A nurse is observing an assistive personnel (AP) take a client's tympanic temperature. Which of the following actions should the nurse identify as an indication that the AP understands how to perform the procedure?

A. The AP points the probe posteriorly is incorrect. When using a tympanic thermometer for adults or children older than 3 years, the probe should be directed posteriorly and slightly upwards to align with the ear canal. The posterior direction is correct for adults, but this phrasing is not precise enough for the intended technique. B. The AP pulls the pinna up and back is correct. When taking the temperature of a client older than 3 years using a tympanic thermometer, the pinna (ear) should be pulled up and back to straighten the ear canal and ensure accurate measurement. This action indicates the AP understands proper technique. C. The AP positions the client facing her is incorrect. The client’s position does not directly affect the ability to take a tympanic temperature. The focus should be on positioning the ear and probe, not on facing the nurse. D. The AP inserts the probe with a straight, forward motion is incorrect. The correct motion is straight into the ear canal, not forward, and it is more precise when the probe is inserted gently without forcing it.
