What is a nullipara?

• A. A woman who has never given birth beyond twenty weeks
• B. A woman who has never been pregnant
• C. A woman who has given birth once
• D. A woman who has had two pregnancies

Answer: (D)

Nulliparity means a woman has never delivered a baby beyond a viable gestational age. In obstetrics, gravidity counts all pregnancies, while parity counts pregnancies carried to viability (usually 20 weeks or more). A primipara has delivered once at or beyond 20 weeks, and a multipara has delivered two or more times. So simply having two pregnancies doesn’t define nulliparity unless neither pregnancy reached viability. The description that best defines nulliparity is never having given birth beyond twenty weeks.
