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?

Choice A Reason: Inserting the probe with a straight, forward motion is not correct because the ear canal is curved, and this technique could lead to inaccurate readings or discomfort. Choice B Reason: The AP positions the client facing her. The position of the client's face is not relevant to taking a tympanic temperature. The client can face any direction during the procedure. Choice C Reason: Pulling the pinna up and back straightens the ear canal in adults, allowing for a more accurate reading when taking a tympanic temperature. Choice D Reason: Pointing the probe posteriorly is incorrect as the probe should be pointed towards the tympanic membrane, which usually requires slight angling to align with the ear canal.
