Trauma Nurse Core Course (TNCC) Practice Exam

Hypothermia is a significant concern in trauma patients primarily because it can complicate coagulopathy and adversely affect outcomes. When a patient experiences hypothermia, their body temperature drops, which can lead to impaired clotting functions. Decreased body temperature can reduce the effectiveness of coagulation factors and platelets, making it more difficult for the body to form clots. This is particularly critical in trauma situations where bleeding may already be a major concern.

The loss of temperature regulation can hasten the progression of trauma-associated coagulopathy, increasing the risk for hemorrhage and negatively impacting the patient's prognosis. In severe cases, this can culminate in a lethal triad of coagulopathy, acidosis, and hypothermia, which can lead to poorer outcomes and increased mortality rates. Therefore, maintaining normothermia is essential in the management of trauma patients to ensure optimal coagulation and overall recovery.

Options that suggest increased blood pressure, no significant effects, or rapid healing are not aligned with the recognized implications of hypothermia in trauma care and do not reflect the critical nature of managing a patient's body temperature in these situations.
