Relias Dysrhythmia Basic Test Answers normal sinus rhythm heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute Sinus Arrhythmia Appearance is ALMOST NORMAL: Respiratory – Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) Sinus Bradycardia <60 normal sinus rhythm Sinus Tachycardia >100 (100-150) normal sinus rhythm Premature Atrial Contraction (PAC) Heart Rate: Depends on underlying rhythm ...

Describe treatment of dysrhythmias correct answer: To determine if treatment is necessary, assess the patient. Then ask the following questions: Is he or she experiencing signs and symptoms of decreased cardiac output? Is the dysrhythmia potentially life threatening? If the answer to either of these questions is yes, the patient will need to treatment for the dysrhythmia. ***WE WILL DISCUSS TREATMENTS OF DYSRHYTHMIAS BASED UPON CURRENT ACLS TREATMENT ALGORITHMS CLINICAL MANIFESTATIONS ...

ECCO questions and answers rated A+ 2023 A patient has a transcutaneous pacemaker. Which action should the nurse implement when a pacemaker spike occurs but is not followed by ventricular complex? Assess the heart rate Increase the mA Increase the mV Assess the ECG lead placement - correct answer Increase the mA A patient has a transvenous temporary pacemaker in place. Pacemaker spikes are noted on the ECG, but they are not followed by a P wave or QRS complex. Which is initially indica...

Scenario: A 38-year-old female is admitted to the emergency department after “feeling palpitations and almost fainting.” She states that this started a few hours ago and got progressively worse as she tried to get ready for work. The ECG reveals nonconducted P waves without progressive PR intervals. On conducted beats, the PR interval is constant, with a ratio of 3:1 (three P waves to one conducted QRS interval). The ventricular rate ranges from 50 to 60. The PR interval is slightly pro...

Advent Health EKG Questions and Answers Rated A Afib The impulse originates in the Atria • The Atrial rate is > 300 and unable to measure [N/A] • No discernable P waves - PRI & Atrial rhythm cannot be measured [N/A] • The Ventricular rhythm is irregular • QRS within normal limits • If the Ventricular rate is <100 the rhythm is controlled A-fib; if the Ventricular rate is > 100 the rhythm is uncontrolled A-fib • This is a chronic rhythm for some patients Treatment: controlle...

The ECG reveals nonconducted P waves without progressive PR intervals. On conducted beats, the PR interval is constant, with a ratio of 3:1 (three P waves to one conducted QRS interval). The ventricular rate ranges from 50 to 60. The PR interval is slightly prolong...
