Correct answer: E — Term prelabour rupture of membranes

Rupture of membranes before labour at 37 weeks or later is term prelabour rupture of membranes. Established labour is not present because she has no contractions, and infection is not suggested by the normal temperature and reassuring history. The pearl is that the term diagnosis determines the balance between short expectant management and induction planning.
