What is the primary function of the otoscope?

The primary function of the otoscope is to examine the ear. This medical instrument is specifically designed to provide a clear view of the ear canal and the tympanic membrane (eardrum). By using an otoscope, healthcare professionals can detect various conditions and diseases affecting the ear, such as infections, blockages, or abnormalities. This visualization is crucial for accurate diagnosis and treatment of ear-related issues.

Other options, while related to different aspects of health care, do not align with the specific purpose of the otoscope. For instance, measuring blood pressure involves other specialized instruments, and visualizing the throat typically requires a different tool known as a laryngoscope. Checking heart sounds is done with a stethoscope, which is specifically designed for listening to heartbeats and lung sounds. Thus, the otoscope’s role is singularly focused on ear examination, making it the correct choice for this question.
