The nurse determines that the woman who least needs screening for chlamydial infection is a

A. 22-year-old with multiple partners: Individuals under 25 years of age and those with multiple sexual partners are at increased risk for chlamydial infection. Routine screening is strongly recommended to detect asymptomatic infections and prevent complications. B. 35-year-old with a single partner: A woman in a monogamous relationship with no additional risk factors is at lower risk for chlamydial infection. Routine screening in this population is less urgent unless risk factors change or symptoms arise. C. High-risk pregnant woman: Pregnant women at high risk for sexually transmitted infections require screening to prevent adverse maternal and neonatal outcomes, including preterm labor and neonatal conjunctivitis or pneumonia. D. Sexually active 17-year-old: Adolescents under 25 are considered high-risk due to biological susceptibility and behavioral factors. Routine screening is recommended even in the absence of symptoms.
