Sexual abuse is a problem of epidemic proportions in the United States. In their practice, pediatric nurse practitioners will likely encounter children who have experienced sexual abuse-both those who have and have not previously been identified as victims. Sexually transmitted infections (STIs) are rare in sexually abused children and adolescents.
