Final answer:
The most accurate documentation would be contractions lasting around 1 minute with a soft fundus between.
Step-by-step explanation:
The most accurate documentation would be option A: Contractions lasting around 1 minute with a soft fundus between.
During labor, contractions typically occur every 1.5-2 minutes and last for a full minute.
The fundus, which is the top part of the uterus, is difficult to indent with the fingertips during the contraction.
However, between contractions, the fundus should be soft.
Option B is incorrect because a hard fundus between contractions is not consistent with normal labor.
Option C is incorrect because contractions lasting 2 minutes would be longer than normal, and option D is incorrect because contractions lasting 30 seconds would be shorter than normal.
