2024 PROFESSIONAL NURSINGSKILLS 2 ECG/EKG FINAL EXAM
WITH CORRECT ANSWERS
What is a PAC? - CORRECT ANSWERS-premature atrial contraction - normal
rhythm is interrupted by atrial contraction
Explain the path of the conduction of the heart. - CORRECT ANSWERS-SA
node, AV node, bundle of His, right and left bundle branches, Purkinje fibers
What is telemetry monitoring? - CORRECT ANSWERS-Used to monitor
patients with suspected or confirmed cardiac abnormalities
Causes of VFib - CORRECT ANSWERS-•Acute MI
•Hypoxia
•Cardiomyopathy
•Hypokalemia, Hypomagnesemia
•Digoxin Toxicity
•Antiarrhythmics
•Cardiac Trauma
•Myocardial ischemia
•Street Drugs (Cocaine, Meth, Heroin=Hypoxia)
Treatment for VFib - CORRECT ANSWERS-•Defibrillate (Shock)
•Epinephrine & Amiodarone
Asystole is also known as... - CORRECT ANSWERS-Ventricular Standstill
Asystole - CORRECT ANSWERS-•Absence of all electrical activity in the
ventricles.
•Atria can still produce P waves.
What are PVCs? - CORRECT ANSWERS-•Premature Ventricular Complexes-
early beat that originates in the ventricle.
•QRS will be wider than usual on the ECG strip.
•Dangerous when they are more frequent than every 6 minutes, coupled,
multifocal or R-on-T (PVC following closely on T-wave of the previous beat).
, •Assess for a pulse deficit. If one is present, the pulse will be different at the
apical pulse then at a peripheral pulse.
What is 1st degree heart block? - CORRECT ANSWERS-Electrical impulse
travels through AV node too slowly, but impulse reaches ventricles
What is a 2nd degree AV block? - CORRECT ANSWERS-a.k.a. Mobitz type I. A
gradually lengthing of the the PR interval that eventually leads to a dropped
QRS.
What is 3rd degree heart block? - CORRECT ANSWERS-Electric impulses do
not reach the ventricles from the atria, so the ventricles create their own
impulse, which causes the ventricles to beat out of sequence with the atria
Can be a life-threatening condition
How do we monitor patients needing telemetry? - CORRECT ANSWERS-
Electrodes are placed in certain areas of the patient's chest in order to
detect and transmit the electrical activity of the heart which is converted by
the cardiac monitor into an ECG tracing.
-Tracings are viewed by specially trained health care personnel & evaluated
for cardiac rhythm changes or abnormalities
Which settings may we find telemetry being used in nursing? - CORRECT
ANSWERS-Most commonly utilized in acute care inpatient and outpatient
clinical setting
Which staff members are appropriate to monitor and care for patients using
telemetry? - CORRECT ANSWERS-Nurses, physicians and ECG technicians
who have undergone training on ECG interpretation may participate in the
care of the patient undergoing telemetry monitoring, however the
assessment should NOT be delegated to non-licensed staff
What is the desired outcome with telemetry monitoring? - CORRECT
ANSWERS-That cardiac rhythm changes or abnormalities will be promptly
identified & treated in order to prevent hemodynamic compromise or other
adverse effects
What is the nurses role in caring for clients undergoing telemetry
monitoring? - CORRECT ANSWERS--Nurses (or ECG technician) may be
employed to watch cardiac monitors and promptly alert the responsible
nurse when an abnormality is seen
-The nurse caring for the patient is responsible for assessing the patient once
they are either notified or recognize themselves any cardiac abnormalities
