CCI TEST 2 QUESTIONS AND ANSWERS ALREADY PASSED

CCI TEST 2 QUESTIONS AND ANSWERS ALREADY PASSED Which of the following leads normally produces a negative P wave and a predominately negative QRS on the EKG? AVR When performing an exercise stress test 85% of the predicted maximum heart rate is used to determine the end point of a sub maximal exercise test Which of the following is an advantage of a three channel EKG machine all the leads can be recorded simultaneously Exercises stress test is most often used to evaluate ischemic changes due to coronary artery disease fifth intercostal space, left medclavicular line is a landmark for what precordial electrode placement V4 Given a blood pressure of 120/80, what formula would you use to determine the pulse pressure 120-80 What wave on the ECG represents ventricular repolarization T wave Vasodilation with exercise will result in decreases systemic vascular resistance Which of the following heart rates is most consistent with atrial flutter with 2:1 block 150 bpm What EKG finding is most consistent with hyperkalemia tall peaked T waves Patient receiving beta blockers will increases their R-R interval The purpose in placing one of the exploring leads of the Holter monitor on or near the V5 position accentuate ventricular repolarization If the systolic blood pressure drops 20mm Hg during the third stage of the Bruce protocol for exercise stress test the test should be terminated Which of the following is a normal EKG response of exercise stress testing, as the patient's heart rate exceeds 150 bpm both the QRS complex increases and the T wave decreases in amplitude Which of the following veins transports oxygenated blood pulmonary veins A prolonged QT interval due to quinidine toxicity has an increased risk of ventricular tachyarrhythmias When using the hexacial reference system, the POSITIVE pole of lead 3 is + 120 degrees Small vertical lines across the top of single channel EKG graph paper indicates 3 second time intervals
