- G2P2
- G3P2
- G3P3
Show Solution
The Correct Option is A
Solution and Explanation
Clinical pearl: count pregnancies, not babies. The trap in this question is multiple gestation.
Gravida (G) = total number of times a woman has been pregnant. One previous twin pregnancy plus the present one gives G = 2.
Para (P) = number of deliveries past 20 weeks of gestation. The previous twin birth is a single delivery event, so P = 1. Twins do NOT make it P2.
Quick elimination: any option with G3 (options c and d) is wrong because she has only ever been pregnant twice. Between G2P1 and G2P2, the P2 choice wrongly counts each twin as a separate birth, so it is out. That leaves G2P1.
Mnemonic: 'one belly, one bump on the chart' - a multiple pregnancy advances the score by exactly G+1 and P+1.
