4Sudden onset of severe headache with projectile vomiting and altered level of consciousness✓ 정답
해설
Sudden severe headache with projectile vomiting and altered LOC is critical for increased ICP, needing urgent intervention to prevent herniation. Other findings are stroke-related but less emergent.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to prioritize neurological assessment findings in a patient with a suspected hemorrhagic stroke. The core theme is recognizing the signs of rapidly increasing Intracranial Pressure (ICP) and impending Brain herniation, which are life-threatening emergencies requiring immediate intervention. In hemorrhagic stroke, bleeding into the brain parenchyma or subarachnoid space causes mass effect, leading to increased ICP.
Answer Rationale: Key Point! Option ④ describes the classic triad of symptoms indicating a catastrophic rise in ICP: Sudden, severe "thunderclap" headache (from bleeding and meningeal irritation), Projectile vomiting (from pressure on the brainstem's vomiting center), and Altered level of consciousness (LOC) (from direct pressure on the reticular activating system). This combination signals an immediate risk of brain herniation and death, demanding urgent measures like hyperosmolar therapy (e.g., mannitol), possible surgical evacuation, or securing the airway.
Distractor Analysis:
Option ① (GCS decreased from 14 to 12): A decline in the Glasgow Coma Scale (GCS) is significant and requires monitoring, but a change from 14 to 12 indicates mild deterioration. The patient remains in a relatively alert state. While it should be reported, it is not as immediately life-threatening as the signs in option ④.
Option ② (BP 180/100 mmHg): Watch out for confusion! Elevated blood pressure is common in acute stroke (a compensatory mechanism to maintain cerebral perfusion pressure). While it needs to be managed carefully to prevent re-bleeding or extension of the hemorrhage, a rapid, drastic lowering of BP can be dangerous. A BP of 180/100 in this context is an important finding but is not the most critical indicator of an imminent, catastrophic event like herniation.
Option ③ (Left-sided facial droop): This is a classic focal neurological deficit indicating a stroke, likely involving the facial nerve pathways. It is a key diagnostic finding for stroke identification (think FAST - Face, Arms, Speech, Time) but, by itself, is a static deficit rather than a sign of rapid, progressive neurological decline.
Related Concepts: The priority in neurological emergencies follows the ABCs (Airway, Breathing, Circulation) with a neuro twist: protect the airway (which is compromised with altered LOC), ensure adequate ventilation, and manage circulation to optimize cerebral perfusion. Signs of herniation (e.g., Cushing's triad - bradycardia, hypertension, irregular respirations; unilateral pupil dilation) trump focal deficits in terms of urgency.
Concept Summary
Concept
Description
Clinical Significance
Hemorrhagic Stroke
Bleeding into brain tissue (intracerebral) or spaces (subarachnoid).
Mass effect leads to rapid Increased Intracranial Pressure (ICP).
Increased ICP
Pressure inside the skull rises due to bleeding, edema, or tumor.
Can compress brain tissue and blood vessels, leading to ischemia and herniation.
Brain Herniation
Displacement of brain tissue from one compartment to another.
A fatal complication. Signs include altered LOC, vomiting, pupillary changes, posturing.
Glasgow Coma Scale (GCS)
Objective tool to assess LOC (Eye, Verbal, Motor responses).
Scores range 3-15. A decreasing trend indicates neurological deterioration.

Anatomy, Physiology & Pharmacology Points
Monro-Kellie Doctrine: The skull is a rigid box. An increase in the volume of one component (blood, brain, CSF) must be compensated by a decrease in another, or ICP will rise. Bleeding from a hemorrhagic stroke adds volume, causing pressure.
Brainstem Compression: The vomiting center is located in the medulla. Increased pressure on the brainstem causes projectile vomiting. Pressure on the Reticular Activating System (RAS) alters consciousness.
Pharmacology: First-line agents for lowering ICP include Mannitol (an osmotic diuretic that draws fluid from brain tissue into the vasculature) and Hypertonic saline.
Memory Tips
H for Herniation Horror: Remember the deadly trio: Headache (severe), Hurl (vomiting), Hazy (altered LOC).
FAST vs. SLOW: FAST (Face, Arm, Speech, Time) helps identify a stroke. SLOW deterioration with headache/vomiting points to Swelling and Lethal Overpressure Warning (increased ICP).
High-Frequency NCLEX Topics
NCLEX loves testing prioritization and recognition of medical emergencies. "Which finding is most critical?" or "Which patient should the nurse see first?" questions often hinge on identifying signs of airway compromise, shock, or neurological catastrophe (like increased ICP). Know the red flags that trump other important but less urgent findings.
Watch Out for Question Variations!
