A client reports nausea, fatigue, and breast tenderness. Which type of pregnancy sign is this?

Rationale: A. Confirmatory signs provide definitive evidence of pregnancy, such as ultrasound visualization of the fetus or detection of fetal heart tones. B. Probable signs are observed by the examiner and suggest pregnancy, such as a positive pregnancy test or uterine enlargement. C. Positive signs are objective, conclusive evidence of pregnancy, like fetal movement felt by a clinician. D. Presumptive signs are subjective symptoms reported by the client, including nausea, fatigue, and breast tenderness, which suggest pregnancy but are not definitive because they can be caused by other conditions.
