Hypothetical situation: On the monitor a patient suddenly begins to brady downward --> asystole. The RN's begin CPR and bring in the crash cart. Now to choose the first drug: the RN gives atropine 1mg first because of the preceding bradycardia and it works, patient is saved. Was this appropriate and in accordance with ACLS guidelines or should 1 of epi have been given first and followed later by atropine? Lets say that based on the patient situation the RN suspects severe vasovagal stimulation as the initial cause of the bradycardia--> asystole. In my mind atropine seems like the right drug to give but does an ACLS nurse have that privilege or are we legally bound to progress through the algorithm in order with 1mg of epi first? Last question, can you give the 1mg of epi immediately followed by 1 of atropine or should you first let the epi do its thing and give atropine 3-5min later? Haven't been in many codes yet and was just wanting some clarification. Thanks in advance.
