Experience the Quality With Free Advanced EMT Exam Questions That Helps Candidates Pass

The epiglottis covers the trachea during swallowing to prevent aspiration. The uvula (A) guides food but not airway protection. Vocal cords (C) produce sound. The trachea (D) is the airway itself.

START triage: RR >30, absent radial pulse (poor perfusion), altered perfusion = Red (Immediate), even if patient can follow commands. Green = walking wounded, Yellow = delayed, Black = deceased.

Intersections are the most dangerous point for EMS collisions. AEMT drivers must stop or slow sufficiently to clear each lane, even with lights/siren. Assuming traffic will yield (C) is unsafe. Waving traffic (D) creates liability. Rapid approach (A) risks collision. EMS safety training emphasizes defensive driving, due regard, and compliance with state law.

Explanation (150–250 words):

This patient has signs of hemorrhagic shock from abdominal trauma. The key AEMT actions are airway/oxygen support, rapid IV/IO access with isotonic fluids per protocol, and expedited transport to surgical facility. Abdominal binders (A) are not recommended. Observation only (C) delays definitive care. Oral fluids (D) are contraindicated. Monitoring vitals, reassessment, and minimizing on-scene time are critical.

For an unresponsive foreign body airway obstruction, first attempt ventilation. If unsuccessful, begin chest compressions and re-check airway. Back blows/abdominal thrusts (A) are for responsive children. Recovery (D) is inappropriate here.
