📚 Bacterial Meningitis — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Bacterial meningitis is an inflammation of the meninges covering the brain and spinal cord, most often caused by Neisseria meningitidis or Streptococcus pneumoniae. It is a medical emergency that can rapidly cause increased intracranial pressure, seizures, and death. It spreads through respiratory droplets, so prompt isolation and antibiotics are critical. Classic signs are fever, severe headache, nuchal rigidity, and photophobia.
🔑
Key points
Understand these first
Classic signs include sudden high fever, severe headache, nuchal rigidity (stiff neck), and photophobia.
A positive Kernig sign (pain on knee extension with hip flexed) and Brudzinski sign (involuntary knee flexion when neck is flexed) indicate meningeal irritation.
Altered level of consciousness, irritability, and seizures may occur as intracranial pressure rises.
Meningococcal meningitis can produce a petechial or purpuric rash.
Cerebrospinal fluid in bacterial meningitis is cloudy with high protein, low glucose, and high white cells.
✅
Nursing priorities
What to do, in order
Place the patient on droplet precautions immediately on suspicion, before confirmation.
Administer the first dose of prescribed antibiotics as quickly as possible, after blood cultures and lumbar puncture if feasible.
Monitor neurologic status and watch for signs of increased intracranial pressure.
Implement seizure precautions and provide a quiet, dimly lit environment for photophobia.
Monitor temperature and provide measures to reduce fever; maintain fluid and electrolyte balance.
🚩
Red flags — report now
Escalate immediately
Decreasing level of consciousness, widening pulse pressure, bradycardia, or abnormal posturing signals rising ICP, an emergency.
A spreading petechial/purpuric rash may indicate meningococcemia and septic shock, report immediately.
Seizures or sudden neurologic deterioration require urgent intervention.
Failure to maintain droplet isolation risks transmission to staff and others.
🧪
Labs & values
Numbers to know
CSF glucose (low in bacterial meningitis; normal ~40-70 mg/dL)
CSF protein (elevated in bacterial meningitis)
WBC (normal 5,000-10,000/mcL; elevated with infection)
🗣️
Patient teaching
What patients must know
Complete the entire course of prescribed antibiotics.
Close contacts may need prophylactic antibiotics, and vaccines (meningococcal, pneumococcal, Hib) help prevent meningitis.
Practice good hand hygiene and respiratory etiquette to reduce droplet spread.
❓ Bacterial Meningitis: NCLEX FAQs
What are the priority nursing interventions for Bacterial Meningitis?
Place the patient on droplet precautions immediately on suspicion, before confirmation. Administer the first dose of prescribed antibiotics as quickly as possible, after blood cultures and lumbar puncture if feasible. Monitor neurologic status and watch for signs of increased intracranial pressure. Implement seizure precautions and provide a quiet, dimly lit environment for photophobia.
What are the warning signs of Bacterial Meningitis a nurse must report?
Decreasing level of consciousness, widening pulse pressure, bradycardia, or abnormal posturing signals rising ICP, an emergency. A spreading petechial/purpuric rash may indicate meningococcemia and septic shock, report immediately. Seizures or sudden neurologic deterioration require urgent intervention. Failure to maintain droplet isolation risks transmission to staff and others.
