#1
Which rhythm is considered shockable in cardiac arrest according to ACLS guidelines?
Ventricular fibrillation (VF)
ExplanationVentricular fibrillation is shockable because it involves chaotic electrical activity in the heart.
#2
Which of the following is NOT a reversible cause of cardiac arrest according to ACLS guidelines?
Hypertension
ExplanationHypertension is not a reversible cause; it's a condition that might contribute but isn't directly reversible during ACLS.
#3
Which rhythm is characterized by a regular, narrow QRS complex and a rapid heart rate above 150 beats per minute in ACLS?
Supraventricular tachycardia
ExplanationThis rhythm originates above the ventricles and typically does not require defibrillation.
#4
What is the recommended compression rate for adult CPR according to ACLS guidelines?
100-120 compressions per minute
ExplanationThis rate ensures adequate circulation and oxygenation.
#5
What is the recommended depth of chest compressions for pediatric CPR according to ACLS guidelines?
At least 1.5 inches (4 cm)
ExplanationThis depth ensures effective compression while minimizing the risk of injury in pediatric patients.
#6
What medication is commonly used in ACLS for the treatment of stable ventricular tachycardia?
Amiodarone
ExplanationAmiodarone is used due to its antiarrhythmic properties in stabilizing ventricular tachycardia.
#7
In ACLS, what is the recommended initial dose of epinephrine for adult cardiac arrest?
2 mg every 3-5 minutes
ExplanationEpinephrine at this dose helps in supporting blood pressure and heart function during cardiac arrest.
#8
What is the recommended compression to ventilation ratio for adult CPR in the ACLS guidelines?
30:2
ExplanationThis ratio indicates the sequence of 30 chest compressions followed by 2 rescue breaths during CPR.
#9
What is the recommended depth of chest compressions for adult CPR according to ACLS guidelines?
At least 2 inches (5 cm)
ExplanationThis depth ensures effective compression to circulate blood.
#10
Which medication is recommended for the management of symptomatic bradycardia with signs of poor perfusion in ACLS?
Atropine
ExplanationAtropine helps increase heart rate and improves perfusion.
#11
What is the recommended dose of atropine for symptomatic bradycardia in adult patients?
1 mg
ExplanationThis dose helps counteract bradycardia effectively.
#12
What does the term 'ROSC' stand for in the context of ACLS?
Return of Spontaneous Circulation
ExplanationROSC refers to the return of a pulse and spontaneous cardiac activity.
#13
Which of the following is NOT a component of the H's and T's reversible causes of cardiac arrest in ACLS?
Toxins
ExplanationWhile toxins can cause cardiac arrest, they are not explicitly listed as part of H's and T's.
#14
In ACLS, which medication is indicated for the treatment of stable narrow-complex supraventricular tachycardia (SVT)?
Adenosine
ExplanationAdenosine helps in diagnosing and treating SVT by slowing conduction through the AV node.
#15
What is the purpose of the 'C' component in the ABCDE approach to patient assessment in ACLS?
Assessing circulation
ExplanationCirculation assessment is crucial for identifying and managing cardiac arrest.
#16
What is the recommended dose of atropine for pediatric bradycardia in ACLS?
0.1 mg/kg
ExplanationThis dose helps increase heart rate effectively in pediatric patients with bradycardia.
