What statement indicates that an adolescent with sickle cell anemia understands their condition?

The statement indicating that an adolescent with sickle cell anemia understands their condition is the one that emphasizes the importance of hydration. Individuals with sickle cell anemia are at a higher risk for complications such as sickle cell crisis, which can be precipitated by dehydration, among other factors. By recognizing that drinking more fluids can help prevent symptoms, the adolescent demonstrates an understanding of how proper hydration can contribute to overall health management and symptom prevention in their specific condition.

Hydration is crucial because it helps to keep the blood less viscous, reducing the likelihood of red blood cells sickling and causing blockages in blood vessels. This proactive approach reflects a good understanding of the self-management aspects necessary in dealing with sickle cell anemia.

The other statements do not convey a correct understanding of the condition and its management. For example, thinking that eating less food is beneficial or that symptoms only arise from stress does not demonstrate a comprehensive understanding of the factors affecting sickle cell anemia. Additionally, believing that medication alone will eliminate symptoms overlooks the importance of other preventive measures like hydration and managing stress levels.
