A 27-year-old pregnant client presents for her prenatal visit at 10 weeks' gestation. She reports a history of two previous pregnancies. The first pregnancy ended in a miscarriage at 12 weeks. The second pregnancy resulted in the vaginal delivery of twin infants at 35 weeks, both of whom are alive and healthy. Based on this history, which documentation of the client's obstetric history is most accurate using the GTPAL system?

Rationale: A. G3 P0-1-1-2 accurately reflects: Gravida 3, Term 0, Preterm 1, Abortions 1, Living 2. The GTPAL system summarizes a woman’s obstetric history: G (Gravida): Total number of pregnancies (including current pregnancy) → 3 (current + 2 previous). T (Term births): Number of pregnancies carried to ≥37 weeks → 0, as the twin delivery was at 35 weeks. P (Preterm births): Number of pregnancies delivered 20–36 weeks gestation → 1, the twin pregnancy at 35 weeks. A (Abortions/miscarriages): Number of pregnancies ending before 20 weeks → 1, the miscarriage at 12 weeks. L (Living children): Number of living children → 2, the surviving twins. B. G2 P0-2-1-2 – Gravida should be 3 (current pregnancy included), and preterm count is correct but gravidity is off. C. G4 P0-1-1-2 – Gravida is too high. D. G3 P1-0-1-2 – Term births are listed as 1, but there were no term births ≥37 weeks.
