spontaneous abortion

The loss of a pregnancy on its own, before the fetus can live outside the uterus, usually before 20 weeks; a miscarriage.

spon-TAY-nee-us uh-BOR-shun noun

What it means

The medical term for a miscarriage. Most happen in the first trimester, often because of chromosome problems in the embryo. Types include threatened (bleeding with a closed cervix), inevitable, incomplete (some tissue remains), complete and missed (the pregnancy has stopped growing but has not passed). "Abortion" here does not mean the pregnancy was ended on purpose.

For the nurse

Count pads and watch for heavy bleeding, fever or foul discharge. Check the Rh status; an Rh-negative client may need Rh immune globulin. Give emotional support: grief is common, and the client should hear that the loss was not caused by something they did.
