Med Surg II Exam 1 Questions and Answers Latest Updated Version. FOCUS POINTS EXAM 1 CARDIAC (MED SURG II EXAM 1) Dysrhythmias Abnormal heart rate or rhythm Caused by a disturbance in electrical conduction of the heart, not by abnormal heart structure May be benign or have lethal consequences Cardiac output = stroke volume x HR Patho ● 5 unique properties of cardiac cells ○ Automaticity → spontaneously initiate an electrical impulse ■ Changes in automaticity cause tachydysrhyth...

Telemetry Test Questions with 100% Correct Answers Update Assessing new onset ST elevation - Answer -presence of pain, SOB, or discomfort -check for lead placement accuracy -position patient in supine position with HOB up 30" and reassess ST -12 lead EKG and call MD Why is measuring QTc important? - Answer B/c a prolonged QTc interval increases the risk of developing a lethal dysrhythmia ST segment may reflect myocardial injury or ischemia if? - Answer it deviates from the isoele...

Basic Cardiac Rhythm Interpretation Advanced Exam Review Update A+ 1 / 22 P Wave Atrial Depolarization stim￾ulated by the firing of the SA node. Evaluate: consistent ap￾pearance and 1:1 relation￾ship with QRS complex. If not identical some, or all, may be atrial, but not SA node, in origin. IF >1 P-wave precedes QRS a heart block may be present. Basic Cardiac Rhythm Interpretation Advanced Exam Review Update A+ 2 / 22 PR Interval Impulse traveling time from the atriu...

Chapter 4- EKG's and Interpretation and Management of Basic Dysrhythmias Questions And Answers cardiac electrophysiology - CORRECT ANSWER-study of the electrical properties of the cardiac muscle -electricity flows through the heart in a regular, measured pattern and results in contraction of the cardiac muscle -electrical activity precedes mechanical activity (contraction of the heart) -EKG looks at the electrical activity properties of cardiac cells - CORRECT ANSWER-specialized cardia...

Excitability correct answers the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization correct answers occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity correct answers the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex:...
