Question: 1 / 400

What does the "E" in the ABCDE mnemonic signify?

Exposure (undressing the patient to assess for hidden injuries)

The "E" in the ABCDE mnemonic stands for Exposure, which emphasizes the importance of undressing the patient to thoroughly assess for hidden injuries. In trauma care, it is crucial to conduct a complete physical examination to identify any injuries that may not be immediately visible, such as those that could be concealed by clothing or other barriers. This step is vital, as missing concealed injuries can lead to significant complications in patient management.

Undressing the patient must be done while ensuring their dignity and warmth, often using blankets to prevent hypothermia. By evaluating the entire body surface, healthcare providers increase the likelihood of detecting injuries like lacerations, contusions, or fractures that may otherwise go unnoticed. This comprehensive assessment plays a critical role in guiding further treatment and interventions in a trauma scenario.
