Sign of separation of Placenta | Crack AIIMS, AIPG NOV 2016 MCQs


Which one of the following is not a sign of separation of placenta? 

A. Fundus of the uterus rises to the umbilicus 
B. The uterus is well contracted and retracted 
C. The cord “lengthens” when you press the uterus down, but recedes on release 
D. Excessive vaginal bleeding

Answer. C (The cord “lengthens”when you press the uterus down, but recedes on release)
The 3rd stage of labor comprises the phase of placental separation and its expulsion.
Signs of placental separation
1. The uterus becomes globular and firmer and ballotable.
2. There is often a sudden gush of blood.
3. The uterus rises in the abdomen because the placenta, having separated, passes down into the lower uterine segment and vagina, where its bulk pushes the uterus upward.

4. The umbilical cord protrudes further out of the vagina, indicating that the placenta has descended.
5. Permanent lengthening of the cord stabilized. This can be elicited by pushing down the fundus when a length of cord comes outside valve which remains permanent even after release of pressure.
