When preparing a woman for an amniocentesis, the nurse would instruct her to perform which action?.

Swallow the preprocedure sedative.

Empty the bladder.

Shower with an antiseptic scrub.

Lie on the left side.

Answer and Explanation

The Correct Answer is B

Swallowing a preprocedure sedative is not typically required for an amniocentesis. Sedatives can affect the mother and the fetus, and are usually avoided unless absolutely necessary.

Choice B rationale:

Emptying the bladder is important before an amniocentesis. A full bladder can push against the uterus, increasing the risk of puncturing the bladder during the procedure.

Choice C rationale:

Showering with an antiseptic scrub is not typically required before an amniocentesis. The area of the abdomen where the needle will be inserted is usually cleaned with an antiseptic by the healthcare provider.

Choice D rationale:

Lying on the left side is not typically required for an amniocentesis. The procedure is usually performed with the woman lying on her back.

Correct Answer is A

Explanation

Choice A rationale:

Physiologic anemia due to hemoglobin decrease does not cause dizziness when lying flat.

Choice B rationale:

A 50% increase in blood volume does not directly cause dizziness when lying flat.

Choice C rationale:

The gravid uterus can compress the vena cava when the woman lies flat, reducing blood flow to the heart and causing dizziness.

Choice D rationale:

Pressure of the presenting fetal part on the diaphragm can cause shortness of breath, but not dizziness.

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.
