What is the primary use of a vaginal speculum?

The primary use of a vaginal speculum is to open the vagina for examination. This instrument is designed to provide visibility and access to the vaginal canal and cervix, allowing healthcare providers to perform various examinations, such as a Pap smear, pelvic examination, or other gynecological assessments. By gently spreading the walls of the vagina, the speculum holds the vaginal walls open, which facilitates a thorough evaluation of the reproductive organs.

In contrast, performing a hysterectomy involves surgical techniques and instruments far more invasive than a simple examination tool like the speculum. Collecting urine samples typically requires different tools, such as a urinary catheter or a simple cup, rather than a speculum. Administering medication usually involves other methods, such as injections or oral routes, rather than using a speculum, which is not designed for medication delivery. Thus, option B accurately describes the primary and intended function of a vaginal speculum in clinical practice.
