Which of the following statements regarding different temperature sites is correct?

• A. Rectal temperatures are the least accurate.
• B. Rectal thermometers are always glass thermometers.
• C. Oral thermometers can be used on unconscious residents.
• D. Tympanic thermometers take a faster temperature reading than oral thermometers.

Answer: (D)

Measuring temperature at different sites changes how fast you get a reading and how reliable it is in practice. Tympanic thermometers read through the ear and are built to give a result in seconds, which makes them faster than oral thermometers that require the patient to cooperate and to wait for the reading to stabilize. That speed is why the statement about tympanic readings being faster than oral readings is the best fit. Rectal temperatures are not the least accurate; they often closely reflect core temperature, especially in infants, and are considered quite reliable in many clinical situations. Rectal thermometers are not always glass; today many are digital or disposable. Oral thermometers should not be used on unconscious residents due to the risk of choking or aspiration, making that statement incorrect. Tympanic readings are fast, but they can be affected by earwax, improper placement, or ear infections, which is why technique and context matter. In short, the fastest reading among common sites comes from tympanic measurements, which is why that option stands out as correct.
