In which clinical situation would the nurse most likely anticipate a fetal bradycardia?

Choice A rationaleCocaine is a stimulant that typically causes fetal tachycardia (an elevated fetal heart rate) due to its sympathomimetic effects, increasing maternal and subsequently fetal heart rate and blood pressure. It does not usually lead to fetal bradycardia.Choice B rationaleProlonged umbilical cord compression can lead to fetal bradycardia because it restricts oxygenated blood flow to the fetus. The baroreceptors in the fetus respond to decreased oxygen by slowing the heart rate in an attempt to conserve oxygen and maintain perfusion to vital organs.Choice C rationaleFetal anemia, a decrease in red blood cell count, can lead to fetal tachycardia as the heart attempts to compensate for reduced oxygen-carrying capacity by increasing cardiac output. Bradycardia is not a typical initial response to fetal anemia.Choice D rationaleTerbutaline is a tocolytic medication used to relax the smooth muscle of the uterus and prevent preterm labor. Its side effects often include maternal and fetal tachycardia due to its beta-adrenergic agonist activity.
