Final answer:
The nurse should emphasize the need for annual screening for chlamydia in all sexually active women younger than 25 years of age.
Step-by-step explanation:
The nurse giving a presentation about chlamydia should emphasize the need for annual screening for this infection in all sexually active women younger than 25 years of age.
Since chlamydia is often asymptomatic and can cause significant complications such as pelvic inflammatory disease (PID), ectopic pregnancy, and infertility, routine screening is essential. It is especially relevant for this age group because they represent a high incidence of chlamydia infections. The recommendation also applies to older women with risk factors like new or multiple sexual partners or a sexual partner with an STI, in addition to pregnant women who are screened during prenatal care.
