Final answer:
The nurse would record G3P1.
Step-by-step explanation:
The nurse would record G3P1.
The notation G3P1 stands for gravida 3, para 1. Gravida refers to the number of times a woman has been pregnant, including the current one. Para refers to the number of pregnancies that have reached viability (20 weeks or more), regardless of the outcome. In this case, the client has been pregnant three times, with one living child (para 1) and one abortion. Therefore, the nurse would record G3P1.
