Question

When using a tympanic membrane thermometer, how should the speculum probe be positioned with respect to the ear canal to ensure?

1) an appropriate seal is created to prevent the ear canal from being exposed to ambient temperature.
2) that the risk of transmission of micro-organisms is reduced

Answer 1

When using a tympanic membrane thermometer, the speculum probe should be positioned in the ear canal towards the eardrum to create a seal and prevent exposure to ambient temperature. This positioning also reduces the risk of transmission of micro-organisms.

Step-by-step explanation:

When using a tympanic membrane thermometer, the speculum probe should be positioned in the ear canal to create an appropriate seal and prevent exposure to ambient temperature. The speculum probe should be directed towards the eardrum (tympanic membrane) and inserted gently, ensuring a snug fit without applying too much pressure.

This positioning helps create an enclosed space between the speculum probe and the ear canal, preventing temperature changes from the external environment. Additionally, this positioning reduces the risk of transmission of micro-organisms by minimizing contact with the outer areas of the ear canal.
