Relias Assessments Assistance Material DYSRHYTHMIAS EKG interpretation One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart's electrical activity as waveforms. An EKG uses electrodes attached to the skin to detect electric current moving through the heart. These signals are transmitted to produce a record of cardiac activity. Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occurs as a result ...

What does each square of an ECG represent? 0.20 seconds. inside the box is smaller boxes that are 0.04 seconds of time. P wave first electrical signal saw. the atria is squeezing after receiving a signal from the SA node. The atrial kick is 20-30% of cardiac output. Loss of atrial kick will affect bp and pump performance Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:15 Full screen Brainpower Read More PR Interval SA (atrial) node dro...

WCU Pathophysiology 370 Final Exam Questions With Verified Answers Narcotic administration should be administered carefully in patients with acute pancreatitis related to potential for a. respiratory depression. b. narcotic dependency. c. sphincter of Oddi dysfunction. d. allergic reaction. - answerc. sphincter of Oddi dysfunction A patient is admitted to the hospital with left-sided heart failure. Which clinical manifestation would the nurse expect the client to exhibit? (Select all th...

Chapter 35: Dysrhythmias | Questions, Answers and Rationales A patient admitted with syncope has continuous ECG monitoring. An examination of the rhythm strip reveals the following: atrial rate 74 beats/min and regular; ventricular rate 62 beats/min and irregular; P wave normal shape; PR interval lengthens progressively until a P wave is not conducted; QRS normal shape. The priority nursing intervention would be to a. give epinephrine 1 mg IV push. b. prepare for synchronized cardioversion. c...

Dysrhythmia correct answer: Any disorder of the heart beat or heart rhythm. Cardiac output is impaired. Cellular oxygenation is then also impaired Electrical problem will definitely effect the mechanical but a mechanical problem may not effect the electrical. Explaining dysrhythmias correct answer: -Classified to their site of origin -SA node atrial tissue, AV node, junctional tissue (tissue around AV node), and ventricular tissue -Caused by a disturbance in impulse formation or b...

2nd degree block type II - Correct Answer-ECG strip that shows regular atrial rhythm, an atrial rate greater than ventricular rate (some QRS complexes are dropped) and a constant PR interval when the atrial and ventricular complexes appear together would most likely be identified as what rhythm? The ventricles are being stimulated during the relative refractory period - Correct Answer-Why is the R-on-T premature ventricular complex (PVC) of major concern? B. Multifocal premature ventricula...

Of the following, which would not be indicative of ventricular fibrillation? - Waves would be seen with every other complex The following would be indicative of ventricular fibrillation: No waves will be seen The QRS will be more than 120ms The rate will be 100-250 The patient will lose consciousness If a premature ventricular contraction (PVC) comes from different foci, they are referred to as which of the following? - Multifocal PVC's If the PVC's come from different foci, they woul...

PSG Boards Exam Prep What is Atrial Fibrillation? - In atrial fibrillation, the electrical activity of the heart is uncoordinated, with electricity traveling about the upper chambers in a chaotic fashion, causing the upper chambers to quiver (like a "bag of worms") and contract inefficiently or not at all. Common in elderly and those with heart disease. What is Atrial Flutter? - Atrial flutter causes a rapid but coordinated electrical stimulation of the upper chamber of the heart, of...

Which nursing intervention must a nurse perform when administering prescribed vasopressors to a client with a cardiac dysrhythmia? - Answer Monitor vital signs and cardiac rhythm Which ECG waveform characterizes conduction of an electrical impulse through the left ventricle? - Answer QRS complex Which is not likely origination point for cardiac dysrhythmias? - Answer Bundle of His The nurse is teaching a beginning EKG class to staff nurses. As the nurse begins to discuss the pa...
