Meconium staining specifically denotes the presence of meconium, which is the earliest stool of a newborn, in the amniotic fluid surrounding the fetus. This phenomenon can occur during labor, particularly if the fetus is under stress, resulting in the fetus passing meconium prior to birth. When meconium is present in the amniotic fluid, it can have implications for the newborn, such as the risk of meconium aspiration syndrome, where the meconium gets inhaled into the lungs during or after delivery, leading to potential respiratory issues.

The other options describe different conditions that are not directly related to the specific term "meconium staining." Abnormal fetal heart rate patterns indicate issues with fetal distress or well-being, defects in the placenta pertain to structural abnormalities affecting fetal development, and fluid leaking from the placenta describes a rupture of membranes, which can occur independent of meconium presence. Therefore, the definition of meconium staining aligns solely with the presence of fetal stool in the amniotic fluid.
