A nurse is caring for a 7-year-old child diagnosed with Reye's syndrome. Which nursing intervention should be the priority?

## 보기

1. Monitor neurological status and intracranial pressure closely **✔ 정답**
2. Administer aspirin for fever reduction
3. Encourage oral fluid intake to prevent dehydration
4. Provide high-protein diet to support liver function

**정답: 1**

## 해설

Monitoring neurological status and intracranial pressure is the priority for Reye's syndrome due to risk of cerebral edema. Other options are contraindicated (aspirin) or less urgent (fluids, diet).

Understanding Reye's Syndrome and the Priority Nursing Intervention

The correct answer is to monitor neurological status and intracranial pressure closely.

Reye's syndrome is an acute, life-threatening condition that primarily affects children and is characterized by encephalopathy and fatty degeneration of the liver. The pathophysiology involves mitochondrial dysfunction, which leads to a failure of the liver's metabolic functions and, critically, the development of cerebral edema. The progression of cerebral edema results in increased intracranial pressure (ICP), which is the direct cause of the neurological deterioration, coma, and potential death associated with this syndrome. Therefore, the most immediate threat to the patient's life is neurological compromise from rising ICP, making continuous neurological assessment and ICP management the absolute priority. While hepatic dysfunction is a core component of the disease, the neurological sequelae dictate the urgency of care.

Let's analyze why the other options are incorrect or lower priority:

1.  Administer aspirin for fever reduction: This is contraindicated. The use of aspirin during a viral illness, such as influenza or varicella, has a strong epidemiological link to the development of Reye's syndrome. Administering aspirin would not only fail to treat the underlying condition but could potentially worsen it. Fever management in this context would rely on non-pharmacological measures and non-aspirin antipyretics like acetaminophen, though the priority remains managing ICP.

2.  Encourage oral fluid intake to prevent dehydration: This is a low-priority and potentially dangerous intervention. A child with Reye's syndrome often presents with an altered level of consciousness, vomiting, and a risk of aspiration. Oral intake is typically contraindicated in the acute phase to prevent aspiration and because the patient's neurological status may necessitate airway protection. Fluid and electrolyte management are critical but are achieved through intravenous therapy, guided by strict intake and output monitoring and serum osmolality levels to manage cerebral edema.

3.  Provide a high-protein diet to support liver function: This is incorrect. The liver's metabolic failure in Reye's syndrome impairs its ability to process protein, leading to the accumulation of ammonia and other nitrogenous wastes, which contributes to hepatic encephalopathy. The standard nutritional support, once the patient is stabilized, involves providing adequate calories, often as a high-dextrose infusion, to prevent catabolism, while protein intake is initially restricted to minimize hyperammonemia.

From an NCLEX-RN perspective, this question tests your ability to apply the ABC (Airway, Breathing, Circulation) and safety frameworks. A compromised neurological status directly threatens the airway and breathing. The priority is to recognize that the most lethal progression of Reye's syndrome is brain herniation from uncontrolled ICP, making neurological monitoring the most critical nursing action.

Reye's Syndrome Priority CareNeurological Monitoring Over Hepatic Interventions
In Reye's syndrome, the primary pathophysiological threat is cerebral edema leading to increased intracranial pressure (ICP). Continuous neurological assessment and ICP management take absolute priority to prevent coma and death.

CautionAspirin is strictly contraindicated due to its epidemiological link to Reye's syndrome. Use non-aspirin antipyretics for fever management.

## 핵심 개념

- **Reye's Syndrome** — An acute, life-threatening condition in children characterized by encephalopathy and fatty liver degeneration, linked to aspirin use during viral illnesses.
- **Cerebral Edema** — Swelling of the brain caused by the accumulation of fluid, which is the primary cause of neurological deterioration in Reye's syndrome.
- **Intracranial Pressure (ICP)** — The pressure inside the skull; increased ICP from cerebral edema is the direct cause of coma and death in Reye's syndrome.
