#1
Which rhythm is commonly associated with ventricular fibrillation (VF)?
Ventricular fibrillation
ExplanationVF is characterized by chaotic and irregular electrical activity in the heart.
#2
What is the recommended depth for chest compressions during CPR for adults?
2 inches (5 cm)
ExplanationRecommended depth for effective chest compressions during adult CPR.
#3
Which of the following is a reversible cause of cardiac arrest according to ACLS guidelines?
Hypoxia
ExplanationAddressing hypoxia is crucial in treating reversible causes of cardiac arrest.
#4
What is the preferred route of drug administration during cardiac arrest?
Intravenous (IV)
ExplanationIV route ensures rapid and reliable drug delivery during resuscitation.
#5
What is the recommended compression rate during high-quality CPR for adults?
100-120 compressions per minute
ExplanationThe optimal compression rate for effective adult CPR.
#6
What is the primary purpose of administering epinephrine during cardiac arrest?
To increase blood pressure
ExplanationEpinephrine is given to improve coronary and cerebral perfusion pressure.
#7
Which medication is commonly used to treat stable narrow-complex tachycardia?
Adenosine
ExplanationAdenosine is a first-line medication for converting stable tachycardia.
#8
Which of the following is a common sign of pulseless electrical activity (PEA)?
Regular heart rate with palpable pulse
ExplanationPEA is characterized by the absence of a detectable pulse despite organized electrical activity.
#9
What is the recommended initial dose of amiodarone for the treatment of ventricular fibrillation?
300 mg
ExplanationThe initial dose of amiodarone for ventricular fibrillation management.
#10
What is the recommended dose of atropine for the treatment of symptomatic bradycardia?
1 mg
ExplanationAtropine is administered in 1 mg doses for symptomatic bradycardia.
#11
What is the correct compression-to-ventilation ratio for adult CPR performed by a single rescuer?
30:2
ExplanationThe recommended ratio of chest compressions to ventilations in adult CPR.
#12
What is the first step in the ACLS algorithm for the management of adult cardiac arrest?
Check for responsiveness
ExplanationAssessing responsiveness is the initial step in ACLS algorithm.
#13
What is the recommended depth for chest compressions in pediatric CPR?
1.5 inches (4 cm)
ExplanationOptimal compression depth for effective chest compressions in pediatric CPR.
#14
Which rhythm is characterized by irregular, chaotic electrical activity on the ECG?
Ventricular fibrillation (VF)
ExplanationVF is identified by its irregular and chaotic ECG pattern.
#15
Which of the following is NOT a sign of cardiac tamponade?
Bradycardia
ExplanationBradycardia is not a typical sign of cardiac tamponade.
