Step 1: Understanding the Concept:
The process of parturition (labor) is divided into three distinct stages, each characterized by specific physiological activities in the uterus and abdominal muscles.
Step 2: Detailed Explanation:
Let us evaluate both statements:
- Statement (I): The third stage of labor involves the expulsion of the placenta (fetal membranes). This stage is primarily driven by mild, rhythmic uterine contractions coupled with hematoma formation at the placental attachment site. Active abdominal straining (abdominal press) is minimal or completely absent during this stage. Therefore, claiming that regular abdominal contractions begin in this stage is incorrect. Thus, Statement (I) is false.
- Statement (II): The second stage of labor is the expulsion of the fetus. This stage requires maximum physical effort from the mother. It is characterized by powerful, regular, and active uterine contractions synchronized with strong voluntary abdominal contractions (abdominal press or straining). This straining does not cease; it reaches its peak frequency and intensity to push the fetus through the birth canal. Thus, Statement (II) is false.
Therefore, both Statement (I) and Statement (II) are false.
Step 3: Final Answer:
Both Statement (I) and Statement (II) are false, which corresponds to option (A).
