Question 1 of 5
A nurse monitors fetal well-being by means of an external monitor. At the peak of the contractions, the fetal heart rate has repeatedly dropped 30 beats/min below the baseline. Late decelerations are suspected and the nurse notifies the physician. Which is the rationale for this action?
Correct Answer: D
Rationale: The correct answer is D because late decelerations are associated with uteroplacental insufficiency, indicating fetal hypoxia. During contractions, the placenta may not be receiving enough oxygen and nutrients, leading to decreased oxygen supply to the fetus, resulting in late decelerations. Repeated late decelerations indicate ongoing fetal distress and the need for immediate intervention to prevent further complications.
Choices A, B, and C are incorrect because they do not accurately reflect the characteristics and causes of late decelerations. A nuchal cord is associated with variable decelerations, not late decelerations. Variable decelerations are due to cord compression, not late decelerations. Late decelerations are indeed a result of hypoxia, but they are specifically related to uteroplacental insufficiency, not reflective of the strength of maternal contractions.
