A 68-year-old patient is admitted to the emergency department with sudden onset of right-sided weakness, slurred speech, and confusion that began 2 hours ago. The patient's vital signs are: BP 180/110 mmHg, HR 88 bpm, RR 20/min, Temperature 98.6°F (37°C). What is the nurse's highest priority action?

해설
Airway assessment is the highest priority per ABC approach, as stroke patients are at risk for airway compromise due to altered consciousness and impaired reflexes. Other actions like blood pressure management, neurological assessment, and CT scan are secondary until airway and breathing are secured.

Core Nursing Explanation Key Concept Analysis: This question tests the application of the ABC (Airway, Breathing, Circulation) priority framework in a suspected acute stroke patient. The patient presents with classic signs of an acute ischemic stroke (sudden right-sided weakness, slurred speech, confusion) within the critical 2-hour window. While all actions listed are important, the nurse must first address potential threats to life. A key principle in emergency nursing is that Key Point! assessment and management of the patient's own physiological stability (ABCs) always take precedence over diagnostic procedures or disease-specific treatments.

Answer Rationale: The correct answer is to Ensure airway patency and assess breathing adequacy. The patient's confusion and slurred speech indicate possible dysphagia (difficulty swallowing) and a decreased level of consciousness, which significantly increase the risk for aspiration and airway obstruction. A compromised airway leads to hypoxia, which can cause further, irreversible damage to the already vulnerable brain tissue. Therefore, securing the airway is the unquestionable first priority.

Distractor Analysis:
Watch out for confusion! Option ① (Administer antihypertensive medication) is incorrect because in acute ischemic stroke, aggressive blood pressure reduction is contraindicated. A degree of hypertension is often a compensatory mechanism to maintain cerebral perfusion pressure. Rapid lowering can worsen the stroke by reducing blood flow to the ischemic penumbra.
Option ② (Obtain a complete neurological assessment) is a critical and urgent action but is secondary to ensuring the patient can breathe. A detailed assessment cannot be performed effectively on a hypoxic patient.
Option ④ (Prepare for immediate CT scan) is also a time-sensitive and essential step to differentiate between ischemic and hemorrhagic stroke, which dictates treatment (e.g., thrombolytics). However, the patient must be physiologically stable enough to be transported and undergo the scan. The ABCs are assessed and managed first.

Related Concepts: This scenario integrates emergency response, stroke pathophysiology, and the nursing process. The ABC approach is the universal standard for initial assessment in any emergency. For stroke care, the "Time is Brain" concept emphasizes rapid intervention, but it must be executed within the framework of patient safety, starting with the fundamentals of life support. Concept Summary
ConceptDescriptionApplication in This Case
ABC PriorityAirway, Breathing, Circulation. The foundational sequence for all emergency assessments.Airway is assessed first due to risk of aspiration from neurological deficits.
Acute Ischemic StrokeSudden loss of blood flow to part of the brain, causing neurological deficits.Manifests as sudden unilateral weakness, speech problems, and confusion.
"Time is Brain"Concept that faster treatment leads to better outcomes by saving brain tissue.Drives urgency for CT scan and potential thrombolytics, but after ABCs are secure.
Blood Pressure Management in StrokeHypertension is often not treated aggressively initially unless extreme or in hemorrhagic stroke.BP of 180/110 mmHg in this scenario would not be immediately lowered with medication.

Side-by-Side Comparison!
Priority ActionWhen It's CorrectWhen It's Not the First Priority
Airway/Breathing (ABCs)In any patient with altered mental status, trauma, respiratory distress, or risk of aspiration.Rarely incorrect as a first step; it's the universal standard.
Neurological Assessment (e.g., NIHSS)Once patient is stable (ABCs secured), to establish a baseline and guide treatment.When the patient is actively choking, hypoxic, or in respiratory arrest.
Prepare for Diagnostic Test (CT Scan)After initial stabilization, as the next critical step to determine stroke type.If the patient is unstable for transport or requires immediate life-saving intervention.
Administer Disease-Specific MedicationAfter diagnosis is confirmed (e.g., tPA for ischemic stroke) and contraindications are ruled out.Before ensuring patient stability or confirming the diagnosis (e.g., giving tPA for a hemorrhage would be fatal).

Anatomy, Physiology & Pharmacology Points
  • Pathophysiology: In an ischemic stroke, a clot blocks a cerebral artery. The surrounding "penumbra" is brain tissue at risk of infarction. Maintaining adequate cerebral perfusion pressure (CPP) is crucial to salvage this tissue. A sudden drop in BP can reduce CPP, extending the infarct.
  • Airway Risk: Strokes affecting the brainstem or cortical areas controlling swallowing and consciousness impair the gag reflex and cough, leading to silent aspiration.
  • Pharmacology Caution: Antihypertensives like labetalol or nicardipine may be used later in a controlled manner, but guidelines typically advise against treatment unless BP is > 220/120 mmHg for ischemic stroke or there are other complications.

