Emergency Cardiovascular Care (ECC) Certification Exam — Questions and Answers

Question 1: Which calcium channel blocker is first-line for rate control in stable atrial fibrillation with rapid ventricular response?

Amlodipine
Nicardipine
Nifedipine
Verapamil or diltiazem (Correct answer)

Correct answer: Verapamil or diltiazem

Diltiazem or verapamil (IV) are preferred calcium channel blockers for rate control in stable atrial fibrillation or flutter.

Question 2: A patient with stable wide-complex tachycardia of uncertain origin should receive which drug with caution?

Procainamide
Adenosine
Lidocaine
Verapamil (Correct answer)

Correct answer: Verapamil

Verapamil (a calcium channel blocker) should be avoided or used with caution in wide-complex tachycardia because it can cause hemodynamic collapse if the rhythm is ventricular tachycardia.

Question 3: What is the importance of continuing education in ECC professional practice?

To fill time between client appointments
To justify higher fees
It is only required for new professionals
To maintain current knowledge, meet certification requirements, and adapt to evolving industry standards (Correct answer)

Correct answer: To maintain current knowledge, meet certification requirements, and adapt to evolving industry standards

Continuing education ensures professionals stay current with new developments, technologies, and best practices in their field while fulfilling certification renewal requirements and providing better service to clients.

Question 4: What is the clinical significance of transient ST elevation that spontaneously resolves and recurs (Prinzmetal variant angina) in risk stratification?

It only warrants treatment if troponin is elevated
It is benign and requires no further evaluation
It indicates coronary vasospasm and carries risk of VF and sudden death during episodes (Correct answer)
It is equivalent to chronic stable angina and managed identically

Correct answer: It indicates coronary vasospasm and carries risk of VF and sudden death during episodes

Prinzmetal (vasospastic) angina can cause transient total occlusion leading to ventricular arrhythmias and sudden cardiac death during spasm episodes.

Question 5: During ACLS, magnesium sulfate is specifically indicated for which rhythm?

Asystole
Ventricular fibrillation
Torsades de pointes (Correct answer)
Atrial flutter

Correct answer: Torsades de pointes

Magnesium sulfate (1–2 g IV/IO) is the treatment of choice for torsades de pointes (polymorphic VT with prolonged QT interval).

Question 6: When administering medications via endotracheal tube (ETT) during cardiac arrest, how should the dose be adjusted?

Use half the IV dose
Use the same dose as IV
Use 10 times the IV dose
Use 2–2.5 times the IV dose (Correct answer)

Correct answer: Use 2–2.5 times the IV dose

Endotracheal drug doses should be 2–2.5 times the IV dose, diluted in 5–10 mL of sterile water or normal saline, due to unreliable absorption.

Question 7: The correct route of administration for vasopressin during cardiac arrest is:

Intramuscular only
Endotracheal only
Subcutaneous only
IV or IO (Correct answer)

Correct answer: IV or IO

Vasopressin may be given IV or IO at 40 units to replace either the first or second dose of epinephrine, though current guidelines no longer preferentially recommend it.

Question 8: In ECC QI programs, what does 'no-flow time' refer to?

Duration with no chest compressions during cardiac arrest (Correct answer)
Time before the arrest was recognized
Period of post-arrest care without monitoring
Interval between defibrillation attempts

Correct answer: Duration with no chest compressions during cardiac arrest

No-flow time is the total duration during a cardiac arrest when chest compressions are not being delivered, which worsens outcomes.

Question 9: An ECC quality program implements a 'pit crew' resuscitation model. What is the PRIMARY QI benefit of this approach?

It eliminates the need for post-event debriefs
Pre-assigned roles reduce task confusion and compression interruptions (Correct answer)
It reduces the need for defibrillation
Fewer medications are required during resuscitation

Correct answer: Pre-assigned roles reduce task confusion and compression interruptions

Pre-assigned roles in a pit crew model minimize confusion, task overlap, and compression interruptions during resuscitation.

