#1
What is the first step in the ACLS algorithm for managing cardiac arrest?
Assess the patient's responsiveness
ExplanationAssessing responsiveness allows for immediate action based on the patient's condition.
#2
Which medication is commonly administered during ACLS for the management of ventricular fibrillation?
Amiodarone
ExplanationAmiodarone helps stabilize heart rhythm in ventricular fibrillation.
#3
What is the recommended compression rate during high-quality CPR for adult patients?
100-120 compressions per minute
ExplanationMaintaining a compression rate of 100-120 per minute optimizes blood flow during CPR.
#4
Which of the following is a reversible cause of cardiac arrest according to ACLS guidelines?
Hypothermia
ExplanationCorrecting hypothermia can restore cardiac function and reverse arrest.
#5
Which rhythm is characterized by wide QRS complexes and no discernible P waves on an ECG?
Ventricular tachycardia
ExplanationVentricular tachycardia presents with wide QRS complexes and is distinct from other rhythms.
#6
What is the recommended depth of chest compressions during high-quality CPR for adult patients?
4-5 cm
ExplanationA compression depth of 4-5 cm ensures adequate blood perfusion during CPR.
#7
Which medication is commonly used in ACLS for the management of symptomatic bradycardia?
Atropine
ExplanationAtropine increases heart rate and is useful in treating symptomatic bradycardia.
#8
What is the recommended dose of epinephrine during ACLS for the treatment of cardiac arrest in adults?
0.2 mg/kg
ExplanationEpinephrine bolsters circulation and supports vital functions during cardiac arrest.
#9
Which medication is indicated as a first-line treatment for stable narrow complex tachycardia in ACLS?
Adenosine
ExplanationAdenosine is effective in terminating reentrant supraventricular tachycardia.
#10
What is the recommended energy level for initial biphasic defibrillation in adults with ventricular fibrillation or pulseless ventricular tachycardia?
100-120 joules
ExplanationBiphasic defibrillation at 100-120 joules is effective in restoring normal heart rhythm.
#11
In ACLS, what is the correct sequence of actions during the initial assessment of a patient with suspected cardiac arrest?
Start CPR, assess breathing, check for a pulse, attach monitor/defibrillator
ExplanationThis sequence ensures prompt initiation of life-saving interventions.
#12
Which of the following rhythms is treated with unsynchronized cardioversion in ACLS?
Ventricular fibrillation
ExplanationUnsynchronized cardioversion is indicated for unstable ventricular fibrillation.
