NUR 347 Exam 4
- SB treatment
Answer
Atropine (works on SA), pacermaker prn
- ST treatment
Answer
Fix the underlying issue (e.g. fluids if hypovol, antipyretics if fever, etc.)
- A-FIB/A-flutter treatment
Answer
Less than 24 hours
Dilitezam (Cardizem)/ Amiodarone
More than 24 hours
Anticogaulants , TEE(transespohageal echo, look for clots in atria, scope goes down their throat), meds to slow down to less than 100 (PRN; beta-blocker, dig).
- SVT Treatment
Answer 1 / 3
Modified Valsalva, adenosine (6,12,12) - push FAST, cardiovert PRN
- VT with pulse
Answer
Amiodarone 150 mg bolus and gtt, cardiovert asap/PRN
- VT without pulse
Answer
CPR, Epi 1mg q 3-5 minutes, AMIO 300 mg push x 1, then 150 mg IVP, defib asap

8. 3 AVB (CHB)
Answer
temp-pacing, fix the problem or perm pacer, related to an MI
- P wave
Answer
Atrial depolarization ( signal from SA to AV) <.12 seconds
- QRS complex 2 / 3
Answer
Ventricular depolarization (ventricles contraction) <.04-.12
- T wave
Answer
ventricular repolarization (ventricles relax) <.16
- QT interval
Answer
beginning or Q to end of T. full time it takes for the ventricles to fully contract and then relax. if it prolong, the ventricles is trying to contract before it has had the time to relax
- ST segment
Answer
at isoelectric line. if elevated by more than 2 small boxes could mean infarction or ischemia of heart muscle (ST elevation)
- PR segment
Answer
end of P to beginning of Q. pause between SA and AV
- What is SVT (Supraventricular Tachycardia)?
Answer
Ventricles are contracting too fast because AV or an atrial cell is firing in a continuous loop, every signal gets through
