—Michelle Hutchinson, Marietta

A: Christine Bolden's twin sons were delivered on April 5 after her blood pressure spiked, according to MLive.com, a website for several Michigan newspapers. Bruce Rossman, spokesman for Helen DeVos Children's Hospital in Grand Rapids, Mich., said the doctors knew it was time to deliver the babies, according to the article.

She was declared brain dead on March 6, according to MLive.com, but was kept on life support for about a month to allow the babies to develop.
