Final answer:
The symptoms in a 2-year-old child with iron-deficiency anemia are related to the effects of anemia itself, including a decrease in hemoglobin production and a lack of oxygen in the blood.
Step-by-step explanation:
The symptoms of anorexia, vomiting, weight loss, and restlessness in a 2-year-old child with iron-deficiency anemia are most likely related to the effects of the anemia itself.
Iron-deficiency anemia is caused by a deficiency of iron in the diet or an inability to absorb and transport iron. This can lead to a decrease in hemoglobin production, which affects the oxygen-carrying capacity of the blood.
The lack of oxygen caused by iron-deficiency anemia can result in symptoms such as poor appetite, vomiting, weight loss, and restlessness in young children.
