Emergency Nursing Orientation 3.0: Cardiovascular Emergencies Part I Part II (Questions and Answers)

Which intervention is used to treat a patient with ventricular fibrillation who has an implantable cardiac defibrillator? - Apply hands-free adhesive patches in the anterior-posterior position and defibrillate. Which dysrhythmia has an irregularly irregular ventricular response - Atrial fibrillation Which medication should be administered during the resuscitation of a patient with ventricular fibrillation? - Epinephrine (Adrenalin) Which disorder is likely to produce a delta wave on the cardiac monitor? - Wolff-Parkinson-White syndrome A preexcitation syndrome, such as Wolff-Parkinson-White syndrome, results from which conduction pattern? - Atrial impulses bypass the typical electrical pathway and activate the ventricular myocardium directly. A patient has stable, monomorphic ventricular tachycardia. To perform synchronized cardioversion with a biphasic defibrillator and convert this dysrhythmia, which energy setting should be used first? - 100 joules Which disorder can initiate atrial flutter? - Pulmonary embolism Which disorder is potentially reversible if the cause is immediately treated? - Pulseless electrical activity Which drug may be used to convert new-onset atrial fibrillation? - Amiodarone (Cordarone) An unstable patient with polymorphic ventricular tachycardia requires which electrical treatment with a biphasic defibrillator? - Defibrillation at 200 joules In the PAAS mnemonic for performing automated external defibrillation, what does the P stand for? - Power Pulse Which dysrhythmia results from the continuous stimulation of two conduction pathways in the atrioventricular node? - Atrial fibrillation In which dysrhythmia does an impulse originate in the atrioventricular junction before the next expected sinus impulse? - Premature junctional complex
