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...

Normal Sinus Rhythm correct answers 60-100 bpm all complexes normal and evenly spaced (P, QRS, T) Sinus Arrest correct answers - SA node doesn't fire - notice absence of P-wave for a complete cycle (a missed cycle) Sinus arrhythmia correct answers all complexes normal but rhythmically irreg - normal finding (esp in young pts) that has to do with breathing (rate: inhale-increase, exhale-decrease) Sinus Bradycardia correct answers <60 normal sinus rhythm Sinus Tachycardia corre...

• Normal rhythm • HR = 300/4.4 = 68 bpm • P wave = sinus origin • QRS complex = preceded by P wave, normal • Normal sinus rhythm • Tall QRS complex, narrow, preceded by P wave • HR = <60 bpm (bradycardia) • P wave = sinus origin • Sinus bradycardia Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:00 Full screen • Irregular rhythm (slow --> speeds up --> slows down) • HR = 70 bpm • P...

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...

NCLEX Cardiac Critical Care Questions and Answers Rated A+ The nurse is caring for an adult pt who is admitted with chest pain that began four hours ago. Which test will be most specific in identifying acute heart damage? 1. troponin 2. CPK 3. CK-MB 4. cholesterol Answer: 1 Rationale 1: Troponin is primarily located in cardiac muscle & can indicate myocardial infarction or unstable angina. Troponin elevates at two to four hours after myocardial infarction. Rationale 2,3: CPK & ...

Chapter 35: Dysrhythmias | Questions, Answers and Rationales A patient admitted with syncope has continuous ECG monitoring. An examination of the rhythm strip reveals the following: atrial rate 74 beats/min and regular; ventricular rate 62 beats/min and irregular; P wave normal shape; PR interval lengthens progressively until a P wave is not conducted; QRS normal shape. The priority nursing intervention would be to a. give epinephrine 1 mg IV push. b. prepare for synchronized cardioversion. c...
