A patient tells the nurse that she knows all about sexually transmitted infections and proceeds to make the following statements. Which one is the only correct statement that the client makes?

Choice A rationale Asymptomatic sexually transmitted infections (STIs), such as chlamydia, gonorrhea, or human papillomavirus (HPV), are highly transmissible. Pathogens are present and replicating even without overt clinical signs or symptoms in the host. Transmission relies on the exchange of body fluids or skin-to-skin contact where the infectious agent is present, making asymptomatic individuals significant in STI spread. Choice B rationale It is possible to have a sexually transmitted infection without any noticeable signs or symptoms, known as an asymptomatic infection. Many common STIs, including Chlamydia trachomatis and Neisseria gonorrhoeae, frequently cause subclinical or mild infections that go unrecognized. This is due to the host's immune response or the pathogen's characteristics, allowing the infection to persist without acute inflammation. Choice C rationale Biologically, women generally face a higher risk for acquiring many STIs than men. The larger mucosal surface area of the cervix and vagina exposed during intercourse, along with the presence of columnar epithelial cells in the endocervix that are highly susceptible to pathogens like Chlamydia, contributes to this increased biological vulnerability. Choice D rationale Sexually transmitted infections (STIs) are not passed only during intercourse (vaginal or anal). Many can also be transmitted via oral-genital contact (e.g., herpes, syphilis), skin-to-skin contact in the genital area (e.g., HPV, herpes), or sharing of sex toys. Non-sexual transmission (e.g., mother-to-child during birth or blood transfusions) can also occur.
