Where I work if your not GBS+ they let you go 18hours after membranes rupture before starting antibiotics. They usually start the induction process by 24hours from spontaneous membran rupture although depending on what else is going on in DS irs not always possible and they won't start the drip after about 5-6pm as then your likely to be looking at delivering when there are alot less staff around. They prefer to start 6am ideally (I work in a larger rural hospital) if your under 37weeks they will try and get the pregnancy a little further along before inducing.

Where I work 2hrs active pushing is allowed. That doesn't neccessarily mean from the first push as it can take a little bit to get the hang of it and if the pushing is not what is seen as effective pushing then they won't start the timing straight away. However by 1hr of active pushing you are then reviewed by your Ob or the registrar if you can not see progression. If progression is obvious and you know it wont be much longer then no need to have the lady reviewed. All of this is provided bubs heartrate is reassuring on CTG or doppler.

Question no3 is very difficult to answer as some women experience this well before they are in established labour. If labour is established it really depends on the progression of labour and that it is progressing even if very slowly and how mum is coping.

Question 4 is also difficult to answer. I'll be back to asnwer that as I have to run out.
