Which of the following is a component of the DCAP-BTLS assessment?

The correct choice of swelling as a component of the DCAP-BTLS assessment highlights an important aspect of trauma evaluation. DCAP-BTLS stands for Deformities, Contusions, Abrasions, Penetrations, Burns, Tenderness, Lacerations, and Swelling. Swelling indicates inflammation or injury to tissues and can be crucial in assessing the extent of trauma in a patient. Noticing swelling during an assessment allows healthcare providers to identify areas that may require immediate attention or further investigation.

While other aspects such as respiratory sounds, altered mental status, and skin color variations may be significant in a broader patient assessment, they do not specifically fall under the defined terminology of the DCAP-BTLS framework. This framework is specifically tailored for evaluating injuries sustained in trauma situations, and swelling directly corresponds to visible physical changes in the tissues that signal potential underlying issues.
