Download CET Practice Test: Comprehensive Solutions for 2023 and more Exams Advanced Education in PDF only on Docsity! CET Practice Test complete solutions with latest updates 2023 Which of the following is the only calculating method available for both regular and irregular rhythms? Correct Answer: The 6- Second method During a stress test, an EKG tech notices the patient appears to be hyperventilating. Which of the following is an appropriate course of action for the tech? Correct Answer: Check the patient's respiratory rate. Checking the rate will allow the CET to confirm hyperventilation. Which of the following sensitivity settings would produce a calibration box that measures 10mm tall? Correct Answer: A sensitivity setting of 1 Which of the following methods for calculating a patient's heart rate from the EKG is correct? Correct Answer: Divide 1,500 by the number of small boxes between two R waves to calculate a full cardiac cycle. 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 the test, which of the following actions should the CET take first:? Correct Answer: The CET should notify the physician immediately after stopping the test. Which of the following describes the correct electrode placement for lead V5? Correct Answer: Anterior axillary line, 5th intercostal space. Calculate the heart rate in the tracing below using the 1500 method. 1500 / 22 Correct Answer: 68/min The R-R interval on a patient's tracing had five large boxes. Which of the following is the patient's heart rate? Correct Answer: The rate is calculated using the 300 method. 330/5 = 60 Where the EKG tech place the electrode for lead V5? Correct Answer: On the left anterior axillary line, horizontal to V4 Which of the following waves would an EKG tech measure to evaluate for atrial enlargement? Correct Answer: The P wave is the only wave that is measure outside of an interval or a complex. What is the name of the arrhythmia in the EKG tracing below? Correct Answer: Atrial flutter Characterized by flutter waves between QRS complexes. The most common flutter to ventricular response ration is 2:1 Which of the following lead groups are bipolar leads? Correct Answer: I,II, and III Which of the following artifacts is shown in the tracing below? Correct Answer: Wandering Baseline Because the tracing moves up and down. An EKG tech is working with a patient who has a below the knee amputation of the left leg. WHere should the tech place the right- leg electrode? Correct Answer: On the lower right thigh. The electrodes need to remain equidistant from one another, so moving the left leg electrode to the thigh requires moving the right leg electrode to the thigh. When performing a posterior EKG, which of the following is the correct location for a placement of lead V8? Correct Answer: Left midscapular line. Which of the following signs should the EKG tech be concerned about in a patient undergoing stress testing? Correct Answer: Decreased heart rate Can be a result of ischemia and should prompt the CET to stop the test and notify the physician. Which of the following statements made by the EKG tech correctly prepares the patient for telemetry monitoring? Correct Answer: You may clean the skin with an alcohol pad. A tech is preparing a patient for a 12 lead EKG. Which of the following is the correct placement for lead V4? Correct Answer: The 5th intercostal space at the midclavicular line. After completing an EKG on a patient, which of the following should the tech preform next? Correct Answer: Before disconnecting the patient from the machine, check that the tracing is free from artifacts. Which of the following rhythms is characterized by upright P waves, narrow QRS complexes, and a ventricular rate between 60 and 100/min? Correct Answer: Sinus Rhythm. An EKG tech has just provided patient education prior to a stress test. Which of the following statements made by the patient indicates an understanding of the preparation? Correct Answer: " I may smoke the night before the exam" Which of the following can cause sinus arrhythmia in children? Correct Answer: The respiration of the patient. Arrhythmia is characterized by a cyclic change in respiration. For a 5-Lead electrode placement for ambulatory monitoring, where should the EKG tech place the green ground electrode? Correct Answer: On a rb on the lower right side. Which of the following is the most appropriate site for taking the pulse of an infant? Correct Answer: The brachial artery The easiest site to obtain a pulse in an infant because of its proximity to the surface of the skin. Repairs on an EKG machine should be preformed by which of the following? Correct Answer: A biomedical technologist They are trained in medical device maintenance. What is the name of the arrhythmia in the EKG tracing below? Correct Answer: Atrial Fibrillation characterized by the presence of fibrillatory waves between QRS complexes and an irregularly irregular rhythm In a normal patient, which of the following is the expected shape and direction of the P wave in lead II? Correct Answer: Rounded and upright
