What are the three groups of signs of pregnancy?

• A. Positive, negative, and supportive
• B. Presumptive, probable, and positive
• C. Initial, secondary, and advanced
• D. Physical, emotional, and behavioral

Answer: (B)

The classification of signs of pregnancy into presumptive, probable, and positive is widely accepted in obstetrics. Presumptive signs are those that may suggest pregnancy but can be attributed to other causes; they are subjective experiences reported by the mother, such as amenorrhea (missed periods), nausea, and breast tenderness. Probable signs are those that are more indicative of pregnancy but are not definitive, like a positive pregnancy test or changes examined by a healthcare professional, such as uterine enlargement or the presence of Braxton Hicks contractions. Finally, positive signs are definitive indicators of pregnancy, such as the presence of fetal heartbeat or ultrasound confirmation of a fetus.

This framework provides a comprehensive way to assess pregnancy status, with each category reflecting a different level of certainty regarding whether a woman is pregnant. Understanding these categories helps healthcare providers evaluate and monitor pregnant patients effectively, which is crucial for prenatal care.
