#1
Which rhythm is considered shockable in ACLS?
Ventricular fibrillation
ExplanationShockable rhythms, like ventricular fibrillation, require defibrillation to restore normal heart rhythm.
#2
What is the recommended depth for chest compressions in adult CPR during ACLS?
4-5 cm
ExplanationThe recommended depth for chest compressions in adult CPR during ACLS is 4-5 cm.
#3
What is the primary goal of defibrillation in ACLS?
To restore normal heart rhythm
ExplanationThe primary goal of defibrillation in ACLS is to restore a normal heart rhythm by stopping chaotic electrical activity.
#4
What is the primary goal of administering amiodarone in ACLS?
To stabilize cardiac rhythms
ExplanationThe primary goal of administering amiodarone in ACLS is to stabilize cardiac rhythms, especially in ventricular arrhythmias.
#5
What is the recommended rate of chest compressions per minute in adult CPR during ACLS?
100-120
ExplanationThe recommended rate of chest compressions per minute in adult CPR during ACLS is 100-120.
#6
What medication is typically used for initial pharmacological treatment of ventricular fibrillation in ACLS?
Epinephrine
ExplanationEpinephrine is the first-line medication for ventricular fibrillation in ACLS, aiming to enhance myocardial perfusion.
#7
During ACLS, which action should be taken first in managing a patient with suspected myocardial infarction?
Administer aspirin
ExplanationAdministering aspirin is the first step in managing a suspected myocardial infarction during ACLS, helping to reduce platelet aggregation.
#8
Which rhythm is treated with synchronized cardioversion in ACLS?
Supraventricular tachycardia
ExplanationSynchronized cardioversion is used for supraventricular tachycardia in ACLS to restore normal heart rhythm.
#9
What is the recommended compression-to-ventilation ratio for adult CPR during ACLS?
30:2
ExplanationThe recommended compression-to-ventilation ratio for adult CPR during ACLS is 30:2.
#10
Which medication is a common adjunctive therapy for stable narrow-complex supraventricular tachycardia (SVT) in ACLS?
Adenosine
ExplanationAdenosine is commonly used as an adjunctive therapy for stable narrow-complex SVT in ACLS to restore normal heart rhythm.
#11
Which drug is indicated as the first-line therapy for symptomatic bradycardia in ACLS?
Atropine
ExplanationAtropine is the first-line therapy for symptomatic bradycardia in ACLS, aiming to increase heart rate.
#12
What is the purpose of the H's and T's in ACLS algorithms?
To identify reversible causes of cardiac arrest
ExplanationH's and T's in ACLS help identify and address reversible causes of cardiac arrest, improving the chances of successful resuscitation.
#13
What is the purpose of waveform capnography during advanced airway management in ACLS?
To confirm endotracheal tube placement
ExplanationWaveform capnography is used in ACLS to confirm the correct placement of an endotracheal tube during advanced airway management.
#14
What is the primary goal of administering magnesium sulfate in ACLS?
To stabilize atrial fibrillation
ExplanationThe primary goal of administering magnesium sulfate in ACLS is to stabilize atrial fibrillation.
#15
In ACLS, what is the purpose of administering sodium bicarbonate?
To correct metabolic acidosis
ExplanationAdministering sodium bicarbonate in ACLS aims to correct metabolic acidosis.
#16
What is the purpose of administering vasopressin during ACLS?
To increase systemic vascular resistance
ExplanationAdministering vasopressin in ACLS aims to increase systemic vascular resistance, supporting blood pressure and perfusion.
