Which statement about the transition phase of labor is true?

• A. It is the last phase of the first stage of labor, and complete cervical dilation ends this phase.
• B. It is the opening phase of the second stage of labor.
• C. It occurs after delivery of the baby.
• D. It is characterized by minimal cervical dilation.

Answer: (A)

The transition phase is the final portion of the first stage of labor, culminating in complete cervical dilation (10 cm). It ends when the cervix is fully dilated, which marks the start of the second stage. This phase typically features very strong, frequent contractions and often intense pressure or urging to push. The second stage begins only after full dilation, so stating that transition is the opening phase of the second stage or that it involves minimal dilation would be inaccurate. It also does not occur after delivery.
