What is the most appropriate measure for a nurse to use in assessing core body temperature when there are suspected problems with thermoregulation?
a. Oral thermometer
b. Rectal thermometer
c. Temporal thermometer scan
d. Tympanic membrane sensor
ANS: B
The most reliable means available for assessing core temperature is a rectal temperature, which is considered the standard of practice. An oral temperature is a common measure but not the most reliable. A temporal thermometer scan has some limitations and is not the standard. The tympanic membrane sensor could be used as a second source for temperature assessment.
