During labor, which of the following is a characteristic of early decelerations in fetal heart rate?

A. To determine the exact gestational age of the fetus. Gestational age is estimated via ultrasound and fundal height, not an NST.

B. To measure the amniotic fluid volume. Amniotic fluid volume is assessed with an ultrasound and amniotic fluid index (AFI), not an NST.

C. To confirm the presence of labor contractions. An NST does not confirm labor contractions; it evaluates fetal heart rate in response to fetal movement.

D. To assess fetal well-being in cases of suspected fetal growth restriction. An NST evaluates fetal oxygenation and well-being, making it useful in cases of intrauterine growth restriction (IUGR) or other concerns about fetal health.

A. Increase the client's IV fluid infusion rate. While increasing IV fluids can improve placental perfusion, the priority intervention for late decelerations is repositioning the client to relieve uteroplacental insufficiency.

B. Palpate the client's uterus. Uterine palpation helps assess for tachysystole (excessive contractions), which could contribute to late decelerations. However, this is not the priority intervention.

C. Administer oxygen to the client. Oxygen administration (8-10 L/min via face mask) improves fetal oxygenation, but repositioning the client should be done first to relieve pressure on the placenta.

D. Turn the client onto her side. Repositioning the client to the left or right lateral position improves uteroplacental circulation and reduces compression of the inferior vena cava, increasing blood flow to the fetus.
