1Assess for signs of hypothermia and begin rewarming measures
2Monitor for signs of increased intracranial pressure and neurological deterioration✓ 정답
3Evaluate respiratory status and oxygen saturation levels
4Check for water aspiration and pulmonary edema
해설
Following submersion injury, cerebral hypoxia can lead to cerebral edema and increased intracranial pressure, which is the most serious complication requiring immediate intervention. While respiratory and hypothermia assessments are important, neurological monitoring is the priority to prevent secondary brain injury.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing assessment for a pediatric patient after a near-drowning (submersion injury). The core theme is the ABC (Airway, Breathing, Circulation) principle with a critical nuance. While the child is now conscious and breathing, the greatest threat after successful resuscitation from a hypoxic event is Key Point!secondary brain injury due to cerebral edema and increased intracranial pressure (ICP). The brain is exquisitely sensitive to hypoxia, and neuronal damage can continue to evolve even after the initial event.
Answer Rationale: The correct answer is ② Monitor for signs of increased intracranial pressure and neurological deterioration. Although the child is conscious, "lethargic" is a significant change in level of consciousness (LOC), which is the earliest and most sensitive sign of rising ICP. The priority is to establish a neurological baseline and vigilantly monitor for deterioration (e.g., decreasing LOC, vomiting, pupillary changes, posturing) to guide immediate interventions (e.g., head elevation, hyperventilation, osmotic diuretics) and prevent irreversible brain damage.
Distractor Analysis:
Watch out for confusion! Option ③ (Evaluate respiratory status) is a very strong distractor because airway and breathing are always the first priority in initial resuscitation. However, the scenario states the child "was successfully resuscitated at the scene and is now conscious." This implies the ABCs have been initially managed. The question is asking for the next priority assessment in the ED, which shifts to preventing the most lethal complication: brain injury.
Option ① (Assess for hypothermia) is important, as drowning often leads to hypothermia, which can be neuroprotective. However, rewarming must be done cautiously and is not the immediate assessment priority over detecting neurological decline.
Option ④ (Check for water aspiration) is essentially part of the respiratory assessment. While pulmonary edema (often non-cardiogenic, from aspiration) is a common complication, it would manifest with respiratory distress, which the scenario does not currently describe. Neurological monitoring supersedes this in a stable-but-altered patient.
Related Concepts: The nursing process here involves rapid neurological assessment using tools like the Pediatric Glasgow Coma Scale (GCS). Understanding the pathophysiology of cerebral hypoxia → cellular swelling → increased ICP → herniation is crucial. Management focuses on maintaining cerebral perfusion pressure (CPP) and reducing cerebral metabolic demand.
Concept Summary
Concept
Key Takeaway
Submersion Injury Priority
After initial ABC stabilization, the priority shifts to neurological protection and monitoring for increased ICP.
Early Sign of Increased ICP
Key Point! Change in Level of Consciousness (LOC) (e.g., lethargy, irritability, confusion).
Frequent neuro checks, maintain head of bed elevated, avoid neck flexion, monitor for vomiting, seizure activity, and vital sign changes (Cushing's triad: hypertension, bradycardia, irregular respirations).
Side-by-Side Comparison!
Assessment Priority
Initial Scene/Resuscitation
Post-Resuscitation in ED (Stable Airway)
Primary Focus
ABCs: Airway, Breathing, Circulation. Start CPR if needed.
Neurological Status: Prevent secondary brain injury from cerebral edema/ICP.
Key Actions
Rescue breaths, chest compressions, spinal immobilization if trauma suspected.
Establish neuro baseline (Pediatric GCS), monitor for deterioration, prepare for possible intubation for hyperventilation.
Rationale
Immediate survival depends on oxygenating the brain and heart.
Long-term neurological outcome depends on minimizing ongoing brain injury.
Anatomy, Physiology & Pharmacology Points
Pathophysiology: The brain has minimal energy reserves. Hypoxia leads to failure of the sodium-potassium pump (Na+/K+ ATPase). Sodium and water accumulate inside neurons, causing cytotoxic edema. This increases intracranial volume within the fixed space of the skull, raising pressure and compromising blood flow.
Monro-Kellie Doctrine: The skull is a rigid container holding brain tissue, blood, and cerebrospinal fluid (CSF). An increase in one component (e.g., edematous brain tissue) must be compensated for by a decrease in another, or ICP will rise.
Pharmacology Connection: If ICP rises, medications like Mannitol (an osmotic diuretic) or Hypertonic saline may be used to draw fluid from brain tissue into the vasculature, reducing cerebral edema.
Memory Tips
Think "Brain After Drowning": The brain was without oxygen. Even after the heart and lungs are working, the brain is swollen and angry. Your job is to watch it like a hawk.

