So that should be fixed to always make it possible to complete the quest.
Korum suggested putting a bandage drop somewhere down there, so you can raise her with that.
I think it'd be more fun to have a dialogue option with her with several options:
Bandage her wounds: {requires healing kit or bandages}
Heal her wounds: {requires a prepared healing spell or lay on hands spell, or healing potion}
Revive her: {requires a raise dead scroll, resurrection scroll or prepared spell of either}
Carry her: {Can always be chosen, a fall back if you can't heal her at all, and gives less exp than the other options}
