A client postoperatively with an external ventricular drain shows which assessment that is most concerning: CSF appears cloudy?

• A. CSF appears clear
• B. CSF is colorless
• C. CSF appears cloudy
• D. CSF is slightly bloody

Answer: (C)

Recognizing infection risk with an external ventricular drain is essential because this setup provides a direct route for microorganisms into the ventricles. When CSF appears cloudy, it suggests purulent material and an infectious process such as ventriculitis or meningitis, which can rapidly worsen and lead to increased intracranial pressure or sepsis. Clear or colorless CSF is more typical of noninfectious postoperative drainage, while slightly bloody CSF can occur after catheter placement and often resolves. Therefore, cloudy CSF is the most concerning finding and requires immediate evaluation—promptly notify the healthcare team, obtain CSF cultures if ordered, ensure the drain system remains sterile, and monitor for fever, neck stiffness, or other signs of infection while initiating or adjusting treatment as indicated.
