Final answer:
The term GTPAL stands for Gravida, Term, Preterm, Abortions, and Living children. If a woman's GTPAL is 0, it means she has never been pregnant.
Step-by-step explanation:
The term GTPAL is used in obstetrics and gynecology to assess a woman's obstetric history. It stands for Gravida, Term, Preterm, Abortions, and Living children. The letter 'G' indicates the number of total pregnancies, 'T' represents the number of full-term pregnancies, 'P' represents the number of preterm pregnancies, 'A' represents the number of pregnancies that ended in abortion, and 'L' represents the number of living children.
In this case, if the woman's GTPAL is 0, it means that she has never been pregnant before.
