Advanced Health Assessment Practice Exam

How should an adult’s external auditory canal be positioned for optimal otoscopic examination?

1. Straight down and forward

2. Out, up, and back

3. Inward and downward

4. Straight across

The correct answer is: Out, up, and back

For an optimal otoscopic examination of an adult’s external auditory canal, the correct positioning is to move the ear out, up, and back. This maneuver straightens the canal, providing a clearer view of the tympanic membrane and the structures of the ear. In adults, the ear canal is typically angled, requiring this specific positioning to ensure that the otoscope can be inserted without obstruction. When the ear is pulled out, it allows the canal to become more aligned and straightened, minimizing any curves that could obstruct the view. This positioning also helps prevent discomfort to the patient and makes it easier for the clinician to visualize any potential issues, such as inflammation or perforation of the tympanic membrane. Other options do not provide the proper alignment needed for an effective examination. For instance, positioning the ear straight down and forward, inward and downward, or straight across could result in an obstructed view or not allow the clinician to adequately assess the auditory structures. Thus, the technique of moving the ear out, up, and back is essential for thorough and effective otoscopic evaluation in adults.
