NCCT Review #3: EKG Certification Exam Prep Questions With 100% Verified Correct Detailed Answers.

What leads look at the interventricular septum? - correct answer v1 and v2 A CET observes varying R-R intervals on a 2- year- old patient's EKG. "The irregularity is normal in result of respiration."Is the statement made by the CET correct? True or False - correct answer False, plus the CET should not be discussing the results with patient.

The patient in turn states" I will push the event button if I'm experiencing discomfort." Does this statement indicate the patient understands? - correct answer What calculating method can be used when calculating regular but interrupted and irregular rhythms? - correct answer six- second method During a stress test, an EKG technician notices the patient appears to be hyperventilating. What is an appropriate course of action for the technician? - correct answer Check the patients respiratory rate. Which settings on the EKG machine will produce a calibration box that measures 10mm tall? - correct answer 1 Which methods for calculating a patients heart rate from the EKG is most accurate? - correct answer divide 1,500 by the number of little boxes between the two consecutive R waves What is the correct order of a complete cardiac cycle in the normal heart? - correct answer P wave, QRS complex, and T wave While performing a stress test, the patient complains of dizziness. After stopping his test, what actions should the CET take first? - correct answer Notify the Physician What is the correct electrode placement for lead V5?F - correct answer Anterior axillary line, 5th intercostal space The R-R interval on a patients tracing has five large boxes.

True or False - correct answer True A technician is preparing a patient for a 12-lead EKG. What is the correct placement for lead V4? - correct answer The 5th intercostal space at the midclavicular line. After completing an EKG on a patient, what should the technician perform next? - correct answer before disconnecting the patient from the machine, check that the tracing is free from artifacts. Which rhythm is characterized by upright P waves, narrow QRS complexes, and a ventricular rate between 60 and 100/min? - correct answer sinus rhythm An EKG technician has just provided patient education prior to a stress test. The statement "I may smoke the night before the exam" can this statement made by the patient indicate an understanding of the preparation? true or false - correct answer true, the patient may smoke the night before but not right before the exam due to an increase in heart rate and possible respiratory rate increase. What can cause sinus arrhythmia in children? - correct answer the respiration of the patient For 5 lead electrode placement for ambulatory monitoring, where should the EKG technician place the green ground electrode ? - correct answer on the rib on the lower right side What is the most appropriate site for taking the pulse of an infant? - correct answer Brachial artery Repairs on an EKG machine should be performed by whom? - correct answer A biomedical technologist In a normal patient , what is the expected shape and direction of the P wave in lead II? - correct answer rounded and upright Which lead is created between the left arm and left leg? - correct answer III What are some symptoms that would be the cause for an EKG technician to stop a stress test? - correct answer Dizziness, syncope, vomiting, shock For a 5 lead EKG, where should the red lead be placed? - correct answer Lower left torso, or left leg For which patient would an EKG technician expect to see somatic interference on the EKG monitor? - correct answer patient seizing or shivering "Electrical interference on the EKG is not caused by cell phones ." true or false - correct answer False A myocardial infarction can often be detected by the presence of what signature wave on an EKG tracing? - correct answer pathologic Q waves An EKG technician is measuring the intervals on an EKG tracing. What is an anticipated finding of an impaired conduction through the AV node? - correct answer prolonged PR interval What EKG changes is associated with myocardial injury? - correct answer ST segment elevation What is the most accurate site for measuring a patients body temperature? - correct answer Rectum An Ekg has a 2mm ST elevation in leads 1, AVL, V5, and V6. What type of infarction would this represent? - correct answer lateral infarction A patient has been ordered to wear a Holter monitor for 24hr. Does this statement from the patient indicate understanding? "I should record spontaneous symptoms unrelated to an activity." True or False - correct answer True, anything out of the ordinary should be recorded. What is a cause for discontinuing a stress test? - correct answer ST segment elevation A technician notices that none of the leads are giving readings.
