The abbreviation 'ty' refers to which site?

• A. Temporal (forehead)
• B. Tympanic (ear)
• C. Oral (mouth)
• D. Rectal (rectum)

Answer: (B)

Ty stands for tympanic, referring to the ear. A tympanic thermometer measures infrared heat from the eardrum through the ear canal, giving a quick, noninvasive temperature reading. This site is distinct from the temporal (forehead) site, the oral (mouth) site, and the rectal (rectum) site, each of which uses different methods and locations for measurement. For accuracy, ensure proper placement and note factors that can affect the reading, like earwax, recent bathing, or crying.
