해설
Neurogenic shock is a life-threatening complication in acute T6 spinal cord injury, requiring immediate assessment and monitoring. Other options are important but secondary to stabilizing cardiovascular status.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing action for a patient with a new, acute Spinal Cord Injury (SCI) at the T6 level. The core theme is recognizing and managing the immediate, life-threatening complication of Neurogenic Shock. Neurogenic shock results from the loss of sympathetic nervous system tone below the level of injury, leading to vasodilation and unopposed parasympathetic (vagal) activity. The classic triad is Key Point!Hypotension, Bradycardia, and Warm, dry skin (due to vasodilation). The patient's symptoms (bradycardia, hypotension, dizziness, nausea) are classic signs of this condition, which can rapidly lead to inadequate perfusion and organ damage if not addressed.
Answer Rationale: The highest priority is Assessment for Neurogenic Shock and Initiation of Continuous Cardiac Monitoring. The nursing process always begins with assessment. Before any intervention, the nurse must confirm the diagnosis and establish a baseline for ongoing evaluation. Continuous cardiac monitoring is essential because the patient's hemodynamic status (heart rate, blood pressure) is unstable and requires constant surveillance. This action directly addresses the ABCs (Airway, Breathing, Circulation) by prioritizing the assessment and stabilization of Circulation, which is compromised.
Distractor Analysis:
Option 1 (Administer atropine): While atropine is used to treat symptomatic bradycardia, administering it immediately without a comprehensive assessment and specific physician order for this context is not the first priority. The bradycardia is part of a larger syndrome (neurogenic shock), and treatment often involves addressing hypotension first with fluids and vasopressors. The nurse must assess and monitor first.
Option 2 (Insert NG tube): Preventing aspiration is important, especially if the patient has a paralytic ileus (common in SCI), which can cause nausea and vomiting. However, this is not the highest priority when the patient's circulatory status is unstable and life-threatening. This is a secondary intervention.
Option 3 (Apply SCDs): Preventing Deep Vein Thrombosis (DVT) is a critical standard of care for immobilized spinal cord injury patients and should be initiated promptly. However, in the acute phase (2 hours post-injury), stabilizing the patient's cardiovascular system from neurogenic shock takes precedence over this prophylactic measure. SCDs can be applied after the immediate threat to circulation is being managed.
Related Concepts: It is crucial to distinguish Watch out for confusion!Neurogenic Shock from Spinal Shock. Spinal shock refers to the temporary loss of all neurologic function (motor, sensory, reflexes) below the level of injury, which can last days to weeks. Neurogenic shock is a cardiovascular phenomenon of hypotension and bradycardia. A patient can be in both states simultaneously. Also, differentiate neurogenic shock (warm, dry skin, bradycardia) from Hypovolemic Shock (cool, clammy skin, tachycardia), which is common in trauma from bleeding.

Anatomy, Physiology & Pharmacology Points
Anatomy: The sympathetic nervous system fibers exit the spinal cord from T1 to L2. An injury at T6 or above disrupts a major portion of this outflow, leading to unopposed parasympathetic (vagus nerve) influence on the heart, causing bradycardia.
Physiology: Sympathetic tone maintains vascular tone (vasoconstriction). Loss of tone causes massive vasodilation in the periphery, leading to pooling of blood, decreased venous return, and hypotension.
Pharmacology: First-line treatment for neurogenic shock includes IV fluids (crystalloids) to increase preload, and vasopressors (e.g., Norepinephrine, Phenylephrine) to induce vasoconstriction. Atropine may be used for severe bradycardia.
Memory Tips
Neurogenic Shock = "Warm and Slow": Warm skin (vasodilation) + Slow heart rate (bradycardia). The opposite of most other shocks.
Injury Level Mnemonic: "T6 is the Mix" – Injuries at T6 and above mix up the autonomic system, causing neurogenic shock. Injuries below T6 typically spare enough sympathetic outflow to prevent it.
Priority Order: Remember ABC (Airway, Breathing, Circulation). This patient's breathing may be compromised if the injury is high cervical, but the question focuses on the presented circulatory symptoms. Always assess the threat to life first.
High-Frequency NCLEX Topics
Spinal Cord Injury management is a high-yield NCLEX topic. You must know:
The differences between Neurogenic Shock (acute) and Autonomic Dysreflexia (chronic).
Priority interventions for each.
The level of injury (Cervical vs. Thoracic) and its implications for respiratory function.
Complications of immobility (DVT, pressure ulcers, contractures) and their prevention.
Watch Out for Question Variations!
Symptom Identification: "A client with a T4 spinal cord injury has a blood pressure of 150/98 mmHg, a severe headache, and diaphoresis. What complication should the nurse suspect?" (Answer: Autonomic Dysreflexia).
