Which of the following are NOT commonly associated with heat stroke?

Echinocytosis refers to the presence of echinocytes, or "burr cells," in the blood. This condition is typically associated with various electrolyte imbalances, certain diseases, and could occur due to factors such as hemolysis or artifacts during blood sampling. However, it is not widely recognized as a direct consequence of heat stroke.

Heat stroke primarily results in significant physiological changes due to hyperthermia, leading to complications such as coagulopathy and disseminated intravascular coagulation (DIC), which involve alterations in blood coagulation mechanisms. Urinary derangements can also arise due to the body's response to overheating, affecting kidney function and fluid balance.

In contrast, echinocytosis does not have a established link to heat stroke and its associated complications, reinforcing why it stands out as an option that is not commonly associated with this condition. This distinction helps to identify symptoms and complications that are more relevant in the context of heat stroke diagnosis and management.
