Question

Quizplus · Accepted Answer

Contusions typically involve hemorrhage and hematoma, which can occur when the brain slams against the inside of the skull due to a traumatic impact. Contusions do not necessarily involve a puncture from a sharp object, so option A is incorrect. Option D is too broad, as it includes option C, which is the specific mechanism of injury that leads to contusions. Therefore, the most accurate answer is E, which identifies both the specific mechanism of injury and the resulting types of damage.
