When assessing a client at 38-weeks gestation, the practical nurse (PN) determines that she has one set of female twins, who are now 6 years old, a son who is 4 years old, and last year she had a fetal loss at 24-weeks gestation. Which is the correct gravidity and parity for this client?

A. Gravida (G) refers to the total number of pregnancies. This option counts all four pregnancies (twins, son, fetal loss) which is correct. Parity (P) refers to the number of pregnancies that have reached viable gestational age (20 weeks or beyond). Since the fetal loss at 24 weeks is included in the count, the parity is incorrectly stated as 4. B. Gravida (G) counts all four pregnancies, which is accurate. Parity (P) considers only the pregnancies that reached viable gestational age. As there are two children from the twins, one child aged 4 years, and the fetal loss at 24 weeks (which is not considered as viable gestational age), the correct parity is 3. C. Gravida (G) represented as 'S' typically indicates "stillbirths" rather than the total number of pregnancies. It does not provide an accurate representation of all pregnancies, so this is not the correct choice. D. Gravida (G) counts five pregnancies, which doesn't accurately represent the scenario as there have been four pregnancies, not five. Parity (P) as 2 doesn't account for the twins, so it's incorrect.
