NSG 311 EXAM 2 CARDIOVASCULAR QUESTIONS WITH COMPLETE ANSWERS

Sinus Arrhythmia


Give this one a try later!


-SA node creates impulse irregular rhythm
-P before every QRS
-T after every QRS
-R waves dont "march out"
-P waves dont "march out"
-HR variable

, -QRS complex much bigger than p-wave bc of mass; ventricles bigger than
atria




How are arrhythmias diagnosed


Give this one a try later!


By analysis of electropgraphic waveform




Assessment/diagnostic finding with HTN


Give this one a try later!


-History & physical
-eye exam
