What is the priority action for a nurse after a lumbar puncture in a patient with suspected bacterial meningitis?

After a lumbar puncture in a patient with suspected bacterial meningitis, placing the patient on droplet precautions is a critical priority. Bacterial meningitis is highly contagious and can be transmitted through respiratory droplets when an infected individual coughs or sneezes. Implementing droplet precautions helps prevent the spread of the infection to others, including healthcare workers and patients in the vicinity.

While the other options may be relevant in the management of the patient's overall care, maintaining infection control is paramount in the context of suspected bacterial meningitis. It is essential to ensure that appropriate measures are in place to protect both the patient and others from potential exposure, making it a top priority immediately following the procedure.
