ABSTRACT
This study document brings together 150 carefully worded exam questions drawn from AHA ACLS
Final Exam Questions and Answers with Explanation (Latest 2026/2027, with the strongest
emphasis placed on Apply the ACLS Cardiac Arrest, Bradycardia, and Tachycardia algorithms to
complex patient scenarios with accuracy, Interpret ECG rhythms and 12-lead findings to guide
time-sensitive interventions in ACS and stroke, Demonstrate effective team dynamics, closed-loop
communication and and post-cardiac arrest care according to 2025 AHA standards. Every item
follows the wording style and level of reasoning you meet in the real paper, and each one is paired
with a clear rationale so the correct choice is never a guess. Work through the set at your own
pace, mark the questions that slow you down, then come back to them until the reasoning feels
automatic. Learners who revise this way walk into the exam room recognising the pattern behind
the questions instead of meeting them for the first time. Keep going - steady, honest practice is
what turns a difficult paper into a comfortable pass.

,Q1 APPLY THE ACLS CARDIAC ARREST, BRADYCARDIA, AND TACHYCARDIA ALGORITHMS
TO COMPLEX PATIENT SCENARIOS WITH ACCURACY
During CPR, which parameter best reflects optimal chest compression fraction?
A. Compression rate of 100-120/min
B. Compression depth of at least 2 inches
C. Minimizing interruptions to less than 10 seconds CORRECT
D. Allowing full chest recoil after each compression
RATIONALE: Chest compression fraction (CCF) is the proportion of time spent performing
compressions; a CCF >60% is targeted, achieved by minimizing pauses. Rate, depth, and recoil
are quality components but do not directly define CCF. Thus, minimizing interruptions is the best
indicator of optimal CCF.
Q2 APPLY THE ACLS CARDIAC ARREST, BRADYCARDIA, AND TACHYCARDIA ALGORITHMS
TO COMPLEX PATIENT SCENARIOS WITH ACCURACY
Which finding on waveform capnography most reliably confirms endotracheal
tube placement?
A. Presence of a sustained waveform with each breath CORRECT
B. A single large amplitude spike on insertion
C. Gradual rise in end-tidal CO2 over 30 seconds
D. Absence of any waveform after 5 breaths
RATIONALE: Continuous waveform capnography showing a sustained rectangular waveform
with each breath is the gold standard for confirming and monitoring endotracheal tube placement.
A single spike or absent waveform may indicate esophageal intubation or dislodgement. A
gradual rise may occur with ROSC but is not the primary confirmation method.

,Q3 APPLY THE ACLS CARDIAC ARREST, BRADYCARDIA, AND TACHYCARDIA ALGORITHMS
TO COMPLEX PATIENT SCENARIOS WITH ACCURACY
A patient has a wide-complex tachycardia with a regular rate of 180. Which drug is
first-line if stable?
A. Adenosine 6 mg IV push
B. Amiodarone 150 mg IV over 10 minutes CORRECT
C. Synchronized cardioversion at 100 J
D. Procainamide 20 mg/min IV infusion
RATIONALE: For stable wide-complex tachycardia (possible ventricular tachycardia),
amiodarone is the preferred antiarrhythmic per ACLS. Adenosine is ineffective for most
ventricular tachycardias and may cause harm. Synchronized cardioversion is reserved for
unstable patients, and procainamide is an alternative but not first-line.
Q4 APPLY THE ACLS CARDIAC ARREST, BRADYCARDIA, AND TACHYCARDIA ALGORITHMS
TO COMPLEX PATIENT SCENARIOS WITH ACCURACY
Which intervention is prioritized for a patient with suspected acute stroke and a
glucose level of 45 mg/dL?
A. Administer IV thrombolytic immediately
B. Correct hypoglycemia with dextrose CORRECT
C. Obtain noncontrast CT head urgently
D. Start aspirin 325 mg orally
RATIONALE: Hypoglycemia can mimic stroke and must be corrected before proceeding with
thrombolysis or further stroke workup. Administering thrombolytics or antiplatelets without
correcting glucose may worsen outcomes. CT is important but secondary to immediate glucose
correction.

, Q5 APPLY THE ACLS CARDIAC ARREST, BRADYCARDIA, AND TACHYCARDIA ALGORITHMS
TO COMPLEX PATIENT SCENARIOS WITH ACCURACY
During a cardiac arrest, which vasopressor is recommended and at what dose?
A. Epinephrine 1 mg IV/IO every 3-5 minutes CORRECT
B. Vasopressin 40 units IV once
C. Dopamine 5 mcg/kg/min infusion
D. Norepinephrine 0.1 mcg/kg/min infusion
RATIONALE: Epinephrine 1 mg IV/IO every 3-5 minutes is the standard vasopressor in ACLS
cardiac arrest. Vasopressin is no longer recommended as a replacement. Dopamine and
norepinephrine are not used in cardiac arrest algorithms.
Q6 APPLY THE ACLS CARDIAC ARREST, BRADYCARDIA, AND TACHYCARDIA ALGORITHMS
TO COMPLEX PATIENT SCENARIOS WITH ACCURACY
Which rhythm is most likely to respond to unsynchronized high-energy shock?
A. Sinus tachycardia
B. Ventricular fibrillation CORRECT
C. Atrial flutter
D. Monomorphic ventricular tachycardia with pulse
RATIONALE: Ventricular fibrillation is a shockable rhythm treated with unsynchronized
defibrillation. Sinus tachycardia and atrial flutter are not shockable in this context. Monomorphic
VT with a pulse may be treated with synchronized cardioversion if unstable.
