Final answer:
The pt's Gravidity is 4 and her Parity is 3.
Step-by-step explanation:
To record the pt's Gravidity & Parity using the GTPAL notation, we need to understand the meaning of each letter. G stands for Gravidity, which refers to the total number of times the woman has been pregnant, including the current pregnancy. T stands for Term births, which are pregnancies that have reached 37 or more weeks of gestation. P stands for Preterm births, which are pregnancies that have reached 20 to 36+6 weeks of gestation. A stands for Abortions or miscarriages, which are pregnancies that ended before 20 weeks of gestation. And L stands for Living children. Based on the given information, the pt's Gravidity is 4 (1 single gestation + 1 set of twins + 1 current pregnancy), and her Parity is 3 (1 term birth + 1 preterm birth + 1 living child).
