QUESTION 1
A 58-year-old patient suddenly collapses in a monitored hospital unit. The monitor
displays ventricular fibrillation. A pulse check confirms pulselessness. What is the most
,appropriate immediate intervention?
A. Administer epinephrine before attempting defibrillation.
B. Deliver an unsynchronized shock and immediately resume CPR.
C. Perform synchronized cardioversion followed by reassessment.
D. Administer amiodarone before initiating electrical therapy.
🔴 Correct Answer: B. Deliver an unsynchronized shock and immediately resume
CPR.
🔵 Explanation: Ventricular fibrillation is a shockable cardiac-arrest rhythm. Immediate
defibrillation should be followed by prompt resumption of high-quality CPR to minimize
interruptions in chest compressions.
QUESTION 2
During adult CPR, which finding most strongly indicates that chest compressions are
producing effective perfusion?
A. Increasing end-tidal carbon dioxide from 8 to 12 mm Hg
B. A palpable femoral pulse during every compression
C. A sudden sustained increase in end-tidal carbon dioxide
D. Oxygen saturation increasing to 100%
🔴 Correct Answer: C. A sudden sustained increase in end-tidal carbon dioxide
🔵 Explanation: A sudden sustained increase in ETCO₂ during CPR can indicate improved
pulmonary blood flow and may signal return of spontaneous circulation when
accompanied by other clinical evidence.
QUESTION 3
A resuscitation team is performing CPR on an adult with a cardiac arrest. The patient has
an advanced airway in place. Which ventilation strategy is most appropriate?
A. Two ventilations after every 30 compressions
B. One ventilation every 6 seconds with continuous compressions
C. One ventilation every 3 seconds with continuous compressions
D. Three ventilations after every 15 compressions
🔴 Correct Answer: B. One ventilation every 6 seconds with continuous compressions
🔵 Explanation: With an advanced airway during adult cardiac arrest, continuous chest
compressions are maintained while approximately one breath is delivered every 6 seconds.
QUESTION 4
A patient in cardiac arrest has an initial rhythm of ventricular fibrillation. After one
shock, CPR is resumed. The rhythm remains VF on the next rhythm check. Which
,medication is appropriate after additional defibrillation and CPR according to the
cardiac-arrest algorithm?
A. Atropine
B. Adenosine
C. Epinephrine
D. Diltiazem
🔴 Correct Answer: C. Epinephrine
🔵 Explanation: Epinephrine is administered during adult cardiac arrest according to the
ACLS algorithm and is repeated at appropriate intervals while CPR and rhythm-directed
therapy continue.
QUESTION 5
A patient remains in refractory VF despite high-quality CPR and repeated defibrillation.
Which antiarrhythmic is appropriate for shock-refractory VF/pulseless VT?
A. Amiodarone
B. Verapamil
C. Atropine
D. Digoxin
🔴 Correct Answer: A. Amiodarone
🔵 Explanation: Amiodarone is an accepted antiarrhythmic for adult VF or pulseless VT
that remains refractory to defibrillation and CPR.
QUESTION 6
During CPR, a team member notices that chest compressions are frequently interrupted
for pulse checks. What is the most important corrective action?
A. Increase the duration of each pulse check.
B. Limit interruptions and perform rhythm assessments efficiently.
C. Stop compressions whenever the monitor shows organized activity.
D. Perform a complete neurological examination every two minutes.
🔴 Correct Answer: B. Limit interruptions and perform rhythm assessments
efficiently.
🔵 Explanation: High-quality CPR requires minimizing interruptions in chest
compressions. Rhythm and pulse assessments should be brief and coordinated with the
resuscitation cycle.
QUESTION 7
, A patient with cardiac arrest has an organized electrical rhythm on the monitor but no
palpable pulse. Which rhythm category does this represent?
A. Ventricular fibrillation
B. Pulseless ventricular tachycardia
C. Pulseless electrical activity
D. Sinus tachycardia
🔴 Correct Answer: C. Pulseless electrical activity
🔵 Explanation: PEA is organized electrical activity without a detectable pulse. It is treated
as a nonshockable arrest while CPR, epinephrine, and identification of reversible causes
continue.
QUESTION 8
A patient in PEA arrest has persistent severe hypotension before arrest and a history of
massive gastrointestinal bleeding. Which reversible cause should receive particular
attention?
A. Hypovolemia
B. Hyperthermia
C. Tension pneumothorax
D. Coronary vasospasm
🔴 Correct Answer: A. Hypovolemia
🔵 Explanation: Severe blood loss can produce profound intravascular volume depletion
and PEA. Correcting hypovolemia is therefore a priority while standard resuscitation
continues.
QUESTION 9
Which intervention is most appropriate for a patient in asystolic cardiac arrest?
A. Immediate synchronized cardioversion
B. Immediate defibrillation
C. High-quality CPR and epinephrine while reversible causes are addressed
D. Adenosine followed by vagal maneuvers
🔴 Correct Answer: C. High-quality CPR and epinephrine while reversible causes are
addressed
🔵 Explanation: Asystole is a nonshockable rhythm. Management focuses on high-quality
CPR, epinephrine, and systematic evaluation for reversible causes.
