Question: 1 / 400

What is the primary function of a rhinoscope?

To perform surgery on the throat

To examine the ear

To assess nasal passages

The primary function of a rhinoscope is to assess nasal passages. A rhinoscope is an instrument specifically designed for the visualization of the inside of the nasal cavity and sinuses. It allows healthcare professionals to examine and diagnose issues such as blockages, abnormal growths, or inflammation in the nasal passages, which can be crucial for identifying conditions like sinusitis or nasal polyps.

In contrast to other options, the rhinoscope is not suitable for surgical procedures on the throat, as indicated in the first choice. The instrument is also not intended for ear examinations or preparations for tracheostomy. Each of these areas has its specialized tools and methods, such as otoscopes for ear examinations or specific surgical instruments for throat surgeries. Thus, the assessment of nasal passages accurately reflects the intended use of a rhinoscope.
