One of the most elementary home interventions to help prevent a sickle cell crisis is to which of the following?

• A. Take iron supplements daily.
• B. Maintain adequate fluid intake.
• C. Engage in daily exercise.
• D. Eat leafy green vegetables.

Answer: (B)

Maintaining adequate fluid intake is a simple, effective way to reduce sickle cell crises because dehydration can trigger red blood cell sickling. When the body is dehydrated, blood becomes more viscous and hemoglobin S tends to polymerize, causing red cells to stiffen and obstruct small vessels. Keeping well hydrated helps keep the blood less viscous and the red cells more pliable, lowering the risk of vaso-occlusive events. This is especially important at home during illness, hot weather, or physical activity, when fluid losses are higher. Encourage regular fluids throughout the day and increase intake during fever, vomiting, diarrhea, or heavy sweating, while watching for signs of dehydration like dark urine or thirst. Iron supplements aren’t a preventive measure for crises unless there’s true iron deficiency, exercise can contribute to fluid losses if not balanced with fluids, and leafy greens don’t directly prevent crises.