Memory Tips
  • ABCs First, Always!: Remember the mnemonic: "Always Before Considering anything else."
  • Stroke BP Mnemonic: "Don't Drop the Pressure in Ischemic Stroke!" Think of the brain needing that higher pressure to push blood past the clot.
  • Link Symptoms to Risk: "Slurred Speech + Confusion = Swallowing Danger." This directly connects the neurological exam finding to the priority nursing problem (risk for aspiration).

High-Frequency NCLEX Topics The NCLEX-RN loves testing priority-setting, especially in emergency scenarios. The ABC framework is one of the most tested concepts. Stroke management is a high-yield topic, often combined with questions on tPA administration, side effects (e.g., bleeding), and post-stroke care. Always ask yourself: "Is there an airway or breathing problem?" before selecting any other intervention.

Watch Out for Question Variations!
  • Shift from Symptom to Intervention: The question might ask: "The nurse notes the stroke patient has gurgling sounds on respiration. What is the priority action?" (Answer: Suction the airway).
  • Shift from Acute to Post-Acute: "Two days post-stroke, the patient's BP is 170/100. What is the nurse's best action?" (Answer: Monitor and report; gradual reduction may now be indicated per protocol, but not immediate).
  • Including a Time Factor: "The patient arrived 1 hour ago. The CT scan shows an ischemic stroke. What is the priority before administering tPA?" (Answer: Ensure no active bleeding or other contraindications exist; but initial ABCs would have already been done).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in the ED. EMS brings in Mr. Johnson, a 68-year-old male found by his wife slumped in his chair, unable to move his right arm and leg, and making incomprehensible sounds. He appears drowsy and is making wet, gurgling sounds with each breath.

Nursing Intervention Strategy:
  1. Immediate Assessment (ABCs): Upon arrival, you immediately perform a rapid assessment. You listen for breath sounds (gurgling indicates secretions in the airway), look for chest rise, and check the pulse. You position the patient in a lateral recumbent position (recovery position) if possible to protect the airway and use suction to clear secretions.
  2. Stabilize & Monitor: Apply oxygen via nasal cannula if needed, establish IV access, and connect to cardiac and pulse oximetry monitors. Obtain a STAT blood glucose check to rule out hypoglycemia (a stroke mimic).
  3. Focused Neurological Assessment: Once the airway is clear and breathing is adequate, you quickly perform a NIH Stroke Scale (NIHSS) assessment to quantify the deficit and provide a baseline. You also note the precise time of symptom onset (a "last known well" time).
  4. Collaborate & Prepare: Alert the stroke team and prepare the patient for the non-contrast head CT scan. You ensure all necessary labs are drawn (including coagulation studies for potential thrombolytics). You continue to monitor neurological status for any deterioration.
Patient Safety and Precautions:
  • Nothing by Mouth (NPO): The patient is kept NPO until a formal swallowing assessment is performed by a speech-language pathologist to prevent aspiration.
  • BP Management: Do not treat the elevated BP unless ordered specifically per stroke protocol. Continuously monitor for extreme hypertension or signs of increased intracranial pressure (ICP).
  • Safe Handling: Due to weakness, use proper lifting techniques and assist the patient with movement to prevent falls.

Nursing Procedure & Medication Flow Procedure: Rapid Airway Assessment & Suctioning 1. Assess: Look, Listen, Feel. Look for cyanosis, listen for stridor, gurgling, or absent breath sounds, feel for air movement. 2. Position: If no spinal injury is suspected, turn head to side or place in lateral position. 3. Suction: Use a Yankauer or catheter suction to clear the oropharynx. Limit suctioning to 10-15 seconds to prevent hypoxia. 4. Re-assess: After suctioning, reassess airway patency and breathing effectiveness.

Medication: Thrombolytics (e.g., Alteplase/tPA) - What Comes Before? Before administration, the nurse's role is critical in screening: - Confirm ischemic stroke on CT. - Verify time of symptom onset is within the treatment window (typically < 4.5 hours). - Check for absolute contraindications: active bleeding, recent surgery, history of intracranial hemorrhage, elevated PT/INR, platelets < 100,000. - Ensure two IV lines are established (one for tPA, one for other medications). - Have emergency medications (e.g., to treat bleeding) readily available.

A Word from Your Senior Nurse "In the chaos of an emergency, your training kicks in. Remembering your ABCs is like muscle memory. With stroke patients, we are racing against the clock, but we can't run if the patient can't breathe. That moment of taking 30 seconds to suction a patient, see their oxygen saturation improve, and their color return is where nursing saves lives before the miracle drug is even considered. On the NCLEX, they are testing if you have this foundational safety mindset. In real life, this mindset lets you act confidently when every second counts."
