In caring for a client following a head injury, the nurse plans to assess for rhinorrhea so that a sample can be tested for the presence of cerebrospinal fluid (CSF). At which location should the nurse observe for this finding? (Click the chosen location. To change, click on the new location.)

Site- the nose Rationale Rhinorrhea refers specifically to cerebrospinal fluid (CSF) rhinorrhea. This occurs when there is a leakage of CSF from the nose due to a fracture or injury to the skull base or surrounding structures, such as the cribriform plate. CSF is a clear fluid that surrounds and cushions the brain and spinal cord. When there is a fracture or disruption in the skull base, CSF can leak out through the nasal passages. This condition is concerning because it can increase the risk of infection, such as meningitis, due to the direct communication between the central nervous system and the external environment through the nasal cavity.
