A nurse is conducting a primary assessment of an elderly patient who arrives at the emergency department following a motor vehicle accident. Which assessment should the nurse prioritize first?

In emergency nursing, the primary assessment follows the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure). Airway and breathing assessment must be prioritized first as they are immediately life-threatening if compromised.

Core Nursing Explanation Key Concept Analysis: This question tests the fundamental principle of primary assessment in emergency and trauma nursing. The core concept is the systematic, prioritized approach to identifying and managing immediate life threats. The universally accepted framework for this is the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure). This sequence is not arbitrary; it is based on the physiological principle that an obstructed airway or inadequate breathing will lead to brain damage and death within minutes, making them the highest priority threats to life.

Answer Rationale: Key Point! The correct answer is to Establish airway patency and breathing adequacy. This aligns perfectly with the "A" (Airway) and "B" (Breathing) of the ABCDE approach. In any trauma or emergency situation, the nurse's first action must be to ensure the patient has a patent airway and is breathing effectively. A patient who is conscious and talking has a patent airway at that moment, but the nurse must continuously assess for potential compromise from swelling, secretions, or a decreasing level of consciousness. The patient's anxiety and restlessness could be signs of pain, but they could also be early indicators of hypoxia (inadequate oxygen) or shock, making the assessment of breathing even more critical.

Distractor Analysis: Watch out for confusion! Checking for neurological deficits (Option 1) corresponds to the "D" (Disability) in the ABCDE sequence. While crucial in a trauma assessment, it comes after ensuring the patient's airway, breathing, and circulation are adequate. A neurological change can be a sign of deteriorating circulation or oxygenation to the brain.
Assessing for internal bleeding (Option 2) falls under "C" (Circulation). Internal hemorrhage is a major concern in blunt trauma like a motor vehicle accident, but managing circulatory compromise (e.g., controlling bleeding, administering fluids) is addressed only after the airway and breathing are secured. You cannot perfuse organs with blood if there is no oxygen being delivered to the lungs first.
Evaluating extremities for fractures (Option 3) is part of the secondary survey or the "E" (Exposure/Environment) phase, where a full head-to-toe assessment is performed. While painful and important, an isolated limb fracture is not an immediate threat to life compared to airway obstruction or tension pneumothorax.

Related Concepts: The primary assessment is rapid (often 30-60 seconds) and focuses on identifying life-threatening conditions. The secondary assessment is a more detailed head-to-toe exam performed once the patient is stabilized. Remember: Life over limb. Always address threats to the central, vital functions (brain, heart, lungs) before addressing peripheral injuries. Concept Summary

Concept	Description	Nursing Priority
ABCDE Approach	Systematic primary assessment sequence: Airway, Breathing, Circulation, Disability, Exposure.	Always follow this order. Do not skip steps.
Primary Assessment	Rapid evaluation to identify and treat immediate life threats.	Perform first on every emergency/trauma patient.
Secondary Assessment	Detailed head-to-toe exam after primary survey is complete and patient is stable.	Includes vital signs, focused systems assessment, history.
Hypoxia	Deficiency in oxygen reaching tissues. Early signs: anxiety, restlessness, tachycardia.	A key reason to prioritize airway and breathing assessment.

Side-by-Side Comparison!

Assessment Phase	Purpose (The "Why")	Key Actions (The "What")	Timing
Primary Assessment (ABCDE)	Identify and manage immediate life threats.	Look, listen, feel for airway obstruction, breathing effort, major bleeding, level of consciousness.	Within the first 1-2 minutes of encounter.
Secondary Assessment	Identify all other injuries and gather comprehensive data.	Full vital signs, head-to-toe inspection/palpation, patient history (AMPLE), diagnostic tests.	After primary survey is complete and patient is stabilized.