Priority Intervention: "The nurse is caring for a client in neurogenic shock. Which prescribed intervention should be implemented first?" (Answer: Initiate continuous hemodynamic monitoring OR administer IV fluid bolus).
Patient Positioning: "What is the best position for a client with neurogenic shock?" (Answer: Supine, possibly with legs elevated to promote venous return, unless contraindicated by other injuries).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse receiving a report in the Emergency Department. Mr. Jones, a 22-year-old, was in an MVC and has a confirmed T6 fracture with spinal cord involvement. He is on a backboard with a cervical collar. Two hours post-arrival, you note his heart rate is 52, BP 88/50, and he says, "I feel really dizzy and like I might throw up." His skin is warm to the touch on his arms and chest.
Nursing Intervention Strategy:
Immediate Assessment (Priority): Perform a focused assessment confirming neurogenic shock. Check bilateral breath sounds (high thoracic injuries can impair respiratory muscle function). Perform a full neurologic check (motor, sensory, reflexes) to establish a baseline for spinal shock. Palpate peripheral pulses and assess skin temperature and color.
Stabilize Circulation: Initiate continuous cardiac monitoring and pulse oximetry. Obtain large-bore IV access if not already present. Anticipate and prepare for:
Administration of an isotonic IV fluid bolus (e.g., Normal Saline or Lactated Ringer's) as ordered.
Preparation of vasopressor infusion (e.g., norepinephrine) as the next step if fluids alone are insufficient.
Administration of atropine for symptomatic bradycardia per protocol or order.
Comprehensive Care: Once hemodynamics are being actively managed, proceed with other critical interventions:
Insert a urinary catheter (Foley) to monitor output and prevent bladder distension (a trigger for autonomic dysreflexia).
Insert a nasogastric tube for decompression to prevent vomiting and aspiration from paralytic ileus.
Apply sequential compression devices (SCDs) for DVT prophylaxis.
Implement strict log-rolling for turns and meticulous skin care to prevent pressure ulcers.
Patient Safety and Precautions:
Hypotension Caution: Avoid sudden position changes. Raise the head of the bed slowly if needed, monitoring for increased dizziness.
Medication Safety: Vasopressors must be administered via a central line or a large peripheral IV with close monitoring for infiltration, which can cause severe tissue necrosis.
Monitoring: Strict intake and output (I&O) monitoring is essential. Over-aggressive fluid resuscitation in neurogenic shock can lead to pulmonary edema, as the heart may not be failing but the vasculature is dilated.
Assess & Monitor: Connect to cardiac monitor. Document rhythm, HR, BP, SpO2 every 5-15 minutes initially.
Secure Access: Ensure patent IV access (18-gauge or larger).
Fluid Resuscitation: Administer 500-1000 mL isotonic crystalloid bolus as ordered. Reassess BP and HR after each bolus.
Vasopressor Initiation: If hypotension persists, initiate vasopressor drip via an infusion pump. Titrate to maintain target BP (e.g., MAP > 65 mmHg).
Ongoing Care: Once stable, implement DVT prophylaxis, bowel/bladder program, and skin integrity protocols.
A Word from Your Senior Nurse
"Remember, in trauma and spinal cord injuries, your brain needs to run through two checklists simultaneously: the immediate life threats (ABCs, bleeding, shock) and the unique complications of the injury (neurogenic shock, autonomic dysreflexia, respiratory compromise). This patient's bradycardia and hypotension aren't from blood loss; they're from a 'disconnected' nervous system. Your priority is to be the detective who puts the clues together (T6 injury + bradycardia + hypotension = neurogenic shock) and then be the first responder who acts to support their body until medical treatments take effect. Assessment always comes first—you can't fix what you haven't identified. This critical thinking is what the NCLEX tests and what will save your patient's life."
Neurogenic Shock — A distributive shock caused by the loss of sympathetic nervous system tone, typically from a spinal cord injury above T6, leading to vasodilation, hypotension, and bradycardia.
Spinal Shock — A temporary state of flaccid paralysis, areflexia, and loss of sensation below the level of a spinal cord injury, which may last from days to several weeks.
Autonomic Dysreflexia — A life-threatening hypertensive emergency in patients with spinal cord injuries above T6, triggered by a noxious stimulus below the injury level, characterized by severe headache, hypertension, and diaphoresis.
Bradycardia — A heart rate less than 60 beats per minute. In neurogenic shock, it results from unopposed parasympathetic (vagal) influence due to loss of sympathetic tone.
Sequential Compression Devices — Mechanical devices used for DVT prophylaxis that intermittently inflate sleeves around the legs to promote venous return and prevent blood clot formation.
