Which of the following best describes the number of births after 20 weeks?

The term that best describes the number of births after 20 weeks is "Para." This classification refers to a woman who has given birth to one or more viable offspring, typically defined as those born after 20 weeks of gestation.

Understanding "Para" is essential in the context of obstetrics as it helps healthcare professionals assess a woman's obstetric history and determine any potential risks or considerations for future pregnancies. A woman who is classified as "Para" can provide crucial information about her reproductive health, which is relevant for prenatal care and health planning.

In contrast, "Gravia" is typically associated with the number of pregnancies a woman has had, including both live births and losses, while "Nullipara" refers specifically to a woman who has never given birth to a viable offspring. "Secundipara" denotes a woman who has given birth to two viable offspring. These terms reflect different aspects of obstetric history and are important for understanding a patient's background, but in this instance, "Para" is the most specific descriptor for births occurring after 20 weeks.
