The patient's temperature is 102.8°F (39.3°C), blood pressure is 110/70 mmHg, heart rate is 118 bpm, and respiratory rate is 24/min. The healthcare provider suspects bacterial meningitis. What is the nurse's highest priority action?

1. Obtain blood cultures before administering antibiotics
2. Administer prescribed antibiotics immediately after blood cultures are drawn **✔ 정답**
3. Prepare the patient for a lumbar puncture procedure
4. Implement droplet precautions and isolation measures

## 해설

In suspected bacterial meningitis, immediate antibiotic administration is critical to reduce mortality. While blood cultures are ideal, antibiotics should not be delayed. Other options are important but secondary to timely treatment.

Understanding the Clinical Priority in Suspected Bacterial Meningitis

The patient presents with a classic triad of acute meningitis: severe headache, neck stiffness (nuchal rigidity), and photophobia, accompanied by a high fever (102.8°F / 39.3°C) and tachycardia (118 bpm). In the context of suspected community-acquired bacterial meningitis (CABM), the clinical trajectory can be rapidly fatal due to the inflammatory cascade within the central nervous system. The nurse's highest priority is to facilitate the rapid initiation of antimicrobial therapy, as delays are directly linked to increased mortality and neurological sequelae.

The correct action is to administer prescribed antibiotics immediately after blood cultures are drawn. This sequence is critical. A foundational principle in sepsis and meningitis management is that obtaining cultures prior to antibiotic administration is essential for pathogen identification, but this diagnostic step must not significantly delay treatment. The study by Nielsen et al. (2026) on CABM highlights the diagnostic pathways, noting that pathogens are often identified through positive cerebrospinal fluid (CSF) cultures, PCR, or blood cultures with CSF pleocytosis [2]. If antibiotics are administered first, they can sterilize the blood and CSF, rendering cultures negative and leaving clinicians without a targeted treatment plan. However, the clinical decision rule evaluated by Lee et al. (2026) reinforces that in serious bacterial infections, the focus is on the timely administration of empirical intravenous antibiotics to improve outcomes [1]. Therefore, the nurse must coordinate the logistics so that blood cultures are drawn as a stat procedure and the prescribed broad-spectrum antibiotic is infused immediately afterward, without waiting for the results.

Let's analyze why the other options are not the highest priority action at this moment:

- Option 1 (Obtain blood cultures before administering antibiotics): While obtaining cultures before antibiotics is the correct sequence, this option is incomplete. It describes a step but fails to include the critical, time-sensitive intervention that must follow—the actual administration of the antibiotic. The priority is not just the culture but the rapid transition from culture to treatment.

- Option 3 (Prepare the patient for a lumbar puncture procedure): A lumbar puncture is essential for definitive diagnosis by analyzing CSF. However, it is a procedure that requires preparation, informed consent, and often physician assessment for signs of increased intracranial pressure. While the nurse may eventually prepare for this, it is not the immediate, life-saving nursing action. Antibiotic administration should not be withheld to perform a lumbar puncture; the first dose of empirical antibiotics is the most time-critical intervention.

- Option 4 (Implement droplet precautions and isolation measures): Infection control is a fundamental nursing responsibility. For suspected bacterial meningitis caused by organisms like Neisseria meningitidis, droplet precautions are indeed required. However, this is an administrative and environmental safety measure. The immediate physiological threat to this specific patient is the overwhelming infection and sepsis. The clinical priority framework dictates that an intervention directly addressing a life-threatening physiological instability (antibiotic administration for sepsis/meningitis) takes precedence over an indirect safety measure (isolation) that can be implemented concurrently by another team member or immediately after the first antibiotic dose is hung.

The clinical phenotypes of CABM described in the Danish cohort study underscore the severity and rapid progression of this disease, where prompt recognition and treatment are paramount [2]. The implementation of clinical decision rules, as studied by Lee et al. (2026), aims to streamline the identification of serious bacterial infections precisely to expedite such empirical treatment [1]. The nurse's role at the bedside is to translate this evidence into action by ensuring that the stat blood cultures are drawn and the first dose of a broad-spectrum antibiotic is administered without a moment's unnecessary delay.References (research sources)

## 임상 시나리오

Suspected Bacterial Meningitis: Immediate Nursing ActionsPrioritizing rapid antibiotic delivery after cultures
The highest priority for a patient with suspected bacterial meningitis is to administer empiric antibiotics as soon as possible. The critical window is within 1 hour of arrival.

To preserve diagnostic accuracy without causing a lethal delay, blood cultures must be drawn immediately before the first dose of antibiotics. Do not wait for lumbar puncture or imaging results.

A lumbar puncture for CSF analysis is essential but is secondary to antibiotics if it cannot be performed promptly. Administering antibiotics first may sterilize the CSF, but a delay in treatment increases mortality.

CautionImplement droplet precautions concurrently, but the life-saving intervention is antibiotic administration. Do not prioritize isolation over the medication pass.

## 핵심 개념

- **Nuchal Rigidity** — Neck stiffness and pain upon flexion, a classic sign of meningeal irritation indicating inflammation of the meninges.
- **Photophobia** — Sensitivity to light, a common symptom of meningitis resulting from irritation of the meninges and cranial nerves.
- **CSF Pleocytosis** — An increased number of white blood cells in the cerebrospinal fluid, indicative of infection or inflammation within the central nervous system.
- **Empiric Antibiotics** — Broad-spectrum antibiotics initiated before the specific causative pathogen is identified, based on the most likely organisms for the clinical syndrome.
- **Blood Culture Sterilization** — The process by which antibiotics kill bacteria in the bloodstream, making it impossible to grow and identify the pathogen from a blood sample drawn after administration.