High-Frequency NCLEX Topics
NCLEX loves to test priority-setting and delegation in emergency pediatric scenarios. Near-drowning is a classic case. Remember: Airway/Breathing is always first unless it has already been addressed. The exam will often give you a patient who is "now breathing" or "has a pulse" to shift your focus to the next most critical system—often the neurological system after a hypoxic insult.
Watch Out for Question Variations!
Shift from Assessment to Intervention: "The nurse notes the child's pupils are now sluggish and unequal. Which action should the nurse take first?" (Answer might be: Prepare for emergency intubation and hyperventilation to lower PaCO2 and constrict cerebral blood vessels).
Shift to Family Education: "Which statement by the parent indicates a need for further teaching about water safety?" (Focus on constant supervision, barriers around pools, CPR knowledge).
Adding a Complication: The scenario might add "the child is now coughing up pink, frothy sputum." This would make pulmonary edema/respiratory status the concurrent priority with neuro status, testing your ability to manage multiple crises.
Nursing Clinical Practice GuideClinical Scenario: You are the ED nurse receiving a 4-year-old, lethargic child from EMS. The parents are distraught. The child is on a stretcher with oxygen via non-rebreather mask, heart monitor leads placed, and an IV line established.
Nursing Intervention Strategy:
Immediate Assessment & Baseline:
Neurological: Perform a quick but thorough Pediatric Glasgow Coma Scale (GCS) assessment. Document eye opening, verbal response (inappropriate words/cries), and motor response (localizes pain? withdraws?). Check pupil size, equality, and reaction to light. Note any posturing.
Vital Signs: Obtain full set, paying close attention to Cushing's Triad signs of late-stage increased ICP: Hypertension, Bradycardia, and Irregular respirations.
Respiratory: While neuro is priority, concurrently auscultate lung sounds for crackles (aspiration/pulmonary edema), assess work of breathing, and ensure pulse oximetry is monitoring continuously (SpO2 > 95% target).
Ongoing Monitoring & Care:
Establish a neuro check schedule (e.g., every 15 minutes). Any decline in GCS score by 2 or more points is a medical emergency.
Maintain head of bed elevated to 30 degrees (unless spinal precautions are in place) to promote venous drainage from the brain.
Keep the head in midline alignment to prevent jugular vein compression.
Minimize stimuli (quiet, dim light) to reduce cerebral metabolic demand.
Monitor temperature. Hypothermia may be present; rewarm slowly and passively (e.g., warm blankets) to avoid rapid vasodilation, which can increase ICP.
Communication & Support:
Provide clear, calm updates to the parents. Explain the purpose of frequent checks.
Prepare for possible transfer to Pediatric ICU (PICU) for advanced neuromonitoring (e.g., ICP bolt).
Patient Safety and Precautions:
Avoid: Over-sedation unless directed (need to assess neuro status). Over-hydration with hypotonic IV fluids (can worsen cerebral edema).
Monitor for: Seizure activity, which increases cerebral metabolic rate and ICP. Have seizure precautions ready.
Medication Caution: If Mannitol is ordered, administer via a filter needle, monitor for fluid and electrolyte shifts (especially hyperkalemia), and ensure adequate urine output.
Nursing Procedure & Medication FlowNeurological Assessment Procedure:
1. Level of Consciousness (LOC): Use age-appropriate stimuli. "Hi [child's name], open your eyes." Progress to gentle tactile stimulus if no response.
2. Pupils: "PERRLA" - Pupils Equal, Round, Reactive to Light and Accommodation. Sluggish or fixed pupils are a red flag.
3. Motor Response: "Squeeze my fingers." Observe for purposeful movement, withdrawal from pain, or abnormal posturing (decorticate or decerebrate).
4. Vital Signs: Trend the data. A widening pulse pressure (increasing difference between systolic and diastolic) is an early sign of increasing ICP.
Medication: Mannitol (Osmitrol)
- Action: Osmotic diuretic. Draws fluid from brain tissue and extravascular space into the bloodstream.
- Nursing Considerations: Administer via IV pump over 20-60 minutes as ordered. Use an in-line filter. Monitor for hypotension (rapid fluid shift), electrolyte imbalance, and monitor intake & output closely. Assess for signs of worsening heart failure (can increase intravascular volume initially).
A Word from Your Senior Nurse
"In the chaos of the ED, it's easy to get pulled in ten directions. With this child, your eyes and hands need to be doing two things at once: ensuring oxygen is getting to the lungs while your brain is laser-focused on whether oxygen is getting to the brain cells. That lethargy is your patient's brain whispering for help. Documenting a precise neuro baseline is your most powerful tool—it turns your subjective worry into objective data that can trigger life-saving interventions. Never underestimate the power of a thorough, documented assessment. It's the foundation of everything we do."
