What is a typical indication for using a heavy blanket on a trauma patient?

The use of a heavy blanket on a trauma patient primarily serves the purpose of providing warmth to manage hypothermia. Trauma patients are particularly susceptible to hypothermia due to factors such as exposure during an accident, blood loss, and the body’s stress response. Keeping the patient warm is crucial not only for comfort but also to prevent hypothermia, which can complicate their condition and hinder recovery.

Maintaining a stable body temperature can support the body's metabolic processes and promote better outcomes in terms of healing and recovery from trauma. While the other options might address important aspects of patient care, warmth management plays a critical role in the immediate treatment of trauma patients.
