What are known triggers for vaso-occlusive crises, such as Sickle Cell Disease?
Alkalosis and insomnia
Reduced stress and warm environmental temperature
Acidosis and dehydration
High fat diet and hyperoxia
The Correct Answer is C
A. Alkalosis and insomnia:
Alkalosis does not trigger sickling; acidosis (low pH) is more harmful. Insomnia alone is not a direct trigger.
B. Reduced stress and warm environmental temperature:
Reduced stress and warmth help prevent crises rather than cause them.
C. Acidosis and dehydration:
Acidosis promotes sickling of RBCs, and dehydration increases blood viscosity, both triggering vaso-occlusive crises.
D. High fat diet and hyperoxia:
A high-fat diet is linked to cardiovascular disease, and hyperoxia (excess oxygen) is not a trigger for sickling.
