Final answer:

Secondary injuries from a blast include impaled objects, which are caused by debris propelled at high velocities due to the blast. These injuries, along with extremity fractures, liver lacerations, and lung injuries, are a result of the debris and forceful impact following the initial blast wave. The correct option is C .

Step-by-step explanation:

The student's question pertains to the types of injuries that can be classified as secondary injuries from a blast. Secondary injuries are caused by being struck by flying debris or by being thrown against objects following the initial blast wave. These injuries can result in a range of trauma, including lacerations, fractures, and the embedding of impaled objects within the body. Specifically:

  • Extremity fractures: These could occur when the limbs are forcibly struck by debris or when a person is thrown by the blast force and lands awkwardly, causing the bones to break.
  • Impaled objects: Objects propelled at high velocities due to the blast can become embedded within the body, potentially causing deep puncture wounds.
  • Liver lacerations: When debris strikes the abdomen with significant force, it can cause cuts or tears (lacerations) in the liver or other internal organs.
  • Lung injuries: The lungs are sensitive to changes in pressure and can be injured by the blast wave itself or by debris impacting the chest area.

Given the context of the question, the correct answer is B. impaled objects, as they are indeed a type of secondary injury that can occur from a blast, where debris or fragments can cause penetrating injuries after the initial explosion. Such injuries could be caused by sharp objects propelled toward the victim with a high degree of force.
