Answer to Question 1

ANS: D
A synthetic food providing enough protein for growth and tissue repair, but little phenylalanine, is substituted for natural protein foods.

Answer to Question 2

ANS: B
Blood tests for phenylketonuria should be obtained 48 to 72 hours after birth. The newborn will have had enough time to ingest protein through feedings, and the chance of false-negative results will be reduced.
