ACLS Certification Exam — Questions and Answers

Question 1: An ETCO2 value below 10 mmHg during ongoing CPR most likely indicates which of the following?

Excellent chest compression quality
Poor CPR quality or inadequate cardiac output (Correct answer)
Correct endotracheal tube placement
Hyperventilation by the provider

Correct answer: Poor CPR quality or inadequate cardiac output

ETCO2 below 10 mmHg reflects poor pulmonary blood flow due to inadequate cardiac output, signaling suboptimal CPR quality.

Question 2: What does SWOT analysis evaluate?

Standards, Warranties, Objectives, and Targets
Sales, Workers, Outputs, and Timelines
Systems, Workflows, Operations, and Technology
Strengths, Weaknesses, Opportunities, and Threats (Correct answer)

Correct answer: Strengths, Weaknesses, Opportunities, and Threats

SWOT analysis is a strategic planning framework that evaluates internal Strengths and Weaknesses and external Opportunities and Threats.

Question 3: For a patient with a mature tracheostomy in cardiac arrest, what is the first step in airway management?

Insert an oropharyngeal airway
Perform orotracheal intubation through the mouth
Attempt ventilation directly through the tracheostomy stoma (Correct answer)
Apply a face mask over the mouth and nose

Correct answer: Attempt ventilation directly through the tracheostomy stoma

Ventilation through a mature tracheostomy stoma provides the most direct access to the trachea and should be the first approach.

Question 4: What QTc duration is generally considered prolonged and at risk for torsades de pointes?

>400 ms
>600 ms
>360 ms
>500 ms (Correct answer)

Correct answer: >500 ms

A QTc >500 ms significantly increases the risk for torsades de pointes (TdP) and sudden cardiac death.

Question 5: Why is maintaining confidentiality important in record keeping?

Only because it is a legal requirement
To reduce the number of people who need training
To protect sensitive personal and professional information from unauthorized access (Correct answer)
To make file storage easier to manage

Correct answer: To protect sensitive personal and professional information from unauthorized access

Maintaining confidentiality in record keeping protects sensitive personal, medical, financial, and professional information from unauthorized access, maintaining trust and legal compliance.

Question 6: Which risk response strategy involves reducing the likelihood or impact of a risk?

Risk mitigation (Correct answer)
Risk escalation
Risk acceptance
Risk transfer

Correct answer: Risk mitigation

Risk mitigation involves taking proactive steps to reduce either the probability of a risk occurring or its potential impact if it does occur.

Question 7: When applying core principles in practice, what should be the first consideration?

Cost reduction opportunities
Safety and compliance with established standards (Correct answer)
Client entertainment preferences
Timeline acceleration

Correct answer: Safety and compliance with established standards

Safety and compliance with established standards must always be the primary consideration when applying professional principles.

Question 8: Which ECG pattern is associated with hyperkalemia and should prompt immediate intervention?

Short PR interval with delta wave
ST depression in lateral leads
Prolonged QT with U waves

Correct answer: Peaked (tall, narrow) T waves, widened QRS, flattened P waves

Hyperkalemia produces peaked T waves early, then PR prolongation, P wave flattening, wide QRS, and ultimately a sine-wave pattern that can degenerate into VF.

Question 9: Which lead is most useful for identifying P waves and distinguishing atrial arrhythmias in ACLS monitoring?

Lead II or V1 (Correct answer)
Lead aVL
Lead aVR
Lead I

Correct answer: Lead II or V1

Lead II provides the best visualization of P waves due to its alignment with the atrial vector, while V1 clearly shows flutter waves and retrograde P waves.

Question 10: What is the most effective leadership approach in professional settings?

Avoiding all conflict and difficult conversations
Delegating all decisions to the team without guidance
Adapting leadership style to the situation and team needs (Correct answer)
Using the same authoritative style for all situations

Correct answer: Adapting leadership style to the situation and team needs

Diltiazem or metoprolol (Correct answer)
Atropine
Amiodarone
Adenosine

Correct answer: Diltiazem or metoprolol

Beta-blockers (e.g., metoprolol) or calcium channel blockers (e.g., diltiazem) are used for rate control in stable AF with RVR.

Question 13: What distinguishes inherent risk from residual risk?

Inherent risk exists before controls; residual risk remains after controls are applied (Correct answer)
There is no meaningful difference between them
Inherent risk is internal; residual risk is external
Inherent risk is financial; residual risk is operational

Correct answer: Inherent risk exists before controls; residual risk remains after controls are applied

Inherent risk is the level of risk present before any controls are implemented, while residual risk is the level that remains after controls and mitigations are applied.

Question 14: Which calcium channel blocker is preferred for IV administration in stable supraventricular tachycardia per ACLS?

Verapamil (Correct answer)

Immediately defibrillate
Continue high-quality CPR and administer epinephrine (Correct answer)
Check for carotid pulse and stop CPR
Administer amiodarone 300 mg

Correct answer: Continue high-quality CPR and administer epinephrine

Asystole is a non-shockable rhythm; management is high-quality CPR, epinephrine every 3–5 minutes, and investigation of reversible causes.

Question 20: During CPR, a sudden and sustained rise in ETCO2 from 15 to 40 mmHg most likely indicates:

Return of spontaneous circulation (ROSC) (Correct answer)
Accidental hyperventilation
Correct ETT placement confirmation
Worsening cardiac output

Correct answer: Return of spontaneous circulation (ROSC)

A sudden sustained rise in ETCO2 is a reliable indicator of ROSC, as restored cardiac output delivers significantly more CO2 to the lungs.
