What medical instrument is used to examine the ear canal?

• A. Otoscope
• B. Stethoscope
• C. Endoscope
• D. Ophthalmoscope

Answer: (A)

The otoscope is the correct answer as it is specifically designed for examining the ear canal and the eardrum. In a healthcare setting, an otoscope allows a healthcare provider to visualize the inside of the ear, looking for signs of infection, fluid buildup, or other abnormalities. The instrument features a light source and a magnifying lens, which enables a detailed view of the ear canal structures.

Other instruments mentioned serve different purposes: the stethoscope is used to listen to heartbeats and lung sounds, the endoscope is typically utilized for examining internal organs through natural openings or incisions, and the ophthalmoscope is designed for inspecting the interior of the eye. Each of these instruments has its specialized function, making the otoscope the most appropriate choice for ear examinations.
