CRAT 14 Exam 62 Questions with Verified Answers ______ helps to correct cardiac rhythm conditions - CORRECT ANSWER radiofrequency abalation how does abalations help? - CORRECT ANSWER they help by scarring oreven destroying the tissue in the heart that is triggering the abnormal heart rhythm the axes of the 3 bipolar limb leads form a triangle around the heart known as - CORRECT ANSWER einthoven's triangle einthoven triangle - CORRECT ANSWER is the standard positions for limb leads 1,2,and 3 vtach - CORRECT ANSWER no p waves, no pulse, no co, no qrs, only fluttering of the heart asynchronous or fixed rate mode pacemakers - CORRECT ANSWER initiate impulses at a set rate regardless of the pt's intrinsic heart rate accelerated junctional rhythm - CORRECT ANSWER caused by an irritable focus in the AV junction that speeds up to take over as the heart's pacemaker accelerated junctional rate - CORRECT ANSWER 60-100 bmp high voltage artifact potentials are generally interpreted by the heart monitor as qrs complexes and activate the high rate alarm in a monitoring problem known as - CORRECT ANSWER false high rate alarm false high rate alarm is mostly triggered by muscle movements from the pt ? - CORRECT ANSWER turning in bed or moving extremities, or seizure activity a ____ would be considered an isoelectric interval? - CORRECT ANSWER segment a pt with a flutter will have a normal peripheral or apical pulse due to the fact that the pulse reflects ? - CORRECT ANSWER ventricular contractions a tach would be characterized by on the ecg printout? - CORRECT ANSWER greater than 3 successive ectopic atrial beats at 150-250 bmp and malformed p wave if the pt is experiencing consistent bradycardia they might experience - CORRECT ANSWER cold and clammy skin, dizziness, shortness of breath, feeling tired, chest pain, confused, faint the saw-toothed appearance of the waves on the rhythm strip of an atrial flutter pt are known as? - CORRECT ANSWER flutter waves junctional escape rhythm shows _____ on an ekg strip - CORRECT ANSWER inverted p waves on leads 2,3,and afv (less than .12 sec pr) sinus tach can worsen myocardial ischemia by increasing the heart's demand of? - CORRECT ANSWER oxygen 3 types of ekg - CORRECT ANSWER 24 hr holter monitor, 12 lead standard ekg, stress test ekg each time the heart beats, the amount of blood that is ejected from the ventricles would be considered the ? - CORRECT ANSWER stroke volume chaotic, asynchronous, electrical activity in the atrial tissue - CORRECT ANSWER a fib afib - CORRECT ANSWER originates from the firing of a number of impulses in multiple re-entry pathways one of the most important jobs of the ecg tech? - CORRECT ANSWER communicate caused by exaggerative respiratory movements by the pt - CORRECT ANSWER wandering baseline should not be listed in medical records - CORRECT ANSWER religious preferences 3 letter coding system - CORRECT ANSWER more commonly used toprovide a simple description of pacemaker capabilities 3 letter coding system for pacemakers - CORRECT ANSWER 1st letter-chamber the pacemaker that is being paced, 2nd letter-chamber sensed by pacemaker, 3rd letter-pacemakers response to the sensed event most common cause of limb electrode reversal - CORRECT ANSWER right/left confucion in tech in the sequence method of calculating atrial rate, the tech must memorize a series of numbers to assign to ? - CORRECT ANSWER the heavy blacklines between p waves a compensatory pause may cause - CORRECT ANSWER a pvc that is equal to 2 sinus intervals ______ is stimulated by baroreceptors, specialized nerve cells in the aorta, and internal carotid arteries - CORRECT ANSWER vagus nerve what is not considered a primary characteristic of a cardiac cell - CORRECT ANSWER communicatability 4 characteristics of a cardiac cell - CORRECT ANSWER conductivity, automaticity, contractility, excitability the atria and ventricles beat independently in 3rd° av block and ? - CORRECT ANSWER complete av dissociation _____ is not documented on the top of the ecg recording - CORRECT ANSWER pt's religion documented on the ecg recording - CORRECT ANSWER date, time, pt's name, age, sex, pt id number, physician name, initials of tech, pt medication, vital signs, height, weight a pacemaker could be inserted to help a pt maintain a - CORRECT ANSWER steady heart rate when the electrical impulses are generated in the ventricles instead of the atria, atrial kick is lost and cardiac out decreases by - CORRECT ANSWER 30% if a pt's shock has been caused by a cardiac tamponade I would be considered ______ shock - CORRECT ANSWER cardiogenic septic shock - CORRECT ANSWER happens when bacterial infections cause toxic shock syndrome hypovolemic shock - CORRECT ANSWER happens when the total volume of blood in the body drops below normal anaphyalctic shock - CORRECT ANSWER happens when there is a severe allergy reaction such a bee sting when the atria and ventricles beat but totally independent of each other - CORRECT ANSWER av dissociation if a cardiac rhythm is regular, what would be an easy way to determine the heart rate - CORRECT ANSWER count the # of large squares between identical points and divide by 300 unreliable results - CORRECT ANSWER are not one of the drawbacks with hardwired monitoring not a complication of a flutter - CORRECT ANSWER osteoporosis complications of a flutter - CORRECT ANSWER pulmonary emboli, mural thrombi, systemic emboli, hemodynamic instability might be a considered a cause of a shortened qt interval - CORRECT ANSWER hypercalcemia, certain genetic abnormalities, hyperkalemia the method of calculating the atrial rate that best employed when there is an irregular rate - CORRECT ANSWER 10 times method sinus arrhythmia is a rhythm that originates in the sinus node and discharges impulses - CORRECT ANSWER irregularly the most fundamental intervention for improving nurse physician communication would be - CORRECT ANSWER fostering an organizational culture that is patient-centric, safety based, and supportive of teamwork afib is defined by an absence of - CORRECT ANSWER p waves purkinje fibers end in minuscule filaments that directly depolarize - CORRECT ANSWER ventricular myocytes abnormalities in the cardiac rate and rhythm would be considered - CORRECT ANSWER dysrhythmias if the tech is applying a cardiac monitor and receives a poor signal, what should they do?
