What is the main distinguishing feature of Graves and Pederson speculums?

• A. The material they are made of
• B. The width of the blades
• C. The length of the handle
• D. The color of the coating

Answer: (B)

The main distinguishing feature of Graves and Pederson speculums is indeed the width of the blades. Graves speculums are typically wider than Pederson speculums, which have narrower blades. This difference in blade width makes each type suited for different clinical situations and patient anatomies.

Graves speculums are often used in gynecological procedures because their design allows for a wider view and easier access to the vaginal canal. In contrast, Pederson speculums are designed to be more comfortable for patients, especially those with narrower vaginas, making them useful in situations where a gentler approach is preferred.

Understanding this difference is crucial for surgical technicians and healthcare professionals in selecting the appropriate speculum for examinations and procedures, ensuring both effectiveness and patient comfort during gynecological evaluations.
