Onset of true labour pains to full dilatation of cervix indicates.

Appeared in: OSSSC Nursing Officer-2021

Explanation

The first stage of labor is defined as the period from the onset of true, regular uterine contractions to the point where the cervix is fully dilated to 10 centimeters.
This stage is the longest part of labor and is itself divided into three phases: latent, active, and transition.
The primary physiological processes during this stage are cervical effacement (thinning) and cervical dilatation (opening), which prepare the birth canal for the passage of the fetus.

Option B: The second stage of labor begins after the cervix is fully dilated and ends with the expulsion of the fetus.
Option C: The third stage of labor begins after the baby has been delivered and ends with the expulsion of the placenta and membranes.
Option D: The fourth stage of labor is the immediate postpartum period, lasting 1-4 hours after the delivery of the placenta, during which the mother's condition is closely monitored.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Stages of Labor as background academic context rather than a clinical decision trigger.
Nurses play a critical role during the first stage of labor by monitoring the mother's vital signs, the frequency and intensity of contractions, and fetal heart rate to ensure the well-being of both.
Pain management is a key nursing intervention during this stage, involving both pharmacological (e.g., epidurals) and non-pharmacological methods (e.g., breathing techniques, position changes).
Recognizing the transition from the latent to the active phase is crucial, as labor progression accelerates, requiring more intensive support and monitoring.

How to Approach the Question

Identify the key events described in the question stem: 'onset of true labour pains' (the start event) and 'full dilatation of cervix' (the end event).
Recall the definitions of the four stages of labor.
Match the start and end events from the question to the definition of each stage.
The first stage of labor is defined as starting with true labor pains and ending with full cervical dilatation.
The second stage starts with full dilatation and ends with the baby's birth.
The third stage starts after the baby's birth and ends with placental delivery.
