#3
Which rhythm is characterized by a regular, narrow-complex tachycardia in ACLS?
Atrial Fibrillation
ExplanationAtrial Fibrillation presents as a regular, narrow-complex tachycardia.
#4
What is the recommended compression rate during CPR for adults according to ACLS guidelines?
100-120 compressions per minute
ExplanationRecommended compression rate for adults: 100-120 compressions per minute.
#5
What is the recommended depth for chest compressions in infant CPR according to ACLS?
At least 1.5 fingers depth
ExplanationRecommended compression depth for infant CPR: at least 1.5 fingers depth.
#6
Which rhythm is characterized by chaotic, irregular electrical activity in ACLS?
Ventricular fibrillation
ExplanationVentricular fibrillation presents as chaotic, irregular electrical activity.
#7
Which rhythm is NOT shockable according to ACLS guidelines?
Asystole
ExplanationAsystole is a non-shockable rhythm characterized by a flatline.
#8
What is the correct compression-to-ventilation ratio during CPR for an adult?
30 compressions to 1 ventilation
ExplanationFor adult CPR, the ratio is 30 compressions to 1 ventilation.
#9
Which medication is commonly used for the treatment of stable supraventricular tachycardia (SVT) in ACLS?
Adenosine
ExplanationAdenosine is frequently used for stable SVT in ACLS.
#10
During ACLS, when should you reassess the patient's rhythm after defibrillation?
After 2 minutes of CPR
ExplanationReassess rhythm after 2 minutes of CPR following defibrillation.
#11
Which medication is commonly administered for symptomatic bradycardia in ACLS?
Atropine
ExplanationAtropine is often used for symptomatic bradycardia in ACLS.
#12
Which of the following is a common cause of pulseless electrical activity (PEA) in ACLS?

In ACLS, what is the recommended initial dose of epinephrine for cardiac arrest?
0.5 mg
ExplanationInitial epinephrine dose for cardiac arrest is 0.5 mg.
#14
What is the correct sequence of actions during the 'CAB' approach in ACLS?
Circulation, Breathing, Airway
ExplanationCAB sequence: Circulation first, then Breathing, and Airway.
#15
Which of the following is NOT a potential reversible cause of cardiac arrest according to ACLS guidelines?
Hyperkalemia
ExplanationHyperkalemia is not typically considered a reversible cause of cardiac arrest.
#16
What is the preferred method for establishing a definitive airway in unconscious patients during ACLS?
Endotracheal intubation
