A 32-year-old multipara (G3P2) at term is admitted in spontaneous labor. Initial cervical examination: 3 cm dilation, 70% effacement, vertex at −1 station. Contractions are 2 in 10 minutes, mild intensity. A partograph is plotted at admission (0 hours). At 6 hours, cervical dilation is 4 cm with contractions now 4 in 10 minutes, moderate intensity. The 6-hour point is plotted and lies 2 cm to the right of the alert line. What does this finding indicate, and what is the most appropriate management?

Question

Accepted Answer

B. The patient is progressing slower than expected but has not yet reached the action line; continue augmentation and reassess. ## Partograph Interpretation: Alert Line vs. Action Line

**Key Point:** A cervical dilation point that falls between the alert line and the action line indicates slow progress requiring continued augmentation and close monitoring. The action line is 4 cm to the right of the alert line; crossing it mandates operative delivery.

### Partograph Zones and Clinical Significance

| Zone | Position | Clinical Status | Management |
|------|----------|-----------------|-------------|
| **Normal** | Left of alert line | Normal labor progress | Expectant management |
| **Slow Progress** | Between alert and action line | Prolonged labor; inadequate contractions | Augmentation; reassess |
| **Arrest** | On or right of action line | Arrest of labor; likely CPD or obstruction | Cesarean section |

**High-Yield:** The action line is positioned 4 cm to the right of the alert line. A point 2 cm right of the alert line is still in the "slow progress" zone, not yet in the "arrest" zone.

### Why This Patient Has NOT Reached the Action Line

1. The 6-hour dilation point is 2 cm right of alert line, not 4 cm (action line position)
2. Contractions have improved from 2 to 4 per 10 minutes (trend toward adequacy)
3. Station has not changed (−1), but cervical dilation is progressing, albeit slowly
4. No signs of cephalopelvic disproportion or obstructed labor are documented

**Clinical Pearl:** Multiparity is associated with faster labor progress than primigravidity. Even in a multipara, a point between alert and action lines warrants augmentation and reassessment rather than immediate surgery. The partograph's design is to prevent both unnecessary cesarean sections and prolonged obstructed labor.

**Mnemonic:** **2 cm RIGHT of ALERT = SLOW; 4 cm RIGHT of ALERT = STOP (cesarean).** The action line is the surgical threshold.

Answer

A. The patient has normal labor progress and requires no intervention

Answer

C. The patient has obstructed labor and should undergo emergency cesarean section without further delay

Answer

D. The patient has crossed the action line and requires immediate cesarean section for arrest of labor
