Priority questions...something to consider (Ans-
▪ change in condition make take priority over ABCs (ex: post op bleeding is
priority over an O2 Sat% of 90%) 1 / 2
▪ pick the patient that is going to die first
You walk into your patient's room and they *don't have a pulse*, what are you going to do?(Ans- CPR, press the code button
You walk into your patient's room and they are *not breathing but have a pulse*, what are you going to do?(Ans- bag resuscitation, press the code button
If you walk into a room with a patient that is in *ventricular fibrillation (v fib)*
▪ How will they present?▪ What must we do to get them out of that state?(Ans- ▪ unconscious, pulseless ▪ shock them with the AED!
If you walk into a room and a patient is alert and oriented, speaking to you, has a pulse, but their cardiac monitor shows they are in *ventricular tachycardia*
▪ What are you going to do?(Ans- ▪ make them bear down (valsalva maneuver) ▪ make them cough (vagal maneuver)
Which cardiac rhythm requires the patient to take *adenosine*?(Ans- Supraventricular Tachycardia (SVT)
What is our priority concern for a patient in *atrial fibrillation (a-fib)*?(Ans- ▪ they may end up with a *blood clot* because the blood is pooling in the atria
