NEWEST ACTUAL EXAM WITH COMPLETE QUESTIONS AND
VERIFIED ANSWERS |ALREADY GRADED A+|
What is the treatment for second-degree AV block type 1? -
ANSWERS--Asymptomatic: no treatment needed
-Symptomatic: Atropine to increase heart rate or temporary
pacing
What are the characteristics of AV block second-degree: type 2
(Mobitz 2)? -ANSWERS--Fixed PR interval when AV conduction
is present and non conducted P wave when block occurs
-May occur in ratios (2:1, 3:1)
-Regular atrial rhythm, irregular ventricular rhythm
What rhythm is this? -ANSWERS-AV block: 2nd degree type 2
(Mobitz 2)
, Page |2
What is the treatment for second-degree AV block type 2? -
ANSWERS-temporary pacing until permanent pacemaker is
placed
What are the characteristics of third-degree AV block? -
ANSWERS--No impulses from atria are conducted to ventricles
-ventricles are stimulated from secondary pacemaker
-Atria and ventricles function independently of each other
What rhythm is this? -ANSWERS-third-degree AV block
What is the treatment for third-degree AV block? -ANSWERS--
Temporary trancutaneous pacemaker
-Drug therapy to support heart rate and blood pressure (atropine,
epinephrine, dopamine)
-Permanent block requires permanent pacemaker
What is pulseless electrical activity (PEA)? -ANSWERS-
Organized electrical activity observed on ECG in a patient with no
central palpable pulse.
, Page |3
What is the treatment for pulseless electrical activity? -
ANSWERS--Immediate CPR
-Oxygen
-Intubation
-Correct precipitating cause
When does pulseless electrical activity usually happen? -
ANSWERS-After cardiac arrest resuscitative measures
What are premature ventricular contractions (PVCs)? -
ANSWERS-Result of increased irritability of ventricular cells.
Early ventricular complex followed by a pause.
What is this rhythm? -ANSWERS-normal sinus rhythm with a
PVC
What is a group of two PVCs called? -ANSWERS-couplet
