Final answer:
In a child with nonorganic failure to thrive, the nurse would expect to see developmental delays, not rapid weight gain, excessive height, or hyperactivity, due to factors such as undernutrition affecting growth.
Step-by-step explanation:
The nurse would expect to find developmental delays in a child admitted for nonorganic failure to thrive. Nonorganic failure to thrive is a diagnosis given to children whose growth is significantly below that of their age and sex peers and is not due to an organic disease. Such children are often undernourished and may present with delayed developmental milestones due to inadequate calorie intake or psychosocial factors affecting their growth. This definition excludes expected findings such as rapid weight gain or hyperactivity, which are not typical of nonorganic failure to thrive condition. In contrast, children who experience rapid growth, particularly in weight, might face other health issues like type 2 diabetes or heart disease, reflective of a divergence from normal growth patterns.
