EKG Exam NYU Langone Test.

EKG Exam NYU Langone Test. 1. A delayed conduction of the AV node is manifested by a: a. prolonged PR interval b. widened QRS c. inverted P wave d. absence of a P wave 2. Which of the following waveforms represent the elec- trical event that should initiate ventricular contraction? a. prolonged PR interval QRS complex 3. What is the normal range of the PR interval? 0.12-0.20 4. What is the normal length of the QRS interval? below 0.12 5. What bpm rate is Sinus Tachycardia on a strip? 101-160 bpm 6. Which of the following describes a cells ability to spon- automaticity taneously generate an impulse? 7. Which node independently conducts a rate of 40-60 in AV node an adult patient? 8. Which node independently conducts a rate of 60-100 in an adult patient? SA node 'the pacemaker of the heart' 9. What does the T-wave represent? ventricle repolarization 10. What is the normal PQRS ratio? 1:1 11. What is the rate on a strip for sinus bradycardia? less than 60 bpm 12. How do you calculate the rate on a strip? multiply the number of QRS's by 10 13. How to differentiate between normal sinus rhythm and sinus arrhythmia 14. the activation of BLANK system causes in a release in *pay attention to marks on strip to count right* the distance between each R (peak in QRS wave) is dif- ferent and NOT the same within a strip sympathetic nervous sys- epinephrine which results in an increase in heart rate, tem blood pressure, and cardiac output 15. the QRS on an EKG corresponds to which of the follow- a. ventricular depolariza- ing electrical events: a. ventricular depolarization b. ventricular repolarization c. atrial repolarization d. atrial depolarization tion 16. Inefective atrial contractions are associated with which d. atrial fibrillation rhythm a. normal sinus with PAC b. normal sinus with PVC c. ventricular fibrillation d. atrial fibrillation 17. How can you tell a strip with normal sinus rhythm with The P wave comes EARLY. PAC (premature atrial contraction is occurring)? P waves occur when the atria contracts followed by the QRS and T waves. You know a PAC is occurring when the PQRST segment 18. Which of the following is a characteristic of atrial flut- ter? 19. When taking the pulse of a patient in atrial fibrillation the nurse would expect a. an irregular pulse and pulse deficit b. an irregular and bounding pulse c. a regular pulse and pulse deficit d. a regular and bounding pulse happens too soon after the last PQRST. tombstone pattern a. an irregular pulse and pulse deficit 20. In atrial flutter the atrial rate usually ranges between: 250 and 400 bpm 21. Which of the following would you expect to see in a patient with SVT at a ventricular rate of 220? a. hypotension b. hypertension c. headache d. pulse deficit a. hypotension What will NEVER be an answer on the test?
