During a CST, the nurse observes variable decelerations of the FHR with or without contractions.
What does this finding indicate?
This finding indicates that the umbilical cord is being compressed, which can reduce the blood flow and oxygen supply to the fetus. Variable decelerations are abrupt decreases in the fetal heart rate (FHR) that vary in shape, duration, and degree of fall below the baseline. They are seen as W- or U-shaped waves on the monitor.
Fetal hypoxia is not indicated by variable decelerations, but by late decelerations, which are gradual decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends. Late decelerations are associated with uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen to the fetus.
Normal placental function is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability (6 to 25 beats per minute) and accelerations (increases in the FHR above the baseline). Normal placental function ensures adequate fetal oxygenation and well-being.
Adequate fetal oxygenation is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability and accelerations. Adequate fetal oxygenation means that the fetus is not experiencing hypoxia or distress. Normal ranges for FHR are 110 to 160 beats per minute at term and 120 to 160 beats per minute before term. Normal ranges for uterine contractions are 2 to 5 contractions in 10 minutes, lasting less than 90 seconds each.

Choice B is wrong because fetal hypoxia is not indicated by variable decelerations, but by late decelerations, which are gradual decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends.
Late decelerations are associated with uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen to the fetus.
Choice C is wrong because normal placental function is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability (6 to 25 beats per minute) and accelerations (increases in the FHR above the baseline).
Normal placental function ensures adequate fetal oxygenation and well-being.
Choice D is wrong because adequate fetal oxygenation is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability and accelerations.
Adequate fetal oxygenation means that the fetus is not experiencing hypoxia or distress.
Normal ranges for FHR are 110 to 160 beats per minute at term and 120 to 160 beats per minute before term.
Normal ranges for uterine contractions are 2 to 5 contractions in 10 minutes, lasting less than 90 seconds each.
