OBG · Labor: arrest disorders

Sample item

During active labor, cervical dilatation remains unchanged despite adequate contractions over the required observation period. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Active-phase arrest

Active-phase arrest is failure of cervical dilatation to progress during established active labor despite adequate uterine activity over a defined period. Management considers fetal status, contraction adequacy, and cephalopelvic factors.

Option by option

  • A. Precipitous labor

    Precipitous labor is unusually rapid delivery.

  • B. Placenta accreta

    Placenta accreta is abnormal placental adherence.

  • C. Shoulder dystocia

    Shoulder dystocia occurs after delivery of the head.

  • D. Active-phase arrest (correct)

    Correct. No dilatation progress in active labor defines an arrest disorder.
