Explanation

The first stage of labor is correctly defined as the period starting from the onset of true, regular, and painful uterine contractions and concluding with the full dilatation of the cervix to 10 cm.
This stage is the longest part of labor and is dedicated to preparing the birth canal for the baby's passage.
It is subdivided into a latent phase, where cervical changes are slow, and an active phase, characterized by more rapid and progressive cervical dilatation.

Option B: The third stage of labor begins after the baby is born and ends with the delivery of the placenta and membranes.
Option C: The second stage of labor begins only after the cervix is fully dilated (10 cm) and ends with the birth of the baby.
Option D: The fourth stage of labor is the immediate postpartum period, typically the first 1 to 4 hours after the delivery of the placenta, where the mother is closely monitored for complications like hemorrhage.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain The question tests the knowledge of the definitions of the different stages of labor as background academic context rather than a clinical decision trigger.
Accurately identifying the stage of labor is a critical nursing skill. It dictates the plan of care, including the frequency of maternal and fetal monitoring, pain management strategies, and readiness for delivery.
During the first stage, nurses monitor contraction patterns, fetal heart rate, and cervical progress using a partograph to ensure labor is progressing safely and to detect any signs of fetal distress or dystocia (abnormal labor).
What if? A woman in the active phase of the first stage (e.g., 7 cm dilated) feels a strong, premature urge to push. The nurse's first action should be to encourage panting or blowing breaths and perform a vaginal exam to check for full dilatation. Pushing on an incompletely dilated cervix can cause cervical edema, exhaustion, and potential injury.

How to Approach the Question

This is a factual recall question that tests the definition of a fundamental concept in obstetrics.
Identify the key phrases in the question: "onset of true labour pains" (the start point) and "full dilatation of cervix" (the end point).
Systematically recall the definition of each stage of labor provided in the options.
Compare the period described in the question with the definitions of the four stages.
The first stage of labor is defined as starting with true labor pains and ending with full cervical dilatation, which directly matches the question.
Eliminate the other options as their definitions do not match the timeframe given in the question stem.