Question 10: In ECC practice, what is the purpose of a standard operating procedure (SOP)?

To create unnecessary paperwork
To document step-by-step instructions for routine tasks to ensure consistency and quality (Correct answer)
To restrict employee creativity
To satisfy management preferences only

Correct answer: To document step-by-step instructions for routine tasks to ensure consistency and quality

SOPs provide standardized, detailed instructions for routine operations, ensuring consistency, quality, efficiency, and safety regardless of which qualified individual performs the task.

Question 11: Adenosine is the drug of choice for terminating which arrhythmia?

Atrial fibrillation
Ventricular fibrillation
Third-degree AV block
Stable narrow-complex supraventricular tachycardia (Correct answer)

Correct answer: Stable narrow-complex supraventricular tachycardia

Adenosine is first-line treatment for stable, narrow-complex supraventricular tachycardia (SVT) due to its ability to transiently block AV node conduction.

Question 12: When stratifying chest pain patients with the Canadian ACS Risk Scoring system, which of the following is NOT a component?

Radiation to arm or shoulder
Age ≥65
Prior history of deep vein thrombosis (Correct answer)
Diaphoresis

Correct answer: Prior history of deep vein thrombosis

DVT history is not a component of the Canadian ACS Score; the tool uses age, diaphoresis, radiation patterns, and other ischemic features.

Question 13: For an unresponsive adult in VF, how long should a single defibrillation attempt (shock + CPR) cycle last before re-analyzing rhythm?

30 seconds of CPR then re-analyze
1 minute of CPR then re-analyze
2 minutes of CPR then re-analyze (Correct answer)
3 minutes of CPR then re-analyze

Correct answer: 2 minutes of CPR then re-analyze

After each defibrillation attempt, 2 minutes (approximately 5 cycles) of high-quality CPR should be performed before rhythm re-analysis.

Question 14: What is the primary concern with administering calcium gluconate before defibrillation in a hyperkalemic cardiac arrest?

It can trigger asystole
It prolongs the QT interval
It has no role and may delay defibrillation
It stabilizes the cardiac membrane to allow safer shock delivery (Correct answer)

Correct answer: It stabilizes the cardiac membrane to allow safer shock delivery

Calcium gluconate (or chloride) stabilizes the myocardial membrane potential in hyperkalemia, reducing the risk of arrhythmia and making defibrillation more effective.

Question 15: Which is the first-line vasopressor recommended during cardiac arrest in the AHA ECC guidelines?

Dopamine
Norepinephrine
Epinephrine (Correct answer)
Vasopressin

Correct answer: Epinephrine

Epinephrine 1 mg IV/IO every 3–5 minutes is the first-line vasopressor for cardiac arrest per AHA ECC guidelines.

Question 16: A paramedic administers epinephrine to a patient per off-line medical control protocols. If an adverse outcome occurs, which party bears primary legal responsibility?

The hospital that owns the ambulance
The state EMS licensing board
The paramedic acting independently
The medical director who authorized the protocol (Correct answer)

Correct answer: The medical director who authorized the protocol

The medical director bears primary legal responsibility for off-line protocols because paramedics act as extensions of the physician's license when following standing orders.

Question 17: When benchmarking STEMI reperfusion times, why must raw door-to-balloon times be adjusted before comparing hospitals?

To account for differences in EHR software
Because CMS requires statistical adjustment for all metrics
To control for case mix factors like transfer patients and off-hours presentations (Correct answer)
To eliminate outlier data points from the dataset

Correct answer: To control for case mix factors like transfer patients and off-hours presentations

Transfer patients and off-hours (nights/weekends) cases systematically inflate door-to-balloon times, so risk adjustment is needed for fair comparisons.

Question 18: In post-cardiac arrest care audit, 'favorable neurological outcome' is most commonly defined using which standardized scale?

