Lumbar puncture: which nursing observation would be of most concern?

• A. Oozing fluid on the injection site.
• B. Mild post-procedure headache.
• C. Back discomfort.
• D. Normal vital signs.

Answer: (A)

A CSF leak from the puncture site is the most concerning finding after a lumbar puncture. Oozing clear fluid at the injection site signals that CSF may be escaping, which can lower intracranial pressure and increase the risk of a persistent headache and, more importantly, meningitis if infection enters through the tract. This requires prompt assessment and intervention by the nurse and timely notification of the provider. By contrast, a mild post-procedure headache is common and usually self-limited, back discomfort is expected, and normal vital signs are reassuring. The key is recognizing the CSF leak sign and treating it as a potential complication.
