re: Preeclampsia - what am I in for?

Anything from bed rest to them walking in and saying "Congrats, you are going to be a Dad in 20 minutes because we are inducing labor."

It all depends on a combination of how the mom's system is handling the stress and how the baby is taking it. They are going to be monitoring her labs and urine output for a variety of factors as well as ultrasounding the baby to check on it.

Good news is that, even though they still don't know what causes the condition, they have a pretty good handle on how to deal with it.

I am assuming you are at a reputable Woman's Hospital or other decent facility with a full OB Department? If not, get to one.
