Respect
Maintain consent, privacy, comfort and the appropriate examination setting.
At the viva table
Try answering aloud, then open the suggested answer. Examiner questions vary.
01 / Is this a two-bladed opening mechanism?
No. It is a retraction design rather than a paired opening mechanism.
02 / Why may the two ends differ?
They provide alternative sizes or depths.
03 / Is it a uterine instrument?
Its main role is vaginal-wall retraction for exposure.
04 / Can examination continue after consent is withdrawn?
No. Stop and follow appropriate clinical care and communication.
