Final answer:
The prolonged latent phase for a multipara is 6 hours, and for a nullipara is 12 hours. Multiparas' average cervical dilatation is 1.5 cm/hr in the active phase, and nulliparas' average cervical dilatation is 1 cm/hr in the active phase.
Step-by-step explanation:
The prolonged latent phase for a multipara is 6 hours, and for a nullipara is 12 hours. Multiparas' average cervical dilatation is 1.5 cm/hr in the active phase, and nulliparas' average cervical dilatation is 1 cm/hr in the active phase. So the correct answer is option B) 6 hours, 12 hours, 1.5 cm/hr, 1 cm/hr.
