What is the typical duration of a full-term pregnancy?

• A. 32 weeks
• B. 36 weeks
• C. 40 weeks
• D. 42 weeks

Answer: (C)

A full-term pregnancy typically lasts for 40 weeks, beginning from the first day of the last menstrual period (LMP) to the birth of the baby. This duration is divided into three trimesters: the first trimester lasts from weeks 1 to 12, the second from weeks 13 to 26, and the third from weeks 27 to 40. Understanding the 40-week duration is crucial in obstetrics for assessing fetal development and determining the appropriate timing for labor and delivery. It is also significant when evaluating any factors that could lead to preterm (before 37 weeks) or post-term (beyond 42 weeks) deliveries. The medical community has established this timeline based on extensive research and observations regarding fetal growth, maternal health, and outcomes linked with delivery timing. Therefore, the identification of 40 weeks as the duration of a full-term pregnancy is consistent with these established guidelines and clinical practices.
