Pregnant woman at 38 weeks experiences regular, painful contractions. What phase is she in?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) - Parturition
Explanation:
- At 38 weeks, regular painful contractions indicate the onset of parturition (childbirth).
- Implantation occurs 7 days post-fertilization (early pregnancy).
- Placental formation is completed by the end of the first trimester.
- Lactation begins postpartum (after delivery).
Key Concept:
Parturition is triggered by oxytocin-induced uterine contractions, leading to fetal expulsion. 38 weeks is full-term pregnancy, and contractions signify active labor.
