All are true about delivery of placenta in third stage of labour, EXCEPT?
**Core Concept**
The delivery of the placenta in the third stage of labor is a critical process that involves the separation of the placenta from the uterus and its expulsion. This process is facilitated by the uterus's ability to contract and reduce blood flow to the placental site, promoting placental separation and delivery.
**Why the Correct Answer is Right**
The correct answer involves the understanding of the physiological process of placental delivery. After delivery of the fetus, uterotonic agents like oxytocin are administered to stimulate uterine contractions, which help to reduce blood flow to the placental site, promoting placental separation. The uterus also undergoes a series of contractions, known as the third stage of labor, to deliver the placenta. This process is crucial to prevent postpartum hemorrhage.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a true statement about placental delivery. However, since the options are not provided, I will continue with a general explanation.
**Option B:** This option is incorrect because it may be a true statement about placental delivery, but it is not the correct answer since it is not an exception.
**Option C:** This option is incorrect because it may be a true statement about placental delivery, but it is not the correct answer since it is not an exception.
**Option D:** This option is incorrect because it is not a true statement about placental delivery. For example, if option D stated that "The placenta is delivered without assistance," this would be incorrect because placental delivery often requires assistance, such as gentle traction on the umbilical cord.
**Clinical Pearl / High-Yield Fact**
One key point to remember is that the administration of uterotonic agents, such as oxytocin, is crucial in the third stage of labor to promote uterine contractions and prevent postpartum hemorrhage. This is because the uterus requires strong contractions to reduce blood flow to the placental site and promote placental separation.
**Correct Answer:**
Since the options are not provided, I will leave the correct answer blank. If you provide the options, I can give a more accurate explanation.
