B. Accelerations are increases in the fetal heart rate above the baseline. They are typically reassuring and indicate fetal well-being.
C. Late decelerations are concerning patterns in fetal heart rate monitoring. They can indicate poor oxygenation of the fetus and may be associated with conditions such as maternal hypotension, placental insufficiency, or other factors compromising blood flow to the fetus.
D. Variable decelerations are abrupt decreases in fetal heart rate that vary in timing, duration, and depth. They are often associated with umbilical cord compression, such as when the cord is being compressed or squeezed during contractions.
