Answer to Question 1

A
Sickle cell disease has an autosomal recessive transmission pattern, which means that both parents must be carriers of the sickle cell trait. The sickle cell trait, not the disease itself, must be present in the parents for the child to have the disease.

Answer to Question 2

D
Iron supplements should be administered through a straw or by a medicine dropper placed at the back of the mouth because iron temporarily stains the teeth. A daily milk intake in toddlers of less than 24 ounces will encourage the consumption of iron-rich solid foods. Because food interferes with the absorption of iron, iron supplements are taken between meals. Administering this medication with foods rich in vitamin C facilitates absorption of iron. Apricots, dark-green leafy vegetables, and egg yolks are rich sources of iron. Other iron-rich foods include liver, dried beans, Cream of Wheat, iron-fortified cereal, and prunes.
