and complication prevention.
What medications and interventions are used for sickle cell anemia? Right
Ans - IV fluids, hydroxyurea, transfusions.
Why is 5% dextrose preferred for IV fluids in sickle cell anemia? Right Ans
- Decreased ability to excrete sodium load in normal saline.
What is hydroxyurea? Right Ans - A medication that makes sickle red blood
cells less sticky.
What is the effect of hydroxyurea in sickle cell anemia? Right Ans - Reduces

What should be considered when using oxygen therapy in sickle cell anemia?
Right Ans - May suppress the formation of new RBCs.
,What is anemia? Right Ans - Lower than normal hemoglobin and fewer
than normal circulating erythrocytes.
What can cause hemolytic anemia? Right Ans - Altered erythropoiesis,
drug-induced or autoimmune processes, or mechanical heart valves.
What is SCD? Right Ans - Inheritance of sickle hemoglobin (HbS) gene

What is glucose 6 phosphate dehydrogenase deficiency? Right Ans -
Hereditary condition where RBCs are destroyed when exposed to certain
triggers.
What is autoimmune hemolytic anemia? Right Ans - Body destroys RBCs
faster than it produces them.

management and complication prevention.
Is there a cure for sickle cell anemia? Right Ans - No, but bone marrow and
stem cell transplants are potential options.
What is the purpose of transfusions in sickle cell anemia? Right Ans - To
replace sickled RBCs with healthy ones.
