A nurse is caring for a patient with a suspected cerebral aneurysm who is scheduled for diagnostic testing. Which nursing intervention is the highest priority to prevent aneurysm rupture?
A 45-year-old patient presents to the emergency department with a sudden onset of severe headache, described as "the worst headache of my life." The patient also reports photophobia, neck stiffness, and nausea. Vital signs are: BP 180/110 mmHg, HR 95 bpm, RR 22/min, Temperature 99.2°F (37.3°C). A cerebral aneurysm is suspected, and the patient is awaiting CT angiography.

해설
Maintaining strict blood pressure control and avoiding ICP-increasing activities is the priority to prevent aneurysm rupture by reducing wall tension. Other options address symptoms or anxiety but do not directly prevent rupture.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing intervention for a patient with a suspected cerebral aneurysm to prevent rupture. The core pathophysiology is that an aneurysm is a weakened, ballooned area in a cerebral artery wall. The primary risk is rupture, which leads to a subarachnoid hemorrhage (SAH). The force that can cause rupture is related to the pressure within the vessel and the tension on the aneurysm wall. Therefore, the highest priority is to minimize factors that increase this pressure and tension.
Answer Rationale: Key Point! Option ④ is correct because it directly addresses the two most critical modifiable risk factors for aneurysm rupture: elevated blood pressure and increased intracranial pressure (ICP). Strict BP control (often with IV medications like nicardipine or labetalol) reduces the hemodynamic stress on the aneurysm wall. Avoiding activities that increase ICP (like straining, coughing, vomiting, or isometric exercises) prevents sudden spikes in pressure that could trigger rupture. This is the definitive, preventative action.
Distractor Analysis:
Watch out for confusion! Option ①: While pain management is important, administering analgesics "as needed" is not the priority. The nurse must first ensure that any medication given does not mask neurological deterioration or cause hypotension. More importantly, the priority action is to control the environment and BP to prevent the need for pain relief due to rupture.
Option ②: Reducing anxiety is a supportive measure, but encouraging deep breathing can be dangerous. If done forcefully, it can involve Valsalva-like maneuvers, temporarily increasing intrathoracic and intracranial pressure, which is contraindicated.
Option ③: The Trendelenburg position (head down, feet up) is absolutely contraindicated. This position increases venous return to the head, significantly raising intracranial pressure, which could directly precipitate aneurysm rupture.
Related Concepts: The classic presentation of "the worst headache of my life" with photophobia and nuchal rigidity (neck stiffness) is hallmark for subarachnoid hemorrhage. Nursing care focuses on neurological assessment (using tools like the Glasgow Coma Scale (GCS)), maintaining a quiet, dark environment to minimize stimulation, and preparing for potential emergency interventions like surgical clipping or endovascular coiling.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse in the ED for Mr. Johnson, a 45-year-old with the described symptoms. The room is kept dimly lit due to his photophobia. He is restless and in severe pain.
Nursing Intervention Strategy:
1Assessment & MonitoringPerform frequent, focused neurological assessments (GCS, pupil check, motor strength). Monitor BP continuously via arterial line if available. Assess for signs of re-bleeding or worsening: sudden severe headache, decreased LOC, new neurological deficits.
2Environment & ActivityMaintain strict bed rest with the head of bed elevated to 30 degrees. This promotes venous drainage from the brain, lowering ICP. Enforce complete bed rest—no turning without assistance, no pushing up in bed. Provide a bedside commode to avoid the strain of using a bedpan if possible.
3Medication & Symptom ManagementAdminister antihypertensives as ordered to keep systolic BP within a strict target range (e.g., 120-140 mmHg). Administer stool softeners to prevent constipation and straining. For headache, administer prescribed analgesics (often acetaminophen or codeine derivatives—avoid NSAIDs due to antiplatelet effects) and assess effect.
4Patient & Family EducationExplain all activities and restrictions in simple terms. "Mr. Johnson, we need to keep you very still and calm to protect the blood vessel in your brain. Please try not to cough or bear down. Use the call button for everything."
Patient Safety and Precautions: Never leave the patient unattended on a bedpan. Avoid any sudden, jarring movements. Suction only if absolutely necessary and with extreme caution. Be vigilant for seizures, which are a common complication post-rupture.
Nursing Procedure & Medication FlowBlood Pressure Management Protocol:
1. Connect to continuous cardiac and BP monitoring.
2. Titrate IV antihypertensive drip (e.g., Nicardipine) per protocol to maintain goal BP.
3. Avoid rapid reductions in BP which can cause cerebral ischemia.
4. Monitor for side effects: reflex tachycardia, hypotension, headache.Preventing ICP Spikes:
- Cluster nursing care to minimize stimulation.
- Pre-medicate before potentially painful procedures.
- Teach the patient to exhale during turning or movement.
A Word from Your Senior Nurse
"In neuro nursing, we are guardians of pressure—both blood pressure and intracranial pressure. With an aneurysm, think of it as a weak spot on a balloon. Your job is to keep the air pressure (BP) steady and avoid squeezing the balloon (increasing ICP). That 'worst headache' history should set off all your alarm bells. Your calm, controlled actions and vigilant monitoring are what stand between this patient and a catastrophic bleed. On the NCLEX, they love to test your ability to sift through 'good' interventions to find the one that is safest and most preventative—which is almost always controlling physiological parameters to prevent deterioration."
Cerebral Aneurysm — A localized, abnormal dilation or ballooning of a cerebral artery wall, creating a weak spot prone to rupture.
Subarachnoid Hemorrhage — Bleeding into the subarachnoid space, often caused by a ruptured cerebral aneurysm, presenting with thunderclap headache, nuchal rigidity, and photophobia.
Intracranial Pressure — The pressure exerted by the cerebrospinal fluid, brain tissue, and blood within the rigid skull. Elevated ICP is a critical concern in neurological injuries and can precipitate aneurysm rupture.
Glasgow Coma Scale — A standardized neurological assessment tool that evaluates eye opening, verbal response, and motor response to determine a patient's level of consciousness. Scores range from 3 (deep coma) to 15 (fully alert).
Trendelenburg Position — A position where the patient's body is laid flat on the back with the feet higher than the head. It is contraindicated in suspected intracranial hypertension as it increases cerebral venous pressure and ICP.
