What is the primary function of an otoscope?

• A. To examine the throat
• B. To measure blood pressure
• C. To examine the ear canal and eardrum
• D. To check heart sounds

Answer: (C)

The primary function of an otoscope is to examine the ear canal and eardrum. This handheld device consists of a light source and a magnifying lens that allows healthcare professionals, including Hospital Corpsmen, to visualize the structures of the ear for assessment and diagnosis. It is particularly useful for identifying any abnormalities, such as infections, blockages, or perforations in the tympanic membrane (eardrum). Proper use of an otoscope can help in diagnosing conditions that may affect hearing or lead to further complications if left untreated. The other options involve functions that are either unrelated to the ear or pertain to different areas of the body. For instance, examining the throat is typically done using a tongue depressor and not an otoscope. Measuring blood pressure is conducted with a sphygmomanometer, and checking heart sounds requires a stethoscope. Each of these tools serves a specific purpose in healthcare, distinct from the otoscope's role in examining the auditory system.
