EMERGENCY NURSING ORIENTATION
3.0: CARDIOVASCULAR EMERGENCIES
PART I PART II. EXAM 2025 QUESTIONS
AND ANSWERS
Which intervention is used to treat a patient with ventricular fibrillation who has an
implantable cardiac defibrillator? - ANS Apply hands-free adhesive patches in the anterior-
posterior position and defibrillate.
Which dysrhythmia has an irregularly irregular ventricular response - ANS Atrial fibrillation
Which medication should be administered during the resuscitation of a patient with ventricular
fibrillation? - ANS Epinephrine (Adrenalin)
Which disorder is likely to produce a delta wave on the cardiac monitor? - ANS Wolff-
Parkinson-White syndrome
A preexcitation syndrome, such as Wolff-Parkinson-White syndrome, results from which
conduction pattern? - ANS 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? - ANS 100 joules
Which disorder can initiate atrial flutter? - ANS Pulmonary embolism

, Which disorder is potentially reversible if the cause is immediately treated? - ANS Pulseless
electrical activity
Which drug may be used to convert new-onset atrial fibrillation? - ANS Amiodarone
(Cordarone)
An unstable patient with polymorphic ventricular tachycardia requires which electrical
treatment with a biphasic defibrillator? - ANS Defibrillation at 200 joules
In the PAAS mnemonic for performing automated external defibrillation, what does the P stand
for? - ANS Power Pulse
Which dysrhythmia results from the continuous stimulation of two conduction pathways in the
atrioventricular node? - ANS Atrial fibrillation
In which dysrhythmia does an impulse originate in the atrioventricular junction before the next
expected sinus impulse? - ANS Premature junctional complex
In which dysrhythmia does a compensatory pause commonly occur? - ANS Premature
ventricular complex
Patients with which type of premature complexes require close monitoring? - ANS Multifocal
premature ventricular complexes
Which method delivers nonsynchronous energy to the myocardium? - ANS Defibrillation
In which dysrhythmia does the P wave disappear or occur just before or after the QRS complex?
- ANS Junctional escape rhythm
Which type of block causes one P wave to precede each QRS complex until a QRS complex is
dropped in a regular pattern? - ANS Second-degree atrioventricular block, type II
