The abbreviation 'r' refers to which site?

Explanation:
The letter r is used to indicate the Rectal site for temperature readings. In nursing documentation, R stands for rectal temperature, which is generally the most accurate core temperature and is used when oral or underarm readings may be unreliable. By contrast, oral readings are typically abbreviated O, axillary readings are abbreviated Ax, and apical pulse refers to listening to the heartbeat at the apex rather than a temperature site.
