Question

Which of the following conditions can trigger a sickle crisis in individuals with sickle cell anemia?

A) High oxygen levels
B) Adequate hydration
C) Hypoxia, dehydration, or acidosis
D) Normal pH levels

Answer 1

Sickle cell anemia is a genetic disorder that can trigger a sickle crisis in individuals under certain conditions. These conditions include hypoxia, dehydration, or acidosis, which reduce the ability of sickle-shaped red blood cells to deliver oxygen to tissues and can cause blockages in capillaries.

Step-by-step explanation:

Sickle cell anemia is a genetic disorder caused by the production of abnormal hemoglobin, resulting in the characteristic sickle-shaped red blood cells. A sickle crisis can be triggered by conditions such as hypoxia (low oxygen levels), dehydration, or acidosis (low pH levels). These conditions reduce the ability of the sickle-shaped red blood cells to deliver oxygen to tissues, causing them to become stuck in narrow capillaries and blocking blood flow.
