What type of injury would require the use of skin closure applications?

The correct answer is lacerations, as they are characterized by cuts or tears in the skin that can range from superficial to deep. When a laceration occurs, it is crucial to properly close the wound to promote healing and prevent infection. Skin closure applications, such as sutures, staples, adhesive strips, or glue, are specifically designed to bring the edges of the lacerated skin together, facilitating the healing process.

In contrast, fractures involve broken bones and typically require immobilization or realignment rather than skin closure. Non-healing wounds may present a need for assessment and potentially other treatments, but they do not fall into the category that directly relates to skin closure applications in the same way lacerations do. Contusions, or bruises, involve bleeding under the skin without a break in the skin integrity, thus not requiring any form of closure.
