A presumptive sign that would lead the nurse practitioner to suspect pregnancy in an adolescent is:

Rationale: A. Abdominal striae are a probable or later sign of pregnancy and are not useful for early suspicion. B. A positive pregnancy test is a positive sign, confirming the presence of human chorionic gonadotropin (hCG), not merely a presumptive indication. C. Breast tenderness is a presumptive sign of pregnancy because it is based on subjective symptoms reported by the adolescent and may be caused by other conditions as well. D. Goodell’s sign (softening of the cervix) is considered a probable sign of pregnancy, as it is an objective finding but not definitive.
