CPCT Module 5: EKG Questions and Answers Graded A+

CPCT Module 5: EKG Questions and Answers Graded A+ A patient care technician should identify which of the following artifacts is present in the tracing below? Somatic tremor. Present in the tracing. Somatic tremor is an artifact characterized by uneven spikes on the EKG tracing. The most common cause of this artifact is voluntary or involuntary muscle movement. A patient care technician should identify that which of the following is the standard paper speed for a 12-lead EKG? 25mm/sec In which of the following locations should a patient care technician place v5 lead? At the anterior axillary line on the same horizontal level as v4 A patient care technician is caring a patient who is experiencing cardiopulmonary compromise the technician should identify that which of the following structures of the cardiac conduction system initiates the heartbeat? Sinoatrial node (SA node). The SA node is the pacemaker of the heart and initiates the heartbeat A patient care technician identifies p waves are present, but there are missing QRS complete on a patients EKG tracing which of the following actions should the technician take first? Report the rhythm to the nurse. Can indicate a second-degree atrioventricular block, type II, which is a serious dysrhythmia and can quickly deteriorate into a complete heart block. The technician should report this finding to the nurse immediately A patient care technician is providing instructions to a patient who is about to undergo an EKG which of the following statements should the technician make? "You should empty your bladder prior to the test." And rest for 10 to 30 min prior to the test. A patient care technician is performing a 12-lead EKG for a patient . the technician should use which of the following as a reference to compare the cardiac complex during a cardiac cycle on an EKG tracing? Calibration marks. They indicate standardization on the machine for recording and a reference to compare with the cardiac complexes during a cardiac cycle on an EKG tracing. Calibration marks are small, rectangular waveforms that typically appear at the beginning of each lead and indicate the standard paper speed and amplitude of the EKG A patient care technician is planning to clean EKG equipment. which of the following actions should the technician plan to take ? Wipe the equipment with a soft cloth moistened with disinfectant. Disinfecting the EKG equipment helps prevent the spread of infection A patient care technician is obtaining an EKG from a patient who reports chest pain. which of the following changes in a waveform should the technician recognize an indication of a myocardial infarction and report to the nurse immediately? The technician should identify that ST segment elevation with pathologic Q waves and T wave inversion indicates a myocardial infarction. Report asap A patient care technician is preparing to perform a 12-lead EKG for a patient who is pregnant. into which of the following positions should the technician assist the patient? The technician should position the patient slightly on their left side, with a small towel under the right hip. This reduces the pressure from the uterus on the inferior vena cava, promoting adequate circulation and thus improving the accuracy of the EKG tracing A patient care technician should identify that which of the following parts of the EKG machine regulates the height of the waves forms on the tracing? Gain control A patient care technician is preparing to perform 12 leads EKG for a patient who has a heart rate of 225/min. which of the following paper speed setting should the technician expect to provide to prescribe? 50mm/sec to make the tracing easier to read for a patient who has a fast heart rate A patient care technician is monitoring a patient who goes into asystole. which of the following actions should the technician take first? Initiate CPR. If a patient is unresponsive, the first action the technician should take is to initiate CPR. The technician should identify that, if a patient is in asystole, no rhythm or electrical current is traveling though the patient's cardiac conduction system on a sustained basis. It appears as a flat line on the EKG A patient care technician is performing a right- sided 12-lead EKG. For which of the following conditions will a provider request a right
