One of my friends had pre-eclampsia. This information below is from a website called Tommy's. (I think if I knew that my current partner was in this situation I might feel rather on edge and be unsure how to deal with juggling responsibilities.)

Severe pre-eclampsia
If mild pre-eclampsia progresses to more severe pre-eclampsia, you’ll need to be admitted to hospital. That way you’re in the right place if you need treatment and/or if the baby needs to be delivered.
Before birth
If necessary you’ll be given medication to control your blood pressure. You’ll be cared for by an experienced midwife, senior obstetrician and anaesthetist.
You may have the following tests:
Regular blood pressure checks: If you’re stable and are showing no symptoms, this will most likely be every four hours. However, if the pre-eclampsia is severe, this may be as often as every 15 minutes, and after you have stabilised, every half hour.
Daily urine tests to measure the level of protein present.
Blood tests: These will be taken to check your blood count, clotting, liver and kidney function.
Ultrasound scans: These scans will help your medical team to measure your baby’s growth and wellbeing.
Fetal heart monitoring: If pre-eclampsia is severe, you may have twice-weekly monitoring. While in labour, your baby’s heart rate will need to be monitored continuously.
Giving birth
If you develop pre-eclampsia in late pregnancy, it is common practice to induce the baby. The baby is usually delivered if the doctors can’t control your blood pressure, if the liver, kidney or clotting blood tests become very abnormal, or if the baby becomes distressed.
Most women with severe pre-eclampsia will need to be delivered within two weeks of being diagnosed of it.
The risk to your baby is small if he or she is born just a few weeks early. Pre-eclampsia is the cause of around 15 percent of induced premature births.
However, if you are less than 34 weeks, the decision between delivery or other treatment will depend on the severity of the pre-eclampsia (and its risks to you and the baby) versus the risk of being born prematurely to your baby.