Anatomy, Physiology & Pharmacology Points The ABCDE sequence mirrors the body's physiological priorities for survival. The brainstem controls automatic breathing. If the airway is blocked, oxygen (O2) cannot reach the alveoli for gas exchange. Without oxygen, the myocardium (heart muscle) and brain cells begin to die within minutes. Circulation is vital, but it is ineffective if the blood being pumped is not oxygenated. This is the core pathophysiological rationale for the ABC order. Memory Tips Mnemonic: "All Bad Care Delays Everything" – reminds you of the order: Airway, Breathing, Circulation, Disability, Exposure.
Think: "You can't circulate what you can't breathe." This simple phrase reinforces why Airway and Breathing come before Circulation. High-Frequency NCLEX Topics The ABCDE approach and prioritization in emergency/trauma scenarios are extremely high-yield for the NCLEX-RN. The exam will frequently present you with a multi-problem patient and ask, "What should the nurse do first?" or "Which patient should the nurse assess first?" Your guiding principle must always be: Airway, Breathing, Circulation (ABC). Watch Out for Question Variations! * Instead of asking for the "first" action, the question might ask: "The nurse identifies absent breath sounds on the right side. Which action is a priority?" (Answer: Prepare for chest tube insertion for suspected tension pneumothorax – a Breathing problem). * The scenario could shift to a medical emergency (e.g., heart attack, stroke) but the ABC priority remains the same. * A question might list several completed assessments and ask which finding requires immediate intervention. A finding related to airway or breathing (e.g., stridor, apnea, SpO2 < 90%) would be the priority.

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in the ED. An ambulance brings in Mr. Jones, a 35-year-old involved in a high-speed MVC. He is on a backboard with a cervical collar. He is awake, says "My chest hurts," and appears anxious and tachypneic.

Nursing Intervention Strategy: 1. Primary Assessment (ABCDE): While the EMTs give report, you immediately perform your own primary survey. * A (Airway): Ask, "Mr. Jones, can you tell me your name?" His verbal response confirms a patent airway for now. You note his voice is clear, no gurgling or stridor. * B (Breathing): You look: Is his chest rising symmetrically? You listen: Are breath sounds present and equal bilaterally? You feel: Is there subcutaneous emphysema (crackling under the skin)? You note his respiratory rate is 28/min (tachypnea) and he is using accessory muscles. You apply pulse oximetry: SpO2 is 92% on room air. * C (Circulation): You palpate for a radial pulse (rate, rhythm, strength). You check skin color, temperature, and capillary refill. You look for obvious major bleeding. * D (Disability): You quickly assess his level of consciousness using AVPU (Alert, Voice, Pain, Unresponsive) or Glasgow Coma Scale (GCS). He is Alert. * E (Exposure/Environment): You will fully expose him (while maintaining warmth/ privacy) to look for injuries, but this may be done concurrently or immediately after the initial ABCs.

2. Immediate Actions: Based on your findings (tachypnea, low SpO2, chest pain), you recognize potential for impaired breathing. Your priority actions are: Administer high-flow oxygen via non-rebreather mask, connect to cardiac monitor, and alert the physician/ trauma team of your findings while preparing for possible advanced airway management or chest tube insertion.

Patient Safety and Precautions: In trauma, always assume a cervical spine injury until proven otherwise. Maintain in-line spinal immobilization during the primary assessment. Do not remove the cervical collar until a clinical and/or radiographic clearance is obtained. Nursing Procedure & Medication Flow Procedure: Primary Survey (ABCDE) 1. Approach the patient safely. Ensure scene safety (in the ED, this means appropriate PPE). 2. Airway with C-spine control: Simultaneously assess airway while manually stabilizing the neck. Use jaw-thrust maneuver (not head-tilt-chin-lift) if airway intervention is needed in a trauma patient. 3. Breathing: Look, listen, feel. Provide supplemental oxygen immediately if any signs of respiratory distress or hypoxia are present. 4. Circulation: Check pulse, control obvious external bleeding with direct pressure, assess for signs of shock (tachycardia, hypotension, cool clammy skin). 5. Disability: Perform a rapid neurological screen (AVPU/GCS). 6. Exposure: Fully expose the patient to conduct a thorough visual inspection, then cover with warm blankets to prevent hypothermia. A Word from Your Senior Nurse In the chaos of the emergency department, the ABCDE framework is your anchor. It keeps you focused on what matters most and prevents you from being distracted by dramatic but non-life-threatening injuries. Remember, a patient with a severe head injury (a "D" problem) still needs you to ensure their "A" and "B" are intact first. This systematic approach isn't just for exams—it's the bedrock of safe, effective emergency nursing. On the NCLEX, when you see "first," "priority," or "immediate," let your mind automatically go to "Airway, Breathing, Circulation."
