Feedback
A A similar dose of a topical medication administered to an infant compared with
an adult is approximately three times greater in the infant because of the greater
body surface area.
B Infants and young children have a thinner outer skin layer (stratum corneum),
which increases the absorption of topical medication.
C The smaller muscle mass in infants affects site selection for injected
medications, but should not affect administration of topical medications.
D The young child's skin is more prone to irritation, making contact dermatitis and
other allergic reactions more common.
