If your blood pressure doesn't settle or respond to medication, an induction can be done but a few things.

If your cervix is even slightly open they can break the waters instead of an artificial oxytocin drip (syntocinon) straight up. It gives your labour more of a chance to let the hormones work more naturally and has less chance of increasing the risk of fetal distress and other effects for you and your baby. If they use a drip, they can start the drip really low, around 20, and go up in increments until you are labouring at what they want you to. At any time, you can ask for the drip to be turned down or off, I have done this several times in births and the labours have continued normally without it, right until birth. Ideally you wont need synto, it's not nice, but at least know your rights and options with it should it get to that. They may entice you to have an epidural to help with your blood pressure, yes this will lower blood pressure but in effect, oxygen for your baby. This, especially combined with syntocinon, can increase fetal distress especially when pushing leading to assisted delivery. Epidurals also lead to ineffective pushing so you can see how one little thing can mean many in the bigger picture. So aim for the least, if you need more, then you at least know that there are things you can say no to or negotiate.
