Explanation: 1. Maternal hypotension results in decreased blood flow to the fetus.
2. Cord compression can cause fetal bradycardia.
3. This will cause fetal bradycardia if there is a fetal heart block.
5. This is a depression of myocardial activity.

Answer to Question 2

1, 3, 5
Explanation: 1. During implantation, the trophoblast attaches itself to the surface of the endometrium for further nourishment.
3. Between days 7 and 10 after fertilization, the zona pellucida disappears, and the blastocyst implants itself by burrowing into the uterine lining and penetrating down toward the maternal capillaries until it is completely covered.
5. The cells of the trophoblast grow down into the thickened lining, forming the chorionic villi.
