Which of the following features are correct regarding onset of true labour? 1. Regular uterine contractions 2. Progressive cervical dilation and effacement 3. Presence of show 4. Labour and delivery are synonymous Select the answer using the code given below.
Identifying True Labour Features
This question asks to identify the correct features indicating the onset of true labour. Let's analyze each statement:
- 1. Regular uterine contractions: True labour is characterized by uterine contractions that occur at regular intervals, gradually becoming shorter, stronger, and longer in duration. This is a key indicator.
- 2. Progressive cervical dilation and effacement: Changes in the cervix, specifically progressive dilation (opening) and effacement (thinning), are definitive signs that true labour is occurring and progressing.
- 3. Presence of show: The expulsion of the mucus plug, often tinged with blood (known as "show"), is a common sign that the cervix is beginning to change, indicating the approach or onset of labour.
- 4. Labour and delivery are synonymous: This statement is incorrect. Labour is the entire process of childbirth, including uterine contractions and cervical changes, while delivery refers specifically to the birth of the baby. They are distinct phases, not synonymous.
Conclusion on True Labour Signs
Based on the analysis, statements 1, 2, and 3 accurately describe features associated with the onset of true labour.
Selecting the Correct Option
The option that includes features 1, 2, and 3 is the correct choice. Therefore, the correct answer combines:
- Regular uterine contractions
- Progressive cervical dilation and effacement
- Presence of show
This corresponds to Option A (1, 2 and 3).
