Final Answer:
The given statement "When using a tympanic thermometer - Pull the ear up and back for an adult or down and back for a child below 3 yrs old to straighten the ear canal" is b) False.
Step-by-step explanation:
Using a tympanic thermometer requires pulling the ear up and back for an adult or down and back for a child below 3 years old is incorrect. The correct technique for both adults and children is to gently pull the earlobe back and slightly upward for accurate readings. Pulling the ear up and back for adults or down and back for children may cause discomfort and potentially lead to inaccurate temperature measurements.
The tympanic membrane, commonly known as the eardrum, is located at the end of the ear canal. To obtain an accurate reading, the infrared sensor of the tympanic thermometer must be aligned with the tympanic membrane. Gently pulling the earlobe back and slightly upward helps to straighten the ear canal, allowing the sensor to accurately measure the infrared radiation emitted by the tympanic membrane.
It is crucial to follow the correct procedure to ensure precision in temperature readings, especially in healthcare settings where accurate measurements contribute to proper diagnosis and treatment. Incorrect technique not only compromises the accuracy of temperature readings but may also cause discomfort or potential harm to the individual, particularly in the case of young children.
Health professionals and caregivers should be trained on the appropriate use of tympanic thermometers to maintain accuracy and patient comfort. So, Option b is correct.
