A nurse is discussing fetal oxygenation during labor of a client with the RN. As the client progresses through the first stage of labor, which of the following client physiologic adaptations should the nurse identify as promoting fetal oxygenation?

Elevated client blood pressure during contractions

Decrease in client blood volume

Increased client cardiac output

Client bradypnea

Answer and Explanation

The Correct Answer is C

A. Elevated client blood pressure during contractions – Incorrect; high BP can reduce uteroplacental circulation, affecting fetal oxygenation.

B. Decrease in client blood volume – Incorrect; a drop in blood volume would compromise oxygen delivery.

C. Increased client cardiac output – Correct; cardiac output increases during labor to enhance blood flow to the placenta, improving fetal oxygenation.

D. Client bradypnea – Incorrect; slow breathing (bradypnea) can lead to hypoxia, reducing fetal oxygen supply.

C. Environmental – Correct; radiation and pollutants can affect fetal development.

D. Emotional stress – Incorrect; while stress affects pregnancy outcomes, it is not classified as a teratogen.

E. Infections – Correct; infections such as rubella, toxoplasmosis, and syphilis can cause severe congenital abnormalities.

A. Fundus soft, 2 fingerbreadths below the umbilicus B. Fundus firm, 2 fingerbreadths above the umbilicus C. Fundus soft, to the right of the umbilicus D. Fundus firm, at the level of the umbilicus

Correct Answer is D

Explanation

A. Fundus soft, 2 fingerbreadths below the umbilicus – Incorrect; the fundus should be firm, not soft, to prevent postpartum hemorrhage.

B. Fundus firm, 2 fingerbreadths above the umbilicus – Incorrect; a fundus above the umbilicus at 12 hours may indicate bladder distension or uterine atony.

C. Fundus soft, to the right of the umbilicus – Incorrect; a deviated and soft fundus suggests bladder distension, requiring intervention.

D. Fundus firm, at the level of the umbilicus – Correct; at 12 hours postpartum, the fundus should be firm and at the level of the umbilicus, gradually decreasing in height each day.
