The parents of a 9-month-old infant tell the nurse that they have noticed foods such as peas and corn are not completely digested and can be seen in their infant’s stools. The nurse’s explanation of this is based on which statement? a. Child should not be given fibrous foods until digestive tract matures at age 4 years. b. Child should not be given any solid foods until this digestive problem is resolved. c. This is abnormal and requires further investigation. d. This is normal because of the immaturity of digestive processes at this age. ANS: D The immaturity of the digestive tract is evident in the appearance of the stools. Solid foods are passed incompletely broken down in the feces. An excess quantity of fiber predisposes the child to large, bulky stools. This is normal for the child and is a normal part of the maturational process; no further investigation is necessary
