Answer to Question 1

D
The infant's kidneys are not as effective at concentrating urine compared with an adult's kidneys because of immaturity of the renal system and a slower glomerular filtration rates. The infant's metabolic rate is faster, not slower, than an adult's. Although the newborn infant's gastrointestinal system is immature, it is capable of digesting protein and lactase, but the ability to digest and absorb fat does not reach adult levels until approximately 6 to 9 months of age.

Answer to Question 2

D
Healthy attachment is manifested by stranger anxiety in late infancy. An infant who manifests stranger anxiety can be supported by the mother leaving the infant for only short periods of time. Assessing developmental needs is appropriate before taking an infant to a physician. Pain from teething expressed by the infant's cries would not occur only when the mother left the room.
