ACLS Questions and Answers 100% Pass in cardiac arrest when do you first introduce medical intervention? which drug? after 2 rounds of CPR/shock after 2nd shock give 1 mg epinephrine every 3-5 minutes when do you introduce amiodarone during cardiac arrest? after the 3rd shock give 300 mg bolus of amiodarone if second dose is needed give 150mg as second dose what rhythms are shockable in cardiac arrest VF VT what rhythms are not shockable in cardiac arrest asystole PEA if you are in an unshoc...

Exam Questions Paramedic EKG Rhythms With 100% Correct Answers. Normal Sinus Rhythm - CORRECT ANSWER 60-100 bpm all complexes normal and evenly spaced (P, QRS, T) Sinus Arrest - CORRECT ANSWER - SA node doesn't fire - notice absence of P-wave for a complete cycle (a missed cycle) Sinus arrhythmia - CORRECT ANSWER all complexes normal but rhythmically irreg - normal finding (esp in young pts) that has to do with breathing (rate: inhale-increase, exhale-decrease) Sinus Bradycardi...

Electrocardiogram (ECG) correct answer: Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) correct answer: Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? correct answer: Only monitors Straight line when machine is turned on but not connected to the patient correct answer: Isoelectric = no current ...

Cardiac Telemetry Exam 56 Questions with Verified Answers Normal Conduction System - CORRECT ANSWER -SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm -Internodal Pathways = Pathways connecting SA Node and AV Node -AV Node = Backup pacemaker, rate of 40-60 bpm -Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system of heart -L & R Bundle Brancehs = lead to left & right of the myocardium -Purkinje Fibers / Network = ends of the muscle, la...

What are the 6 parts of the cardiac conduction cycle? correct answer: -SA node -Internodal pathways -AV node -Bundle of His -R and L bundle branches -Purkinje fibers What is the SA node? correct answer: -Small cluster of cells located in the upper R atrium *-Pacemaker of the heart* What are internodal pathways? correct answer: Impulses sent by the SA node that travel through the atrial muscle fibers via the intra-atrial pathways Allows for simultaneous depolarization and contra...
