Final answer:
The woman's gravidity and parity using the GTPAL system is 4-1-2-0-3.
Step-by-step explanation:
Using the GTPAL system, the gravidity refers to the total number of pregnancies a woman has had, including the current one. In this case, the woman is pregnant for the fourth time, so her gravidity is 4.
The parity refers to the outcome of those pregnancies. The GTPAL system breaks down parity into specific categories:
- G: The number of full-term pregnancies (at least 37 weeks) resulting in a live birth. In this case, the woman has had one full-term pregnancy resulting in a live birth.
- T: The number of preterm pregnancies (between 20 and 36.6 weeks) resulting in a live birth. In this case, the woman has had two preterm pregnancies resulting in a live birth (twins born at 34 weeks and another child born at 35 weeks).
- P: The number of pregnancies ending before 20 weeks. In this case, the woman has had no pregnancies ending before 20 weeks.
- A: The number of pregnancies ending in abortion (either spontaneous or induced). In this case, the woman has had no pregnancies ending in abortion.
- L: The number of living children. In this case, the woman has three living children.
Based on the information provided, the woman's gravidity and parity using the GTPAL system is 4-1-2-0-3.
