The skull is the most important factor in relation to the labor and birth processes.
The fetal skull must be small enough to travel through the bony pelvis.
What feature of the fetal skull helps to make this passage possible?
Cephalhematoma.
Vertex presentation.
Caput Succedaneum.
Molding.
The Correct Answer is D
Choice A rationale:
A cephalhematoma is a collection of blood that can occur under the scalp of a newborn. It does not aid in the passage of the fetal skull through the birth canal.
Choice B rationale:
Vertex presentation refers to the position of the fetus in the womb, not a feature of the skull that aids in birth.
Choice C rationale:
Caput succedaneum is a swelling of the scalp in a newborn. It is caused by pressure from the uterus or vaginal wall during a head-first (vertex) delivery, not a feature that aids in birth.
Choice D rationale:
Molding refers to the shaping of the fetal skull to fit through the birth canal. This is possible due to the presence of sutures and fontanelles in the skull, which allow the bony plates of the skull to move and overlap.

Constipation is not typically associated with lightening.

Explanation
Choice A rationale:
While placental abruption is a serious condition, it is not directly linked to high HbA1c levels in early pregnancy.

Choice C rationale:
Placenta previa is not directly associated with high HbA1c levels in early pregnancy.
Choice D rationale:
An incompetent cervix is not directly linked to high HbA1c levels in early pregnancy.
