1. What is the most common cause of sudden cardiac death?
A) Ventricular fibrillation
B) Asystole
C) Pulseless electrical activity
D) Atrial fibrillation
Answer: A
Rationale: Ventricular fibrillation is the most common cause of
sudden cardiac death and requires immediate defibrillation.
2. What is the recommended compression rate for adult
cardiopulmonary resuscitation?
A) 60 to 80 per minute
B) 100 to 120 per minute
C) 120 to 140 per minute
D) 80 to 100 per minute
,Answer: B
Rationale: The recommended compression rate is 100 to 120
per minute with a depth of at least 2 inches.
3. What is the recommended compression to ventilation ratio
for adult single rescuer cardiopulmonary resuscitation?
A) 15 to 2
B) 30 to 2
C) 5 to 1
D) 10 to 2
Answer: B
Rationale: The recommended compression to ventilation ratio
for adult single rescuer cardiopulmonary resuscitation is 30 to
2.
4. What is the first drug administered in cardiac arrest?
A) Epinephrine
B) Amiodarone
C) Lidocaine
D) Atropine
,Answer: A
Rationale: Epinephrine is the first drug administered in cardiac
arrest for its vasoconstrictive effects.
5. What is the recommended dose of epinephrine in cardiac
arrest?

B) 1 mg
C) 2 mg
D) 3 mg
Answer: B
Rationale: The recommended dose of epinephrine in cardiac
arrest is 1 mg every 3 to 5 minutes.
6. What is the treatment for ventricular fibrillation?
A) Defibrillation
B) Cardioversion
C) Pacing
D) Medications
Answer: A
, Rationale: Defibrillation is the treatment for ventricular
fibrillation.
7. What is the treatment for asystole?
A) Cardiopulmonary resuscitation and epinephrine
B) Defibrillation
C) Cardioversion
D) Pacing
Answer: A
Rationale: Asystole is treated with cardiopulmonary
resuscitation and epinephrine. Defibrillation is not effective for
asystole.
8. What is the treatment for pulseless electrical activity?
A) Cardiopulmonary resuscitation and epinephrine
B) Defibrillation
C) Cardioversion
D) Pacing
