Which instrument is double-ended with rounded ends, used to dilate passages?

• A. Vaginal Speculum
• B. Hank Dilators
• C. Nasal Speculum
• D. Arthoscope

Answer: (B)

Dilators are instruments used to widen a body passage or opening gradually and with minimal trauma. Hank dilators are designed as double-ended tools with rounded tips, so you can apply gentle, progressive dilation using opposite ends of the same instrument or switch sizes without changing tools. The rounded ends help reduce tissue injury while expanding the opening, making them versatile for dilating various passages such as a vaginal canal, a cervical opening, or other narrow tracts as needed. The other instruments serve different purposes: a vaginal speculum is built to hold the walls of the vagina apart for visualization, using blades rather than rounded tips; a nasal speculum widens the nostril area with blades for inspection, not a dilating tool; an arthroscope is a camera used inside joints to visualize internal structures, not for dilation.
