A speculum exam involves using a speculum to open the vagina and visualize the interior walls, including the os and whether it is open or closed.

• A. Bimanual exam
• B. External exam (Female)
• C. Wet prep
• D. Speculum exam

Answer: (D)

This question tests how a speculum exam is performed and what it allows you to visualize. A speculum is inserted into the vagina to gently open the vaginal walls, giving direct sight of the vaginal canal and the cervix (the os). This is exactly what the description is describing—using a speculum to open the vagina and inspect the interior, including the cervix and whether the os is open or closed.

This differs from a bimanual exam, which involves palpating internal structures with two hands to assess the uterus, ovaries, and adnexa; an external exam only inspects the external genitalia; and a wet prep involves collecting and examining vaginal discharge under a microscope, not opening the vagina with a speculum.
