c. Muscle wasting, diarrhea, low hemoglobin, and infection
characterize kwashiorkor
d. Subcutaneous fat, hepatomegaly, and fatty liver are present in
kwashiorkor. - ANSWER-ANS: D
The presence of subcutaneous fat, hepatomegaly, and fatty liver
distinguishes kwashiorkor from marasmus. These manifestations
are missing in marasmus because caloric intake is not sufficient
to support fat synthesis and storage. None of the other options
accurately describes the differences among these conditions.
