Certified EkG technician (CET) Practice Exam

What method is considered most accurate for an EKG technician to measure a patient’s body temperature?

1. Rectal

2. Aural

3. Temporal

4. Oral

The correct answer is: Temporal

The temporal method is widely recognized for its accuracy in measuring a patient’s body temperature. This technique involves using a forehead thermometer that scans the temporal artery, which is located just beneath the skin. It provides a quick reading and is less invasive than rectal measurement. Temporal thermometers are also convenient for use in clinical settings, as they can provide results in just a few seconds and are suitable for patients of all ages. Compared to other methods, the temporal measurement can also account for external variables such as ambient temperature, offering a more reliable indication of core body temperature in situations where immediate results are essential. Additionally, this method is particularly useful for patients who may find other methods uncomfortable or unfeasible, thus enhancing patient compliance. While rectal temperature is often considered the gold standard in terms of accuracy, it is more invasive and can be uncomfortable, which may not make it the preferred choice in many scenarios. Aural measurements can be affected by external factors, like earwax, and oral readings may not always reflect core temperature accurately, especially if patients have difficulty with the measurement or have recently consumed hot or cold substances. Hence, the temporal method strikes a balance between accuracy, efficiency, and patient comfort.
