How would you document a 22-year-old female's obstetric history if she has had 3 pregnancies, 2 live births, and 1 previous abortion?

For documenting a patient's obstetric history, the terms used are gravida, para, and abortus. Gravida refers to the number of total pregnancies a woman has had, including the current one if applicable. Para indicates the number of live births after 20 weeks of gestation, while abortus indicates the number of pregnancies that ended before 20 weeks, typically referring to miscarriages or elective abortions.

In this case, the patient is a 22-year-old female with 3 pregnancies, which means her gravida is 3. Since she has had 2 live births that reached or exceeded 20 weeks of gestation, her para is 2. Finally, she has had 1 previous abortion, which is recorded as 1 on the abortus scale.

Therefore, the correct documentation for her obstetric history is gravida 3, para 2, and abortus 1, capturing the total number of pregnancies, successful live births, and previous abortions accurately.
