Sickle Cell Disease
Sickle Cell Disease ( 15 Questions)
The patient asks, "Why do my red blood cells become sickle-shaped?" Which response by the nurse is most accurate?
Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the HBB gene, leading to the production of abnormal hemoglobin called hemoglobin S (HbS) This abnormal hemoglobin causes red blood cells to become sickle-shaped when exposed to low oxygen levels, which is a hallmark of SCD. The nurse's response accurately reflects the genetic basis of this condition.
This choice is incorrect. Sickle-shaped red blood cells in SCD are not the result of an autoimmune reaction.
This choice is incorrect. Sickle-shaped red blood cells are not caused by a viral infection.
This choice is incorrect. Diet and lifestyle choices do not contribute to the sickle shape of red blood cells in SCD.
Choice A rationale:
Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the HBB gene, leading to the production of abnormal hemoglobin called hemoglobin S (HbS)
This abnormal hemoglobin causes red blood cells to become sickle-shaped when exposed to low oxygen levels, which is a hallmark of SCD.
The nurse's response accurately reflects the genetic basis of this condition.
Choice B rationale:
This choice is incorrect.
Sickle-shaped red blood cells in SCD are not the result of an autoimmune reaction.
Choice C rationale:
This choice is incorrect.
Sickle-shaped red blood cells are not caused by a viral infection.
Choice D rationale:
This choice is incorrect.
Diet and lifestyle choices do not contribute to the sickle shape of red blood cells in SCD.
