Final answer:
The statement that needs correction is the claim that sickle-cell anemia increases oxygen perfusion, as the disease actually causes a reduction in oxygen delivery to the tissues.
Step-by-step explanation:
The question relates to the understanding of sickle cell disease (SCD), which is a genetic blood disorder characterized by the production of abnormally shaped red blood cells (RBCs). These sickle-shaped cells have difficulty passing through small blood vessels, and contrary to one of the statements provided, they reduce oxygen perfusion into the blood due to their shape; they do not increase it. Sickle cell anemia patients may experience a range of symptoms, including painful episodes or crisises, anemia, and increased risk of infection. The life span of these RBCs is significantly reduced, leading to complications such as anemia, physical exertion, weakness, shortness of breath, and potentially leukemia or heart murmurs. Therefore, the statement from the client indicating that sickle-cell anemia increases oxygen perfusion into the blood suggests that further education is needed to correct misconceptions about the disease and to reinforce their therapeutic regimen. Medications can help manage the disease, but it is essential for patients to have accurate information to manage their health effectively.
