Step-by-step explanation:
If a casualty has clear yellow fluid leaking from the ears, nose, eyes, or mouth, it could indicate a serious medical condition known as a cerebrospinal fluid (CSF) leak. CSF is a clear, colorless fluid that surrounds and protects the brain and spinal cord. A CSF leak can occur due to head trauma, a skull fracture, or a tear in the tissues covering the brain or spinal cord.
CSF leaks can lead to symptoms such as persistent headaches, nausea, vomiting, neck stiffness, and changes in hearing or vision. It is important for a casualty with clear yellow fluid leaking from the ears, nose, eyes, or mouth to seek immediate medical attention for further evaluation and treatment.
