This patient’s presentation—older age, severe back pain radiating to the chest, hypotension, and a pulsating abdominal mass—is highly suggestive of an abdominal aortic aneurysm (AAA). NREMT teaching stresses early recognition of life-threatening medical conditions and avoiding interventions that could worsen the patient’s condition.
Option A (Position of comfort) is correct because patients with suspected AAA should be kept calm and positioned in a way that minimizes pain and stress, which can reduce sympathetic stimulation and the risk of aneurysm rupture.
Option D (Supplemental oxygen) is correct because the patient’s SpO₂ is 89%, indicating hypoxia. NREMT guidelines recommend administering oxygen to maintain adequate oxygenation in critically ill or potentially unstable patients.
Option B is incorrect because AED pads are not indicated unless the patient is in cardiac arrest or has a high risk of imminent arrest. There is no evidence of dysrhythmia or arrest at this time.
Option C is incorrect because aspirin is indicated for suspected acute coronary syndromes, not AAA. Aspirin could worsen internal bleeding if the aneurysm ruptures.
Option E is incorrect because nitroglycerin can cause vasodilation and hypotension, potentially precipitating aneurysm rupture.
In summary, NREMT emphasizes supportive care, oxygenation, and rapid transport for suspected AAA while avoiding medications that increase bleeding risk or lower blood pressure.
