When measuring temperature, what can affect the accuracy if the device is not placed properly?

• A. Change in skin color
• B. Improper location
• C. Patients' mood
• D. Environmental temperature

Answer: (B)

The accuracy of a temperature measurement is critically dependent on the proper placement of the measuring device. If the device is not positioned appropriately, it may not accurately reflect the body temperature. For example, if an oral thermometer is not placed under the tongue correctly, it may yield a lower temperature reading because it could be measuring the temperature of the air instead of the core body temperature. Similarly, if a tympanic thermometer is not aimed correctly at the eardrum, it may miss capturing the accurate internal temperature. Therefore, ensuring the thermometer is placed in the correct anatomical location is essential for obtaining reliable and valid temperature readings. Factors such as a change in skin color, a patient's mood, or environmental temperature may influence overall comfort or perception but do not directly impact the measurement accuracy as significantly as improper location.
