CEN Practice Exam (Certified Emergency Nurse)

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.
