Correct Answer is A

Explanation

Choice A rationale:

This statement is incorrect. While continuous internal electronic fetal monitoring does limit mobility, it doesn’t require the woman to stay completely still.

Choice B rationale:

This is correct. An electrode may be inserted into the baby’s scalp to monitor heart rate.

Choice C rationale:

This is also correct. Internal monitoring provides the most accurate and continuous data about the baby’s heart rate.

Choice D rationale:

This is correct. The membranes must rupture before the electrode can be inserted.

A. Cephalhematoma. B. Vertex presentation. C. Caput Succedaneum. D. Molding.

Correct Answer is D

Explanation

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.
