## 문제

A charge nurse is managing multiple critical situations during a night shift when a severe weather emergency causes power outages and staffing shortages. Which action should the charge nurse prioritize first?

## 보기

1. Immediately respond to Unit D to assess the patient with chest pain and abnormal ECG changes
2. Prioritize Unit A to ensure immediate backup ventilation for the ventilator-dependent patient **✔ 정답**
3. Go to Unit C to evaluate the patient who fell and assess for potential head injury
4. Rush to Unit B to assist with the complicated labor and delivery situation

**정답: 2**

## 해설

In crisis management, prioritize immediate life threats using ABCs. A ventilator-dependent patient without backup power faces imminent respiratory failure, while other situations (chest pain, labor, fall) are critical but allow brief delay for assessment or delegation.

Priority Setting in a Multi-Crisis Emergency

When a severe weather emergency causes power outages and staffing shortages, the charge nurse must apply a clinical triage framework that differs from standard mass casualty triage. In a hospital setting where resources are suddenly limited, the priority shifts to identifying which patient will experience the most immediate, irreversible harm without intervention. This requires assessing each situation through the lens of physiological stability and resource dependency.

Analysis of the Clinical Scenarios

The charge nurse is simultaneously presented with four critical patients. To determine the highest priority, a rapid assessment of each patient's immediate threat to life must be conducted, with special consideration given to the impact of the power outage.

| Option | Clinical Situation | Immediate Threat & Resource Dependency |
| --- | --- | --- |
| 1 | Chest pain with abnormal ECG changes | High risk for acute myocardial infarction. Requires continuous monitoring and possible intervention, but the patient currently has a pulse and is breathing spontaneously. |
| 2 | Ventilator-dependent patient | Apnea or severe respiratory failure. This patient's life is directly and immediately dependent on a machine that requires electricity. A power outage creates an imminent, life-threatening emergency within minutes. |
| 3 | Patient fall with potential head injury | Risk for increased intracranial pressure or intracranial hemorrhage. Requires rapid neurological assessment, but the patient is conscious and breathing. |
| 4 | Complicated labor and delivery | Risk to both mother and fetus. This is a high-acuity situation, but the immediate threat is not as universally time-critical in seconds-to-minutes as a loss of ventilatory support. |

Application of Resilience and Infrastructure Principles

The correct prioritization is to immediately ensure backup ventilation for the ventilator-dependent patient in Unit A. This decision is directly supported by the concept of slack in infrastructure, which identifies electricity supply as a fundamental resource for intensive care. The study by Marczyk et al. (2023) expands the view of hospital resilience beyond just beds and staff to include critical infrastructures like electricity supply and oxygen supply [2]. When a power outage occurs, the "slack" or redundancy in the electrical system has been exhausted. For a ventilator-dependent patient, this is not a potential future crisis; it is an active, ongoing catastrophe. The patient's physiological stability is entirely externally maintained. Without immediate manual resuscitation with a bag-valve-mask device connected to an oxygen source, the patient will suffer irreversible hypoxic brain injury and death within a very short timeframe.

The other scenarios, while critical, represent situations where the patient currently has a degree of physiological reserve. The patient with chest pain has a functioning cardiovascular system that is under threat but not yet collapsed. The patient who fell has a potential injury that requires assessment but is currently maintaining their airway and breathing. The laboring patient is in a dynamic process where the most critical moment (e.g., shoulder dystocia, cord prolapse) may not be occurring at this exact second. The trauma care guidelines emphasize strengthening the organization and planning for care to lower mortality . In this moment of organizational chaos caused by the weather emergency, the charge nurse's planning must center on the patient whose life is most immediately and mechanically threatened by the specific nature of the disaster: the loss of power. The principle of resilience management dictates that when a critical infrastructure fails, the first action is to manually compensate for that failure at the point of greatest immediate risk [2].References (research sources)

Clinical Practice Guide: Prioritizing Care During a Hospital Power Outage

Situation Overview

A severe weather emergency has caused a power outage and staffing shortages, presenting the charge nurse with multiple simultaneous critical situations. The immediate priority is to prevent irreversible patient harm by identifying the most resource-dependent, physiologically unstable patient.

Rapid Triage Framework

In a resource-limited internal disaster, standard mass casualty triage (e.g., START) is replaced by a focus on **resource dependency and physiological reserve**. The key question is: "Which patient will die or suffer irreversible harm the fastest without immediate intervention?"

- **Highest Priority:** Patients whose life is directly sustained by a now-compromised resource (e.g., ventilator, critical IV vasopressors).

- **Secondary Priority:** Patients with a time-sensitive but not immediately fatal condition (e.g., acute MI, active hemorrhage, acute neurological change).

- **Lower Priority:** Patients who are stable or whose condition has a longer window for intervention without immediate risk of death.

Action Steps for the Charge Nurse

- **Immediate Life-Saving Intervention:** Proceed directly to the ventilator-dependent patient in Unit A. The goal is to establish backup ventilation (e.g., manual bag-valve-mask ventilation, emergency backup power for the ventilator) within minutes to prevent hypoxic brain injury or death.

- **Simultaneous Delegation:** While responding to Unit A, use a communication device to delegate tasks:

- Direct the most clinically competent available nurse or rapid response team to Unit D (chest pain with abnormal ECG) to initiate acute coronary syndrome protocol and continuous monitoring.

- Assign another available staff member to Unit C (patient fall) to conduct a focused neurological assessment, maintain spinal precautions, and report back.

- Instruct the labor and delivery team in Unit B to continue managing the complicated delivery using emergency backup systems and to call for additional support if the situation deteriorates.

- **Activate Emergency Protocols:** Ensure the hospital incident command system is activated. Request additional emergency power sources, manual ventilation equipment, and personnel from the command center.

- **Reassess and Reprioritize:** Once the immediate threat to the ventilator-dependent patient is stabilized, rapidly reassess all other critical patients and redistribute resources based on the evolving clinical picture.

Clinical Reasoning Rationale

A patient with chest pain and ECG changes (Unit D) has a potentially lethal condition but currently has a pulse and spontaneous respirations, offering a brief window for intervention. A patient with a fall (Unit C) requires evaluation but is not at immediate risk of death. A complicated labor (Unit B) is critical, but maternal-fetal reserves provide more time than the seconds-to-minutes window of an apneic patient. The ventilator-dependent patient (Unit A) faces **imminent respiratory arrest** without a functioning machine, making this the highest priority for the charge nurse's direct intervention.

## 핵심 개념

- **Clinical Triage in Resource-Limited Settings** — A prioritization framework used during internal hospital disasters (like power outages) that focuses on preventing the most immediate, irreversible harm by assessing physiological stability and resource dependency, differing from standard mass casualty triage.
- **Ventilator-Dependent Patient** — A patient who relies on a mechanical ventilator to maintain adequate ventilation and oxygenation; a loss of power creates an immediate life-threatening emergency due to apnea or severe respiratory failure.
- **Resource Dependency** — The degree to which a patient's survival is immediately contingent on a specific, limited resource, such as electricity for a mechanical ventilator, which becomes a critical factor in priority setting during a power outage.