NIHSS stroke scale
Modified Rankin Scale score 0-1 only
Cerebral Performance Category (CPC) score 1 or 2 (Correct answer)
Glasgow Coma Scale (GCS)

Correct answer: Cerebral Performance Category (CPC) score 1 or 2

CPC 1 (good cerebral performance) and CPC 2 (moderate disability but independent) together define 'favorable neurological outcome' in most ECC and resuscitation registries.

Question 19: Which document specifically outlines a patient's wishes about specific medical interventions (e.g., mechanical ventilation, artificial nutrition) rather than designating a decision-maker?

Advance beneficiary notice
Living will (Correct answer)
POLST form
Durable power of attorney for healthcare

Correct answer: Living will

A living will (also called an instructional directive) specifies the types of treatments a patient does or does not want under defined circumstances.

Question 20: A project coordinator is creating a post-resuscitation care protocol for an ICU. Which element is MOST essential to include during the planning phase?

A list of dietary restrictions for post-arrest patients
Guidelines for family visitation hours
Clear criteria and decision pathways for targeted temperature management (TTM) (Correct answer)
Billing codes for resuscitation procedures

Correct answer: Clear criteria and decision pathways for targeted temperature management (TTM)

Targeted temperature management (TTM) is a core evidence-based intervention in post-resuscitation care that requires predefined eligibility criteria and clinical pathways.

Question 21: An ECC provider who exaggerates their certifications to obtain a position is violating which professional standard?

Veracity (truthfulness) (Correct answer)
Justice
Non-maleficence
Fidelity

Correct answer: Veracity (truthfulness)

Veracity obligates healthcare professionals to be honest and truthful in all representations, including credentials and qualifications.

Question 22: After ROSC, a 12-lead ECG shows ST-elevation in leads II, III, and aVF. What is the recommended next step?

IV thrombolytics only
Admit to ICU without cath lab activation
Repeat ECG in 30 minutes
Emergent coronary angiography (Correct answer)

Correct answer: Emergent coronary angiography

ST-elevation after ROSC indicates likely STEMI and requires immediate coronary angiography regardless of neurological status.

Question 23: Which waveform on a pulmonary artery catheter tracing represents right ventricular pressure?

A waveform with systolic pressure 15-25 mmHg and diastolic pressure 0-8 mmHg (Correct answer)
A waveform with systolic pressure 15-25 mmHg and diastolic pressure 8-15 mmHg
A waveform with mean pressure 2-6 mmHg
A waveform with systolic pressure 100-140 mmHg and diastolic pressure 60-90 mmHg

Correct answer: A waveform with systolic pressure 15-25 mmHg and diastolic pressure 0-8 mmHg

Normal right ventricular pressure is 15-25 mmHg systolic and 0-8 mmHg diastolic, distinguishing it from pulmonary artery pressures which have higher diastolic values.

Question 24: What is the recommended energy dose for the SECOND defibrillation attempt with a biphasic AED when the first shock was delivered at 200 J?

360 J
100 J
150 J
200 J or higher per manufacturer (Correct answer)

Correct answer: 200 J or higher per manufacturer

For subsequent biphasic shocks, the same or higher energy level (per manufacturer specification) is recommended, typically ≥200 J.

Question 25: Which feature of modern AEDs provides real-time feedback to rescuers during CPR?

Automated shock delivery without pause
Automatic airway management guidance
Impedance-based chest compression depth and rate monitoring (Correct answer)
Continuous 12-lead ECG recording

Correct answer: Impedance-based chest compression depth and rate monitoring

Modern AEDs use transthoracic impedance sensing to detect chest compressions and provide real-time audio/visual feedback on depth and rate.

Question 26: On a central venous pressure waveform, the 'v' wave represents:

Atrial contraction
Tricuspid valve closure and isovolumetric contraction
Passive venous filling of the atrium during ventricular systole (Correct answer)
Atrial relaxation and tricuspid valve opening

Correct answer: Passive venous filling of the atrium during ventricular systole

The 'v' wave reflects passive filling of the right atrium from the venous system while the tricuspid valve is closed during ventricular systole.
