1. Overhydration.
2. Midrange altitudes.
3. Weight loss without dehydration.
4. Respiratory infection and dehydration.
4
Rationale:
1. Hydration should be encouraged; risk of overhydration is minimal.
2. High altitudes with lower oxygen concentrations pose a risk; mid-altitude is not a risk factor.
3. Weight loss is acceptable as long as hydration is maintained.
4. The child with sickle-cell disease is at risk for infection, and dehydration can precipitate crisis.
