Verified Answers ALREADY GRADED A+!!
properties of cardiac cells - ANSWERS--Automaticity - Ability to initiate
an impulse spontaneously and continuously
-Excitability - Ability to be electrically stimulated
-Conductivity - Ability to transmit an impulse along a membrane in an
orderly manner
-Contractility - Ability to respond mechanically to an impulse
SA node - ANSWERS--pacemaker of the heart
-located in Rt atrium
-produces heart rate
-beats at *60-100 bpm*
parasympathetic nervous system - ANSWERS-(vagal response)
-decreases rate of SA node
,-*decreases heart rate*
-slows impulse conduction of AV node
sympathetic nervous system - ANSWERS-(fight or flight)
-increases rate of SA node
-*increases heart rate*
-increases impulse conduction of AV node
-increases cardiac contractility
domains of nursing practice - ANSWERS-where you practice nursing
nursing practice - ANSWERS--the protection, promotion, and
optimization of health
-preventing illness and injury
-alleviation of suffering
nursing process - ANSWERS--assessment
-diagnosis
-planning
-implementation
-evaluation
QSEN competencies - ANSWERS--Patient - Centered Care
-Teamwork and Collaboration
-Safety
,-Quality Improvement
-Informatics
-Evidence - Based Practice
5 rights of delegation - ANSWERS-1. Right Task
2. Right Circumstance
3. Right Person
4. Right Directions / Communication
5. Right Supervision / Evaluation
Electrocardiogram monitoring - ANSWERS--Graphic tracing of
electrical impulses produced by heart
-Waveforms of ECG represent activity of charged ions across
membranes of myocardial cells
depolarization - ANSWERS-contraction
repolarization - ANSWERS-Return of the cell to resting state
secondary pacemakers of the heart - ANSWERS--AV Node: beats at 40-
60 bpm
-His-Purkinje Fibers: 20-40 bpm
, reading ECG - ANSWERS--small / little boxes = 0.04 seconds
-bolded box lines = 0.2 seconds
isoelectric line - ANSWERS-The baseline of the ECG
PR interval (PRI) - ANSWERS--from onset of P wave to onset of QRS
-Normal duration = *0.12-0.20 sec*
-represents atria to ventricular conduction time
prolonged PR interval - ANSWERS-may indicate first degree heart
block
QT interval - ANSWERS--total ventricular activity
-*0.34-0.43*
-measured from beginning of QRS to the end of the T wave
-varies with heart rate
-less than half of the R to R interval
P wave - ANSWERS-caused by atrial depolarization
QRS complex - ANSWERS--ventricular depolarization
-*less than 0.12 seconds*
