Answer to Question 1

ANS: C
Typical of this disease is a crying pattern that is abnormal and catlike. Cri du chat, or cat's cry, syndrome is a rare (one in 50,000 live births) chromosome deletion syndrome, not autosomal recessive, resulting from loss of the small arm of chromosome 5. In early infancy this syndrome manifests with a typical but nondistinctive facial appearance, often a moon-shaped face with wide-spaced eyes (hypertelorism). As the child grows, this feature is progressively diluted, and by age 2 years, the child is indistinguishable from age-matched control participants.

Answer to Question 2

ANS: D
Teratogens, agents that cause birth defects when present in the prenatal environment, account for the majority of adverse intrauterine effects not attributable to genetic factors. Types of teratogens include drugs (phenytoin Dilantin, warfarin Coumadin, isotretinoin Accutane). Heparin is the anticoagulant used during pregnancy and is not a teratogen. It does not cross the placenta.
