temp probes placed during trauma to monitor temps over a period of time, and (at least here) they are used on peds under 18 months because its more accurate than axilla and its hard to tell a baby to place anything under the tongue. I've never seen it used in other situations but every hospital probably has their own policy on the matter. Yes, its pretty invasive but it gets the job done.
Its most accurate because it will read your "core" temperature instead of a peripheral temp. Maybe it was used because you just drank a hot coffee or a cold cup of water? These things will drastically alter the reading obtained from your mouth.

I had a fever earlier this week and when I went to get it checked out the nurse took my temperature in my butt!
I don't think I've ever had it that way but she said it was the most accurate.
It didn't really hurt but when she put it in I felt like I had to go poo really badly. And when she removed it right away she grabbed a wipe and wiped my butt once. Why do you think she wiped it?? I was too embarrassed to ask
