A nurse is observing the electronic fetal heart rate monitor tracing for a client who is at 40 weeks of gestation and is in labor.
The nurse should suspect a problem with the umbilical cord when she observes which of the following patterns?.
Variable decelerations.
Early decelerations.
Accelerations.
Late decelerations.
The Correct Answer is A
The correct answer is choice A.
Choice A rationale:
Variable decelerations are associated with problems with the umbilical cord, such as compression. This is because they occur irregularly and can happen at any time during the contraction cycle.
Choice B rationale:
Early decelerations are usually benign and are associated with fetal head compression during a uterine contraction. They are not typically indicative of a problem with the umbilical cord.
Choice C rationale:
Accelerations are usually a sign of fetal well-being and are not typically associated with umbilical cord issues.
Choice D rationale:
Late decelerations are associated with 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. They are not typically indicative of a problem with the umbilical cord.
