• Question 161:

  You enter a patient's room and find the patient not breathing, no pulse, and unresponsive. You have called for help. What is the next step?

  A. Bag mask ventilations

  B. Chest compressions

  C. Oxygen

  D. Open airway

  Correct Answer: B

  New standards in CPR emphasize chest compressions over airway, so the next step after calling for help is to check the pulse and begin chest compressions. Chest compressions should be given immediately (30 for an adult patient), and then followed by opening the airway and beginning respirations. Ventilation is only initiated when the airway is open or patent, as oxygen is not needed until the patient is breathing.
