Which of the following is a risk factor for septic abortion?

The use of an intrauterine device (IUD) is recognized as a risk factor for septic abortion. This is because an IUD can potentially introduce bacteria into the uterine cavity, leading to infection. If a pregnancy occurs with an IUD in place, there is an increased risk of complications, including septic abortion. The presence of the IUD during an abortion procedure can also increase the likelihood of contamination, further heightening the risk of sepsis.

Illustrating the context surrounding the incorrect options can provide better understanding. Prior cesarean delivery is primarily a risk factor for complications related to future pregnancies, such as uterine rupture or placenta issues, but it is not directly linked to an increased risk of septic abortion. Similarly, a history of eclampsia relates to severe hypertension and neurological complications during pregnancy, but it does not inherently increase the risk of septic abortion. Lack of prenatal care can contribute to a range of pregnancy-related issues, but it is more associated with overall maternal and fetal health rather than specifically increasing the risk of septic abortion.
