What is a common consequence of untreated sickle cell anemia related to blood pH levels?

Untreated sickle cell anemia often leads to increased sickle cell crises, which are episodes of severe pain caused by the obstruction of blood flow due to sickled red blood cells. These cells have an abnormal shape that can clump together, leading to blockages in small blood vessels. This process can result in tissue hypoxia, acidosis, and further sickling of the cells; all of which contribute to a cycle of painful and potentially damaging crises.

Furthermore, during these crises, there is a consequential decrease in blood pH, leading to acidosis, which exacerbates the sickling phenomenon. The fluctuation in pH can indicate worsening conditions and prompt more crises, making management of blood pH critically important in patients with sickle cell disease. Thus, recognizing the relationship between untreated sickle cell anemia and the frequency of sickle cell crises is essential for nursing practice and patient care.

The other options do not accurately reflect the consequences of untreated sickle cell anemia. For instance, reduced anemia and improved oxygenation are not typically seen without treatment, and enhanced blood flow is counterproductive in the context of sickle cell pathology, where blood flow is often compromised.
