## 문제

A nurse is caring for a patient with bacterial meningitis who is receiving IV antibiotics. Which nursing intervention is the highest priority to prevent complications?

A 28-year-old patient was admitted with bacterial meningitis and is receiving IV ceftriaxone. The patient exhibits nuchal rigidity, photophobia, and altered mental status.

## 보기

1. Monitor vital signs every 4 hours
2. Maintain strict intake and output records
3. Implement seizure precautions immediately **✔ 정답**
4. Administer prescribed analgesics for headache

**정답: 3**

## 해설

Seizure precautions are the highest priority due to increased intracranial pressure and cerebral irritation in bacterial meningitis, which can lead to sudden seizures. Other interventions are important but address less immediate risks.

Clinical Context and Priority Setting

This patient presents with classic signs of bacterial meningitis: nuchal rigidity, photophobia, and altered mental status. While all listed interventions are relevant to the care of a patient with meningitis, the question asks for the highest priority intervention to prevent complications. In NCLEX-RN prioritization, a patient with an acute neurological infection and altered mental status is at immediate risk for life-threatening complications that can cause irreversible harm within minutes.

Why Seizure Precautions Are the Priority

Bacterial meningitis causes inflammation of the meninges and underlying cerebral cortex. This inflammatory process, driven by bacterial invasion and the host immune response, leads to neuronal irritation, cytotoxic edema, and increased intracranial pressure (ICP). The resulting cortical irritability significantly lowers the seizure threshold . A seizure in a patient with altered mental status and potential airway compromise can rapidly lead to hypoxia, aspiration, and further elevation of ICP. The Neurohospitalist Core Competencies emphasize that managing acute neurological conditions requires anticipating and preventing secondary brain injury, with seizure control being a fundamental component of neurocritical care . Implementing seizure precautions—such as padding side rails, ensuring suction equipment and oxygen are at the bedside, and keeping the bed in the lowest position—is a direct safety intervention that mitigates the risk of physical injury and physiological decompensation should a seizure occur.

Analysis of Other Options

- Monitor vital signs every 4 hours: Monitoring is essential for detecting hemodynamic instability or signs of increased ICP, such as Cushing's triad. However, a 4-hour interval is not frequent enough for a patient with an acute neurological infection and altered mental status, who requires more continuous neurological assessment. Furthermore, monitoring is a form of assessment; the priority intervention is an action that directly prevents a foreseeable and immediate complication.

- Maintain strict intake and output records: Fluid balance is important, particularly if the patient develops syndrome of inappropriate antidiuretic hormone (SIADH), a known complication of meningitis. However, this intervention addresses a complication that develops over hours to days. It does not take precedence over preventing an immediate safety threat like a seizure.

- Administer prescribed analgesics for headache: Pain management is a comfort and nursing care need, but it is not the highest priority when a patient has an altered level of consciousness and is at high risk for seizure activity. The physiological threat of a seizure outweighs the need for analgesia in the immediate prioritization framework.

Pathophysiology and Clinical Correlation

The altered mental status in this patient is a critical clinical clue. It indicates that the infection is not confined to the meninges but is affecting cerebral function, which can be due to meningoencephalitis, elevated ICP, or both [1,2]. The primary amoebic meningoencephalitis case report highlights how rapidly progressive central nervous system infections mimic bacterial meningitis and cause profound neurological decline, reinforcing the need for aggressive supportive care and complication prevention from the moment of admission . The inflammatory cascade triggered by the pathogen lysing in response to IV ceftriaxone can initially worsen cerebral edema and irritation, further heightening seizure risk. Therefore, preparing for a seizure is a non-delegable, immediate nursing action that protects the patient from a cascade of secondary injuries.

Seizure Precautions in MeningitisImmediate Safety Intervention for Cortical Irritability
Bacterial meningitis causes cortical irritability and cytotoxic edema, which significantly lower the seizure threshold. A seizure in a patient with altered mental status can rapidly lead to hypoxia, aspiration, and increased intracranial pressure (ICP).

Implement seizure precautions immediately: pad side rails, ensure suction equipment and oxygen are at the bedside, and keep the bed in the lowest position. This is the highest priority to prevent secondary brain injury.

CautionDo not delay precautions for vital signs or medication administration. A seizure in an altered patient with nuchal rigidity poses an immediate risk of airway compromise and irreversible neurological decline.

## 핵심 개념

- **Nuchal rigidity** — Stiff neck with pain on flexion, a classic sign of meningeal irritation indicating inflammation of the meninges.
- **Seizure threshold** — The balance between excitatory and inhibitory forces in the brain; lowered by cortical irritation from infection, increasing seizure risk.
- **Cortical irritability** — A state of neuronal hyperexcitability caused by inflammation, edema, or infection, predisposing the brain to seizure activity.
- **Secondary brain injury** — Additional neurological damage occurring after the initial insult, often from hypoxia, hypotension, or increased ICP.
- **Seizure precautions** — Safety measures including padded side rails, suction setup, oxygen availability, and bed in lowest position to prevent injury during a seizure.
