Answer to Question 1
ANS: B
Physiologically and developmentally, the 4- to 6-month-old infant is in a transition period. The extrusion reflex has disappeared, and swallowing is a more coordinated process. In addition, the gastrointestinal tract has matured sufficiently to handle more complex nutrients and is less sensitive to potentially allergenic food. Infants of this age will try to help during feeding; 2 to 3 months is too young. The extrusion reflex is strong, and the child will push food out with the tongue. No research indicates that the addition of solid food to a bottle has any benefit. Infant birth weight doubles at 1 year. Solid foods can be started earlier. Tooth eruption can facilitate biting and chewing; most infant foods do not require this ability.
Answer to Question 2
ANS: A
Health practices should be most important. With the need for diaper changes and assistance with feeding, young children are at increased risk when hand washing and other hygienic measures are not adhered to. A structured learning environment is not suitable for this age child. The socioeconomic status of children should have little effect on the choice of facility. Cultural similarities of children may be important to the families, but the health care practices of the facility are more important.
