Do you subtract a degree from rectal temperature?

Answer 1

No. You only add a degree when taking a axial (under the arm) temp. This is because the axial temp is taken externally, so it only gives a close approximation of the body's internal temperature. Since oral temps are taken from inside the mouth, they give you the accurate internal body temperature without having to add anything.

Answer 2

Rectal temperature is higher than axillary and oral temperature.

Answer 3

A rectal temperature is considered the most reliable. You do not need to add or subtract from a rectal temp.

Answer 4

no rectal temp is 99.6 you subtract
