Meningitis nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Meningitis is inflammation of the meninges, most urgently from bacterial infection, and it presents with fever, severe headache, nuchal rigidity and photophobia. Suspect it whenever a patient cannot flex the neck to the chest without pain. Bacterial cases need droplet precautions until 24 hours of effective antibiotics have been given, and antibiotics should never wait on imaging or lumbar puncture results.
What it is and why it happens
Meningitis is inflammation of the meninges, the membranes covering the brain and spinal cord, and the cerebrospinal fluid between them. Bacterial meningitis is the emergency version: Neisseria meningitidis, Streptococcus pneumoniae and, in neonates, group B Streptococcus or Listeria are the usual culprits, and untreated bacterial disease can kill within hours. Viral meningitis is more common and generally self-limiting, caused by enteroviruses in most cases.
The organism reaches the meninges by bloodstream spread from a respiratory or ear infection, or by direct extension after neurosurgery, skull fracture, or a penetrating head injury. Once inside the subarachnoid space, the infection triggers an inflammatory response that raises intracranial pressure and can impair cerebral blood flow. That inflammatory cascade, not just the organism itself, is what drives the fever, headache and neurological signs you assess for at the bedside.
How it presents — what you will actually see
The classic triad is fever, headache and nuchal rigidity, and the finding that should stop you at the bedside is nuchal rigidity with photophobia and fever together. The patient resists neck flexion, often with pain radiating down the spine on passive flexion (a positive Brudzinski sign) or pain on leg extension with the hip flexed (a positive Kernig sign). Photophobia is frequently severe enough that the patient wants the room dark and the curtains drawn.
Beyond the triad, expect nausea, vomiting, and in bacterial cases a petechial or purpuric rash that does not blanch under pressure, particularly with meningococcal disease. Older adults and infants present atypically: an elderly patient may show only confusion or lethargy without classic neck stiffness, and an infant may show a bulging fontanelle, high-pitched cry, and poor feeding rather than a reportable headache. Altered level of consciousness, seizures, or focal neurological deficits signal a more severe course and need immediate escalation.
Nursing assessment priorities
Assess and document neurological status first, using the Glasgow Coma Scale and pupil response as your baseline, then reassess frequently since deterioration in bacterial meningitis can happen within a single shift. Check for nuchal rigidity, Kernig and Brudzinski signs, and inspect the skin fully for a petechial or purpuric rash, which points toward meningococcemia and changes the urgency of isolation and treatment.
Monitor vital signs closely, watching for the Cushing triad of widening pulse pressure, bradycardia and irregular respirations as a late sign of rising intracranial pressure. Track fluid balance and electrolytes, since syndrome of inappropriate antidiuretic hormone secretion is a recognised complication that can cause hyponatremia. Ask about recent respiratory illness, ear infection, sinusitis, or neurosurgical history, and confirm whether close contacts need prophylaxis if meningococcal disease is suspected.
Interventions and what to do first
The first action once bacterial meningitis is suspected is to start droplet precautions and obtain blood cultures, then give empiric intravenous antibiotics without waiting for lumbar puncture or imaging results. Every hour of delay in antibiotic administration is associated with worse outcomes, so this is not a step to defer for a CT scan unless the patient has signs of raised intracranial pressure or a focal deficit that make lumbar puncture unsafe before imaging.
Maintain droplet precautions, meaning a surgical mask for anyone within three feet, until the patient has completed 24 hours of appropriate antibiotic therapy and is clinically improving. Keep the room dim and quiet to reduce photophobia and headache, elevate the head of the bed to 30 degrees to support venous drainage, and minimise stimulation that could provoke seizures. Administer antipyretics and analgesics as ordered, monitor for signs of increased intracranial pressure, and have seizure precautions in place given the risk of cortical irritation.
Complications to watch for
Raised intracranial pressure is the complication that kills fastest, so watch for the Cushing triad, a deteriorating GCS score, and new pupillary changes, and escalate immediately if they appear. Hearing loss is a well-documented sequela of bacterial meningitis, particularly pneumococcal disease, so a formal hearing assessment before discharge is standard practice rather than optional.
Septic shock and disseminated intravascular coagulation can develop rapidly with meningococcemia, so a spreading petechial rash alongside hypotension needs the same urgency as a cardiac arrest call. Longer term, watch for seizure disorders, cognitive impairment, and hydrocephalus from impaired cerebrospinal fluid reabsorption. SIADH can persist into the recovery phase, so continue monitoring serum sodium even as the patient starts to improve clinically.
Patient teaching before discharge
Explain the full antibiotic course and why stopping early risks relapse or resistance, and confirm the patient understands which symptoms — recurring headache, fever, neck stiffness, or new confusion — mean they should return immediately rather than wait for the next outpatient appointment. Cover isolation guidance for household contacts if the meningitis was meningococcal, since close contacts may need prophylactic antibiotics arranged through public health.
Arrange follow-up hearing and neurological assessment, since deficits can be subtle and may only surface once the patient is back to normal activity. Discuss meningococcal and pneumococcal vaccination for the patient and household members where appropriate, particularly if a specific serotype was identified, and reinforce that fatigue and headache can linger for weeks after discharge without signalling relapse.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our neurological practice questions are the closest set to what this page covers.
Common questions
How long does droplet isolation last for bacterial meningitis?
Droplet precautions continue until the patient has received 24 hours of effective intravenous antibiotics. Anyone entering the room before that point should wear a surgical mask. After 24 hours of appropriate treatment with clinical improvement, standard precautions resume.
What is the difference between Kernig and Brudzinski signs?
Kernig sign is pain or resistance when the examiner extends the knee with the hip flexed to 90 degrees. Brudzinski sign is involuntary flexion of the hips and knees when the examiner passively flexes the patient's neck. Both suggest meningeal irritation but neither is sensitive enough on its own to rule meningitis out.
Why give antibiotics before the lumbar puncture results come back?
Bacterial meningitis can cause death or permanent neurological injury within hours, and delaying antibiotics to wait for culture confirmation measurably worsens outcomes. Blood cultures are drawn first, then empiric antibiotics start immediately, with therapy adjusted once cerebrospinal fluid results are available.
Does a normal CT scan mean lumbar puncture is safe?
A CT scan before lumbar puncture is only needed if the patient has focal neurological deficits, papilledema, a reduced level of consciousness, new-onset seizures, or an immunocompromised status, since these raise concern for a mass effect that could cause herniation on puncture. In a patient without those features, lumbar puncture can proceed without imaging, and antibiotics should not be delayed to obtain the scan regardless.
What is a common NCLEX trap with meningitis questions?
A frequent trap is choosing an intervention that delays antibiotics, such as waiting for a CT scan or lumbar puncture result before treating. The correct sequence is empiric antibiotics and droplet precautions first, with diagnostic confirmation running in parallel, not before.
