Prehospital Trauma Life Support (PHTLS) Practice Test

The most appropriate signs caregivers should observe during the evaluation of a trauma patient’s abdomen include rigidity, tenderness, distension, and referred pain. These findings are critical indicators of potential abdominal injury.

Rigidity may suggest peritonitis or internal bleeding, as the body often tenses the abdominal muscles in response to internal injury or irritation. Tenderness can indicate localized injury or inflammation, which can help identify which organs may be affected. Distension, or swelling of the abdomen, can signify internal bleeding, obstruction, or organ injury, while referred pain provides clues about damage to internal organs that may not be directly palpable.

The other options, while they may contain elements of an abdominal assessment, do not encompass the key clinical signs that are crucial for determining the severity of a trauma patient’s condition. Observing color changes or unusual sounds alone does not provide sufficient information about the potential injuries. Evaluating just the size and shape of the abdomen fails to capture the functional aspects of abdominal trauma. Lastly, while movement during breathing is a factor, it is not specific enough to suggest abnormality related to trauma without considering other signs.
