Final answer:
The GTPAL for the 26-year-old woman who is currently 26 weeks pregnant, and with a history of one miscarriage and one term birth, is 3-1-0-1-1. Her gravidity is 3, indicating three pregnancies, and her parity is 1, signifying one pregnancy that reached term viability.
Step-by-step explanation:
The GTPAL acronym is used in medicine to describe a woman's obstetrical history. It stands for Gravidity, Term births, Preterm births, Abortions, and Living children. The gravidity is the total number of pregnancies a woman has had, while parity refers to the number of pregnancies that have reached viability, regardless of whether the child was born alive or was stillborn.
In this case, the 26-year-old woman's GTPAL is 3-1-0-1-1. This means she has been pregnant three times (Gravidity of 3); she has had one term birth (a three-year-old born at 39 weeks); no preterm births (before 37 weeks); one abortion/miscarriage at 10 weeks (Abortions); and one current living child (Living children). Her gravidity is 3 and her parity is 1, since only one pregnancy has resulted in a birth after 37 weeks.
