Medical-Surgical Nursing Chapter 35: Dysrhythmias, Chapter 36: Nursing Management: Dysrhythmias, EAQ- Lewis Med Surg CH.36, Nursing Management: Dysrhythmias- Assessment of Cardiac Rhythms, Med-Sure Lewis Study Guide 100% SOLVED The patient has an electrocardiographic (ECG) tracing that is 50 beats/minute, the rhythm is regular, and there is a P wave before every QRS complex. The QRS has a normal shape and duration, and the PR interval is normal. What is your response? A. Administer atr...

CCT-CCI questions with correct answers On a cardiac rhythm strip, which of the following can determine if the patients heart rate is regular? The RR intervals being equal. The PP intervals being equal. The RR intervals being unequal. Both A and B Answer If the RR or PP intervals are not equal, then the rhythm is irregular. One of the most uncommon rhythms that is always unequal is atrial fibrillation. If the physician orders a treatment for a patient that is supposed to help prevent ...

Sinoatrial (SA) node the pacemaker; highly specialized, neurological tissue impeded in the wall of the right atrium; responsible for initiating electrical conduction of the heartbeat, causing the atria to contract and firing conduction of impulses to the AV node A cluster of specialized myocardial cells located high in the right atrium and adjacent to the superior vena cava AV node (atrioventricular node) The AV node is located in the interatrial septum close to the tricuspid valve. ...

Nurs 5315: Adv Patho Exam 3 Set 1 | Latest Version | 2024/2025 | Graded A+ **Describe the flow of blood through the heart.** **Blood flows from the body into the heart through the vena cavas, enters the right atrium, passes through the tricuspid valve into the right ventricle, exits via the pulmonic valve into the pulmonary artery, travels to the lungs, returns via the pulmonary veins to the left atrium, passes through the mitral valve into the left ventricle, exits via the aortic valve...

Third Degree Heart Block correct answer: Occurs when atrial impulses are completely blocked at the AV node and fail to reach the ventricle; atria and ventricles are controlled by different and independent pacemakers Third Degree Heart Block Causes correct answer: inferior or anteroseptal MI Third Degree Heart Block Clinical Manifestations correct answer: dizziness, syncope, fatigue, exercise intolerance, HF Third Degree Heart Block ECG Rate correct answer: atrial 60-100 bpm; ventric...

DAANCE: ALL MODULES EXAM STUDY GUIDE 2023/2024 LATEST Pulmonary artery - CORRECT ANSWER-One of two arteries that carry venous (oxygen poor) blood from heart to lungs What type of intubation is preferred with emesis with aspiration? - CORRECT ANSWER-ETT. LMA or combitube acceptable. What emergency would a cricothyrotomy typically be performed? - CORRECT ANSWER-Airway obstruction Atropine would be given in which emergency? - CORRECT ANSWER-Symptomatic bradycardia Adenosine would be ...

Accelerated Junctional: Rate: 60-100 Rhythm: Regular Pwave: before/after/absent - inverted PR: unknown QRS: Normal *** Fast junctional escape 2. Asystole: absence of contractions of the heart-Flat Line 3. Atrial fibrillation: rapid, random, ineffective contractions 4. Atrial Flutter: Rate:Atrial 250-350 Ventricular: 100 -175 P:Irregular or absent, often "saw tooth" QRS: Normal Conduction: AV Blo...

HEALTHSTREAM TELEMETRY & ECG EXAM 2023/2024 Mechanical & Electrical Activity - CORRECT ANSWER-- Correlation between the electrical and mechanical functions of the heart - Electrical activity stimulates the heart to contract - Electrocardiogram (ECG) show both functions - Electrical pulse= action potntial Cardiac Monitoring - CORRECT ANSWER-- Used to diagnose dysrhythmias, chamber enlargement, MI/myocardial ischemia, monitor effects of electrolyte imbalances of medication administrat...

Cardiac Rhythms and Dysrhythmias Part 4

Properties of Cardiac Cells - Answer • Four properties of heart cells that allow the conduction system to start an electrical impulse, send it through the heart tissue, and stimulate muscle contraction: 1.) Automaticity 2.) Excitability 3.) Conductivity 4.) Contractility Automaticity - Answer (Properties of Cardiac Cells) • The ability to initiate an impulse spontaneously & continuously Excitability - Answer (Properties of Cardiac Cells) • The ability to be electrically s...
