Which nursing action should be implemented after a client has a lumbar puncture?

After a lumbar puncture, it is crucial to monitor the client for signs of headache because this is a common side effect that can occur due to changes in cerebrospinal fluid (CSF) pressure. A post-lumbar puncture headache may develop as the CSF leak leads to a drop in pressure, and it is typically characterized by a positional nature, worsening when sitting or standing and improving when lying down. By closely observing the client for any complaints of headache, healthcare providers can address this issue promptly, potentially implementing interventions such as hydration, analgesics, or even a blood patch if necessary.

Other actions such as encouraging ambulation immediately or remaining upright may not be recommended right after this procedure, as it is generally advised that clients rest and avoid certain movements to prevent complications. Administering fluids should be done appropriately based on the individual's condition, but it is not the primary action following a lumbar puncture compared to monitoring for headaches.
