Answer to Question 1

ANS: D
The direct Coombs' test determines whether the infant has hemolytic disease caused by Rh incompatibility by revealing the presence of antibody-coated Rh-positive red blood cells in the baby's blood. An indirect Coombs' test measures the amount of Rh-positive antibodies in the mother's blood.

Answer to Question 2

ANS: C
High-intensity light decreases bilirubin levels by converting unconjugated bilirubin into photobilirubin, which is transported to the liver where it combines with bile and is excreted in the feces.
