The school nurse is developing a curriculum for a junior human sexuality class. In order to provide the most up-to-date information, the nurse should be aware that which is the single most effective primary prevention strategy for preventing sexually transmitted infections (STIs) ?

A) A vaccine to prevent HPV infection
B) HIV screening
C) Abstinence
D) The male condom

The single most effective (100%) way to prevent sexually transmitted infections is abstinence. When used correctly, the male condom is an effective method for preventing sexually transmitted infections as well as being a very highly effective contraceptive agent. A significant primary prevention strategy is the recent introduction of a vaccine used to prevent cervical cancer and genital warts caused by HPV. One of two FDA-approved vaccines should be routinely administered to 11- and 12-year-old girls and can be given up to the age of 26. HIV screening is recommended for all sexually active teens by the Centers for Disease Control and Prevention. Screening for existing infection is a secondary prevention strategy. By educating teens towards behavior change related to high-risk behaviors, nurses may be able to reduce the risk for contracting sexually transmitted infections.
