A client with sickle cell anemia inquires the Health care provider. why the sickling crisis does not stop when oxygen therapy is started. Which explanation should the health care provider give to the client?
a. The main problem during a sickle cell crisis is destruction of the abnormal cells, resulting in fewer rbcs to carry oxygen.
b. Sickling occurs in response to decreased blood viscosity, which is not affected by oxygen therapy.
c. 02 therapy does not alter the shape of the abnormal erythrocytes but only allows for increased oxygen concentration in hemoglobin.
d. When RBCS sickle, they occlude small vessels, which causes more local hypoxia and more sickling.
