Which type of vulvovaginitis can occur due to hormonal changes such as menopause or aging?

Choice A rationale:

Bacterial vaginosis (BV) is primarily associated with endogenous transmission, meaning it is caused by an overgrowth of normally occurring vaginal bacteria rather than being directly transmitted from another individual.

Choice B rationale:

While sexual transmission can play a role in the development of BV, it is not the primary mode of transmission for this condition.

Choice C rationale:

Vector transmission involves the transfer of pathogens by a vector such as a mosquito or tick and is not relevant to bacterial vaginosis.

Choice D rationale:

Contact transmission typically involves direct physical contact with an infected person or contaminated object, which is not the main mode of transmission for BV.

Choice A rationale:

Anaerobic bacteria typically cause a foul-smelling discharge, which doesn't match the described symptoms.

Choice B rationale:

Fungal infections result in a thick, white, cottage cheese-like discharge, different from the green-yellow frothy discharge mentioned.

Choice C rationale:

Protozoa, specifically Trichomonas vaginalis, cause green-yellow frothy discharge with a foul odor, closely resembling the client's symptoms.

Choice D rationale:

Low estrogen levels would not cause this specific presentation; they're more associated with vaginal dryness and thinning of vaginal walls.
