A nurse is assessing a client’s body temperature using a temporal artery thermometer. How should the nurse use the temporal artery thermometer?
A.
Insert the thermometer into the rectum for accurate measurement.
B.
Place the thermometer in the client’s axilla and secure with a towel.
C.
Swipe the thermometer gently across the client’s forehead.
D.
Hold the thermometer under the client’s tongue for 30 seconds.
The correct answer and Explanation is :
The correct answer is C. Swipe the thermometer gently across the client’s forehead.
A temporal artery thermometer is a non-invasive device that measures body temperature by scanning the temporal artery, which is located on the forehead. Here’s how to properly use it:
- Preparation: Ensure the thermometer is clean and functional. If necessary, clean the sensor lens before use.
- Placement: Position the thermometer on the center of the client’s forehead.
- Swiping Technique: Gently press the thermometer against the skin and swipe it across the forehead, moving laterally toward the hairline. Some models may also require you to scan down the side of the neck, just behind the ear. The thermometer detects the heat emitted from the skin over the temporal artery, providing an accurate reading.
- Accuracy: Temporal artery thermometers provide results quickly, typically within a few seconds, and are considered to be as accurate as rectal temperatures, which are a gold standard for core body temperature.
Rationale:
- Non-invasive and comfortable: Temporal artery thermometers are designed for quick, easy, and non-invasive temperature assessment. They are ideal for clients of all ages, particularly children and elderly individuals, because they don’t cause discomfort.
- Axillary and Oral Measurements: Using the thermometer in the axilla (armpit) or under the tongue, as suggested by other options (B and D), would not be appropriate for this type of thermometer. Those methods are used for traditional mercury or digital thermometers.
- Rectal Method (A): While rectal temperature is accurate, it is invasive and unnecessary with a temporal artery thermometer, which is designed specifically for forehead scanning.
In conclusion, swiping the thermometer gently across the forehead provides a reliable and quick temperature reading, making this method an efficient option in clinical settings.
