ANSWERS ✔✔Supraventricular Tachycardia (SVT)
What is our priority concern for a patient in *atrial fibrillation (a-fib)*? -
CORRECT ANSWERS ✔✔▪ they may end up with a *blood clot* because the
blood is pooling in the atria
Nursing Interventions: *A-fib RVR* - CORRECT ANSWERS ✔✔*control RVR
for patient:*
▪ give anticoagulants
▪ beta blockers, digoxin, diltiazem
▪ if meds don't work...cardioversion (synchronized shock to re-start the
rhythm)
▪ if cardioversion doesn't work...ablation
If you have a patient who comes into the ED and they are having an MI, what
