Answer to Question 1

A
The risks are related to the chemicals used in dry-cleaning that can be teratogens. Working as a high school teacher or office secretary should not pose any hazard to pregnancy. While gasoline fumes can be hazardous, part-time work as a bus driver should pose only minimal hazard, if any.

Answer to Question 2

D
Hyperbilirubinemia is associated with neurologic injury, including hearing loss. Hyperglycemia does not result in hearing loss. Hypocalcemia may be associated with polycythemia, but not hearing loss. Polycythemia may be associated with hypocalcemia, but not hearing loss.
