Sexual Assault Nurse Examiner (SANE) A Practice Exam

The presence of T. vaginalis, C. albicans, and bacterial vaginosis as the most common causes aligns directly with the nature of vaginal infections. T. vaginalis is a protozoan parasite responsible for trichomoniasis, an infection characterized by vaginal discharge and irritation. C. albicans, a yeast organism, is the primary cause of candidiasis, often leading to itching, burning, and uncomfortable discharge. Bacterial vaginosis, on the other hand, arises from an imbalance in the natural bacterial flora of the vagina, also resulting in unusual discharge and odor. These pathogens all impact the vaginal environment, creating conditions that lead to symptoms associated with vaginal infections rather than the other options presented. While they could potentially contribute to more systemic or different types of infections, their direct association and prevalence in causing vaginal infections solidifies this choice.
