Which term refers to the number of live births?

• A. Gravidity
• B. Parity
• C. Gestational Sac
• D. Empty Amnion Sign

Answer: (B)

Think in terms of how obstetric history is described: how many times a patient has carried pregnancies to a viable point. Parity is the term used for the number of pregnancies that have reached a viable gestational age and were delivered. That’s why it’s the best fit for “the number of live births.” For example, a patient who has had two full-term deliveries and one miscarriage before viability would be described as parity two (two pregnancies reached viability with live births), while gravidity would count all pregnancies regardless of outcome. The other terms are not about counting births: the gestational sac is an early ultrasound finding, and the empty amnion sign is a specific ultrasound sign not related to birth counts.
