One goal of therapy for sickle cell anemia is prevention of sickling phenomenon, which is responsible for the pathologic sequelae. Which of the following plan of care is directed toward the prevention of a crisis:
  1. Giving iron-rich formula as nourishment.
  2. Promoting oxygenation and hemodilution
  3. Techniques in decreasing tissue oxygen requirements and maintaining hemoconcentration
  4. Enforcing periods of bed rest to minimize energy expenditures.
Explanation
Answer: B - Because low oxygen tension precipitates sickling, therefore adequate oxygenation is desirable. Hemodilution prevents increased viscosity, which can cause sickling and thrombus formation. Bed rest is desirable during a pain episode, but not routinely employed in preventing crisis.
