Answer to Question 1

ANS: B
Fragile X syndrome is the most common inherited cause of cognitive impairment and the second most common genetic cause of cognitive impairment after Down syndrome. Fragile X primarily affects males and follows the pattern of X-linked dominant inheritance with reduced penetrance.

Answer to Question 2

ANS: D
The constant stuffy nose forces the child to breathe by mouth, drying the mucous membranes and increasing the susceptibility to upper respiratory tract infections. A cool-mist vaporizer will keep the mucous membranes moist and liquefy secretions. Respiratory tract infections combined with cardiac anomalies are the primary cause of death in the first years. The child has a protruding tongue, which makes feeding difficult. The parents must persist with feeding while the child continues the physiologic response of the tongue thrust. The child is predisposed to constipation. Calories should be appropriate to the child's weight and growth needs, not mental age.