Shift from Assessment to Intervention: "The nurse notes sudden projectile vomiting and a decreased LOC in a stroke patient. What is the nurse's priority action?" (Answer: Ensure a patent airway and call for immediate help).
Pharmacology Integration: "A patient with signs of increased ICP is prescribed mannitol. For which finding should the nurse monitor most closely?" (Answer: Watch out for confusion! While urine output is important, the most critical is a decrease in serum sodium and potassium levels due to fluid shifts and diuresis, or signs of worsening renal function).
Differentiating Stroke Types: A question may give a scenario and ask, "Which finding suggests a hemorrhagic rather than an ischemic stroke?" (Answer: Sudden, severe headache with vomiting and decreased LOC is more classic for hemorrhage).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 65, was admitted one hour ago with left-sided weakness and a suspected stroke. His initial GCS was 14, and he had a left facial droop. He is on telemetry and hourly neuro checks. During your 2-hour assessment, he groans when you call his name (previously he was oriented), complains of "the worst headache of my life," and then without warning, vomits forcefully across the bed.
Nursing Intervention Strategy:
Immediate Action (Seconds): Call for help using the call light or shout for assistance. Turn the patient to his side (recovery position) to prevent aspiration from vomiting. Assess airway patency.
Rapid Assessment (1 Minute): Perform a quick neurological assessment: Check pupil size and reaction (looking for asymmetry or dilation), assess GCS (note the score), check motor response (note any posturing - decorticate or decerebrate).
Communication & Escalation (2 Minutes): Inform the charge nurse and the primary provider/rapid response team STAT. Clearly report: "Patient with suspected hemorrhagic stroke, now with altered LOC (GCS dropped from 14 to X), projectile vomiting, and severe headache. Airway is currently patent."
Prepare for Interventions: Anticipate and prepare for:
Transfer to ICU or for stat CT scan.
Administration of hyperosmolar agents (have IV access ready).
Possible intubation to protect the airway.
Patient Safety and Precautions:
Aspiration Risk: The #1 immediate danger with vomiting and decreased LOC is aspiration pneumonia. Positioning is key.
Blood Pressure Management: Do not aggressively lower BP without specific orders. The brain may be relying on higher pressure for perfusion. Target parameters are usually set by the neurologist.
Minimize Stimuli: Keep the head of the bed elevated to 30 degrees (unless contraindicated), maintain a quiet environment, and cluster care to avoid activities that increase ICP (e.g., vigorous suctioning, neck flexion).
Nursing Procedure & Medication FlowNeurological Assessment (Focused for ICP):
Level of Consciousness: Use AVPU (Alert, Voice, Pain, Unresponsive) or GCS. Document any change.
Pupils: Check size (mm), shape, equality, and reaction to light. A unilateral fixed and dilated pupil is a late sign of uncal herniation.
Motor Function: Check strength and movement in all extremities. Note any abnormal posturing.
Vital Signs: Monitor for Cushing's Triad: Hypertension (with widening pulse pressure), Bradycardia, and Irregular respirations. This is a late sign of severely increased ICP.
Mannitol Administration:
Action: Osmotic diuretic. Draws fluid from brain tissue into blood vessels, reducing cerebral edema.
Precautions: Administer via a filter needle and an IV pump. Monitor for:
Fluid and electrolyte imbalance (especially hyponatremia, hypokalemia).
Renal function (increased BUN/Cr).
Rebound increased ICP if infused too quickly or stopped abruptly.
A Word from Your Senior Nurse
In neuro nursing, you are the guardian of the "windows to the brain" - the pupils and the level of consciousness. A patient can go from talking to you to herniating in minutes. Trust your assessment. That "funny feeling" that something isn't right? That's your nursing intuition, built on knowledge. When you see that triad of headache, vomiting, and a change in alertness, your internal alarm bells should be screaming "ICP!" Don't wait for the next scheduled check. Act, assess, and advocate immediately. This vigilance saves lives and is the heart of what makes a great neuro nurse.
Intracranial Pressure — The pressure exerted by cerebrospinal fluid, blood, and brain tissue within the rigid skull. Normal is 5-15 mmHg.
Brain Herniation — A life-threatening condition where brain tissue is displaced from its normal compartment into another, often due to increased ICP, leading to brainstem compression and death.
Glasgow Coma Scale — A standardized neurological assessment tool that evaluates a patient's level of consciousness based on Eye, Verbal, and Motor responses. Scores range from 3 (deep coma) to 15 (fully alert).
Cushing's Triad — A classic but late sign of severely increased ICP: hypertension (with a widening pulse pressure), bradycardia, and irregular respirations.
Monro-Kellie Doctrine — The physiological principle stating that the cranial cavity is a fixed volume. An increase in one component (blood, brain, CSF) must be compensated by a decrease in another, or ICP will rise.
