JBL EMT Practice Exam

Which of the following skills would a layperson most likely be trained to perform before the arrival of EMS?

1. Administration of supplemental oxygen

2. Bleeding control using a tourniquet

3. Insertion of an oropharyngeal airway

4. Obtaining a manual blood pressure

The correct answer is: Administration of supplemental oxygen

Laypeople are often trained in basic first aid skills to provide immediate assistance before professional help arrives. Among the choices given, the administration of supplemental oxygen is a skill that is frequently taught to laypersons in basic first aid and CPR classes. Providing supplemental oxygen can be crucial in cases of respiratory distress or cardiac emergencies, as it helps increase the oxygen supply to the individual while awaiting the arrival of Emergency Medical Services (EMS) personnel. This skill is relatively simple to perform and can have a significant impact on a person's outcome during a medical emergency. Options B, C, and D involve more advanced skills that typically require specific training and expertise, making them less likely to be taught to laypersons for pre-EMS arrival care.
