Final answer:
The proper placement of the tocotransducer for electronic fetal monitoring is at the maternal fundus.
Step-by-step explanation:
The proper placement of the tocotransducer for electronic fetal monitoring is at the maternal fundus. The maternal fundus refers to the top portion of the uterus, which is located above the vagina and behind the bladder in the center of the pelvis. Placing the tocotransducer at the maternal fundus allows for accurate monitoring of the fetal heart rate and contractions.
