Which is NOT listed as a risk factor for rhabdomyolysis?

• A. Crush injury
• B. Hyperthermia
• C. Immobilization
• D. Hypothermia

Answer: (B)

Rhabdomyolysis happens when muscle cells break down and release their contents into the bloodstream. Certain conditions reliably increase that risk: direct muscle trauma (crush injuries) causes immediate muscle damage; prolonged immobilization reduces blood flow to muscles, leading to ischemia and cellular injury; extreme temperatures can injure muscle tissue—both heat-related injury (hyperthermia/heat stroke) and cold-related injury (hypothermia) can contribute. In this question’s context, the given list includes crush injury, immobilization, and hypothermia as risk factors, but hyperthermia is not listed. Therefore hyperthermia is the one that isn’t considered a listed risk factor in this item, making it the correct choice. Note that in broader clinical knowledge, heat-related rhabdomyolysis is a recognized cause, but the prompt here reflects a specific source's listed factors.
