A nurse on the labor and delivery unit is caring for a patient who is having induction of labor with oxytocin administered through a secondary IV line. Uterine contractions occur every 2
minutes, last 90 seconds, and are strong to palpation. The baseline fetal heart rate is 150/minute, with uniform decelerations beginning at the peak of the contraction and a return to baseline after the contraction is over.
Which of the following actions should the nurse take?
Increase the rate of infusion of the IV oxytocin,
Discontinue the infusion of the IV oxytocin.
Decrease the rate of infusion of the maintenance IV selution.
Slow the client's rate of breathing.
The Correct Answer is B
A. Incorrect. Increasing the rate of infusion of the IV oxytocin would worsen the uterine hyperstimulation and fetal distress that are indicated by the frequent, long, and strong contractions and uniform decelerations.
B. Correct. Discontinuing the infusion of the IV oxytocin would stop the uterine hyperstimulation and allow the fetus to recover from hypoxia.
C. Incorrect. Decreasing the rate of infusion of the maintenance IV solution would not affect the uterine hyperstimulation or fetal distress, as they are caused by the oxytocin, not by the fluid volume.
D. Incorrect. Slowing the client's rate of breathing would not help with the uterine hyperstimulation or fetal distress, as they are not related to maternal hyperventilation or respiratory alkalosis.

Correct Answer is D
Explanation
A) Retained bile in the liver results in delayed digestion: This statement is not related to the cause of heartburn.
B) Increased estrogen production causes increased secretion of hydrochloric acid: While hormonal changes during pregnancy can contribute to heartburn, it is specifically increased progesterone that leads to relaxation of the cardiac sphincter and delayed gastric emptying, which are more directly linked to heartburn.
C) Pressure from the growing uterus displaces the stomach: Uterine pressure on the stomach can lead to a feeling of fullness, but it is not the primary cause of heartburn during pregnancy.
D) Increased progesterone production causes relaxation of the smooth muscle relaxation of the cardiac sphincter and delayed gastric emptying: This is the correct answer. Increased progesterone levels during pregnancy relax the lower esophageal sphincter, leading to gastric acid reflux into the esophagus and causing heartburn.
Correct Answer is A
Explanation
A. Position the client on her side: Late decelerations are often associated with uteroplacental insufficiency, which may be improved by changing the maternal position to improve blood flow to the placenta.
B. Elevate the client's legs: Elevating the client's legs would not directly address the cause of late decelerations.
C. Increase the infusion rate of the IV fluid: While ensuring adequate hydration is important, it is not the priority action when late decelerations are noted.
D. Administer oxygen via a face mask: Oxygen administration may be necessary, but it is not the priority action. Positioning the client on her side to improve blood flow is the priority.
