## 문제

A 38-year-old patient with a ruptured cerebral aneurysm, presenting with sudden severe headache, photophobia, nuchal rigidity, and nausea, is admitted to the neurological intensive care unit. Which nursing intervention should be the highest priority?

A 45-year-old patient presents to the emergency department with sudden onset of severe headache described as "the worst headache of my life." CT scan reveals subarachnoid hemorrhage from a ruptured cerebral aneurysm. The patient is conscious but exhibits photophobia, nuchal rigidity, and nausea.

## 해설

A quiet, darkened environment minimizes stimulation to prevent rebleeding by reducing intracranial pressure. Other options, like position changes or aggressive pain management, could increase risk and are not the highest priority.

Clinical Context and Priority Setting

This patient presents with a classic triad of aneurysmal subarachnoid hemorrhage (aSAH): a sudden, severe "thunderclap" headache, photophobia, and nuchal rigidity. The underlying pathophysiology involves arterial blood escaping into the subarachnoid space under high pressure, which causes a sudden increase in intracranial pressure (ICP), diffuse meningeal irritation, and a profound sympathetic surge. In the hyperacute phase following aneurysm rupture, the primary goal of nursing care is to prevent rebleeding, a catastrophic complication carrying a case-fatality rate of approximately 40% [1]. Rebleeding is most likely to occur within the first 24 to 72 hours and is often triggered by factors that increase transmural pressure across the fragile aneurysm wall or sudden spikes in ICP.

Analysis of the Highest Priority Intervention

The correct answer is to maintain the patient in a quiet, darkened environment to reduce stimulation. This intervention directly targets the reduction of external stimuli that can trigger a sympathetic response, thereby minimizing fluctuations in blood pressure and cerebral blood flow. Photophobia and hyperacusis are clinical manifestations of meningeal irritation; exposure to bright light and noise exacerbates discomfort and can lead to agitation, Valsalva maneuvers, and transient hypertension. By controlling the environment, the nurse actively reduces the risk of rebleeding by keeping the patient's cerebral perfusion pressure as stable as possible. This aligns with the foundational principles of aSAH management derived from high-level evidence, which emphasizes strict hemodynamic control and avoidance of sudden pressure changes in the vulnerable period before the aneurysm is secured [1].

Why the Other Options Are of Lower Priority

- Encouraging frequent position changes to prevent complications of immobility is a standard nursing intervention for many critically ill patients, but it is contraindicated in the hyperacute phase of aSAH. Frequent turning, especially if the patient strains or if the head of the bed is lowered, can cause rapid ICP fluctuations and increase the risk of rebleeding. Immobility complications such as pressure injuries or deep vein thrombosis are secondary concerns that are addressed with prophylactic measures (e.g., sequential compression devices) once hemodynamic stability is achieved, not through active repositioning.

- Providing aggressive pain management with opioid analgesics is an important component of care, as pain and anxiety increase sympathetic tone and blood pressure. However, the method of delivery is critical. Aggressive bolus dosing can cause rapid vasodilation, hypotension, or respiratory depression with subsequent hypercapnia, all of which alter cerebral hemodynamics dangerously. Pain management must be titrated carefully and is a means to achieve the calm state described in the correct answer, not an independent first step that precedes environmental control. The non-pharmacological approach of reducing noxious stimuli is the foundational, safest, and immediate priority.

- Implementing active range of motion exercises to maintain muscle strength is absolutely contraindicated. Active movement requires muscle contraction, which can involve a Valsalva maneuver, directly increasing intrathoracic and intracranial pressure. Any form of exercise or physical exertion in a patient with an unsecured, ruptured aneurysm poses a direct and severe risk of inducing rebleeding. Passive range of motion, if performed, is done with extreme caution and only under specific orders, but active exercises are deferred until the aneurysm is definitively treated.

The core principle is that until the aneurysm is surgically clipped or endovascularly coiled, the overarching nursing priority is the prevention of rebleeding through meticulous control of the patient's internal and external environment to avoid any surge in ICP or blood pressure [1].References (research sources)

## 임상 시나리오

Clinical Scenario

A 38-year-old patient is admitted to the neurological intensive care unit with a ruptured cerebral aneurysm presenting with sudden severe headache, photophobia, nuchal rigidity, and nausea. The patient is in the hyperacute phase following aneurysmal subarachnoid hemorrhage (aSAH).

Nursing Priorities

- **Prevent Rebleeding:** The highest priority in the first 24-72 hours. Maintain a quiet, darkened environment to minimize sympathetic stimulation and blood pressure fluctuations.

- **Strict Bed Rest:** Keep the head of bed elevated to 30 degrees to promote venous drainage and reduce intracranial pressure (ICP). Avoid clustering care activities.

- **Hemodynamic Management:** Monitor blood pressure continuously via arterial line. Maintain systolic blood pressure within prescribed parameters (often

## 핵심 개념

- **Rebleeding** — A catastrophic complication after aneurysmal subarachnoid hemorrhage where the aneurysm ruptures again, carrying a case-fatality rate of approximately 40% and most likely occurring within the first 24 to 72 hours.
- **Nuchal rigidity** — Stiffness of the neck muscles caused by meningeal irritation from blood in the subarachnoid space, a classic sign of subarachnoid hemorrhage.
- **Transmural pressure** — The pressure gradient across the wall of a blood vessel; increases in this gradient can stress a fragile aneurysm wall and trigger rebleeding.
- **Sympathetic surge** — A massive release of catecholamines following aneurysm rupture that causes acute hypertension and increased myocardial workload, contributing to neurogenic stunned myocardium.
- **Valsalva maneuver** — Forced expiration against a closed glottis that increases intrathoracic pressure, venous pressure, and intracranial pressure, and can provoke rebleeding in patients with cerebral aneurysms.
