b. Prepare for immediate transport to a hospital

c. Insert an oral airway and begin ventilations with a bag-mask device

d. Check the patient for any medical alert tags

c. Insert an oral airway and begin ventilations with a bag-mask device

You attempt to ventilate a patient with a bag-mask device and notice resistance. The chest does not rise during your ventilation. What should you do?

a. Reposition the airway by hyperextending the head to allow for better anatomic position, then attempt to ventilate

b. Assume there is a foreign body airway obstruction and immediately begin chest compressions

c. Assume there is a foreign body airway obstruction and provide forceful ventilations

d. Reposition the airway by bringing the head back to a neutral position, then reopen the airway and attempt to ventilate

d. Reposition the airway by bringing the head back to a neutral position, then reopen the airway and attempt to ventilate

How can gastric distention be prevented when performing artificial ventilations?

a. Provide rapid, forceful breaths during artificial ventilation over 1 second

While you are performing artificial ventilations on a patient, he vomits. What should you do?

a. Roll the patient onto his side to allow for drainage of emesis
