A nurse is caring for a client in labor who is experiencing incomplete uterine relaxation between hypertonic contractions.
What adverse effect does the nurse recognize as a result of this contraction pattern?
Reduced fetal oxygen supply
Delayed cervical dilation
Prolonged labor
Increased maternal stress.
The Correct Answer is B
Choice A rationale
While reduced fetal oxygen supply can occur with hypertonic contractions and inadequate uterine relaxation, it’s not the primary adverse effect. The main concern is the impact on the progress of labor.
Choice B rationale
This is the correct answer. Inadequate uterine relaxation between hypertonic contractions can delay cervical dilation, slowing the progress of labor.
Choice C rationale
Prolonged labor is not typically associated with hypertonic contractions and inadequate uterine relaxation. In fact, these conditions can lead to a more rapid labor.
Choice D rationale
Increased maternal stress can occur with any labor complication, but it’s not the primary adverse effect of hypertonic contractions and inadequate uterine relaxation.

Correct Answer is B
Explanation
Choice A rationale
Maternal bradycardia refers to a slower than normal heart rate in the mother. While it can affect the baby’s health, it doesn’t cause late decelerations on the fetal monitor.
Choice B rationale
Late decelerations are caused by uteroplacental insufficiency, which is a decrease in the blood flow to the placenta that reduces the amount of oxygen and nutrients transferred to the fetus. This is why the nurse would interpret late decelerations as indicating uteroplacental insufficiency.
Choice C rationale
Umbilical cord compression can cause variable decelerations, not late decelerations. Variable decelerations are abrupt decreases in the fetal heart rate, typically associated with contractions, and they vary in onset, depth, and duration.
Choice D rationale
Fetal head compression typically causes early decelerations, not late decelerations. Early decelerations are a mirror image of the contraction and are generally not a concern.
Correct Answer is D
Explanation
Choice A rationale
Indomethacin (Indocin) is a nonsteroidal anti-inflammatory drug (NSAID) that reduces fever, pain and inflammation. It is used to treat moderate to severe osteoarthritis, rheumatoid arthritis, gouty arthritis, or ankylosing spondylitis. It is not used to accelerate fetal lung maturity.
Choice B rationale
Nifedipine (Procardia) is a calcium channel blocker used to treat high blood pressure (hypertension) or chest pain (angina). It is not used to accelerate fetal lung maturity.
Choice C rationale
Calcium gluconate is used to prevent or to treat calcium deficiencies. It is not used to accelerate fetal lung maturity.
Choice D rationale
Betamethasone (Celestone) is a corticosteroid that is used to mature the lungs in fetuses at risk for preterm birth.
