Junctional rhythms have retrograde conduction to the ventricles

You have completed the initial assessment on a 62-year-old male complaining of the sudden onset of epigastric pain. His airway is patent, his breathing is fast but adequate, and his radial pulse is weak and thready. His pulse rate is 124 beats per minute and his skin is cool and moist to the touch. Your next action would be to:

A) obtain a blood pressure in both arms. B) perform a secondary assessment. C) place the patient on the stretcher and move him to the ambulance. D) apply supplemental oxygen.
