Answer to Question 1

ANS: C
Wilson disease is manifested by dystonia and greenish-yellow rings in the cornea.
Galactosemia is manifested by high levels of blood galactose and vomiting. Fructosemia is mani-fested by high levels of blood fructose and hepatomegaly but not dystonia and rings in the cor-nea. Cirrhosis is manifested by hepatomegaly but not dystonia and greenish-yellow rings in the cornea.

Answer to Question 2

ANS: B
NEC includes feeding intolerance, abdominal distention, and bloody stools after 8-10 days of age, septicemia with elevated white blood cells, and falling platelet counts. Unstable temperature, bradycardia, and apnea are nonspecific signs. NEC is an ischemic, inflammatory condition of the bowel that causes necrosis, perforation, and death, if untreated. Infective enteropathy may be related to infection, but it is not necrotic. Mucoviscidosis is related to cystic fibrosis. Ileus is manifested by decreased bowel sounds but not ischemia.
