A patient has a fast, regular, narrow-complex rhythm, is alert, and has adequate blood pressure. What is the most appropriate initial approach?

A
Prepare for immediate synchronized cardioversion based on the rate alone.
B
Check for symptoms and underlying causes, monitor, and follow the stable tachycardia pathway.
C
Treat the rhythm as pulseless ventricular tachycardia.
D
Delay assessment until a 12-lead ECG has been completed and interpreted.

Before reviewing a 12-lead ECG for rhythm or ischemic changes, first confirm and patient identity.

True or false

False

A patient with bradycardia feels dizzy but has preserved perfusion and no hypotension, shock, altered mental status, ischemic discomfort, or acute heart failure. What is the best initial approach?

A
Initiate pacing immediately because any symptomatic low rate requires it.
B
Treat the rhythm as cardiac arrest and begin the defibrillation pathway.
C
Assess for reversible causes, monitor, and reassess for developing compromise.
D
Discontinue monitoring because blood pressure is currently preserved.

A patient has tachycardia with a pulse. Select all findings that indicate cardiopulmonary compromise and make urgent escalation important.

A
Hypotension
B
Acutely altered mental status
C
A fast rate without symptoms or other evidence of compromise
D
Signs of shock
E
Ischemic chest discomfort
F
A regular rhythm on the monitor
G
Acute heart failure

After return of spontaneous circulation, which actions are included in the post–cardiac arrest pathway? Select all that apply.

A
Stabilization
B
Routine defibrillation regardless of the patient's rhythm
C
A 12-lead ECG
D
Automatic emergency coronary intervention for every patient
E
Consideration of emergency coronary intervention when indicated

A patient's symptoms and 12-lead findings suggest acute coronary occlusion. What is the most appropriate initial system-level action?

A
Wait for a second ECG before notifying anyone, even if the patient is unstable.
B
Promptly activate the local STEMI or reperfusion pathway and coordinate with the receiving or interventional team.
C
Use a single ECG feature to select a destination without considering local systems or clinician authority.
D
Continue routine observation because ECG findings cannot support escalation.

1 point

A patient with a pulse has stable tachycardia with a wide QRS. Which approach best reflects the recommended initial assessment?

A
Treat every wide-complex rhythm as pulseless ventricular tachycardia, even when a pulse is present.
B
Select a protocol based only on the rate, without considering QRS width or regularity.
C
Assume a wide-complex rhythm is harmless if the patient is currently stable.
D
Classify the QRS width and rhythm regularity, and use particular caution with expert consultation.

After an intervention for a potentially unstable rhythm, describe what you should reassess, what changes should prompt renewed escalation, and what key information should be documented.

True or false

An adult has an organized electrical rhythm on the monitor but no palpable pulse. The rhythm is shockable and should be treated with defibrillation.

A
True
B
False

An adult with bradycardia reports dizziness, but blood pressure and other signs of perfusion are preserved. What is the most appropriate initial approach?

A
Prepare for immediate pacing because any dizziness with bradycardia establishes poor perfusion.
B
Assess for reversible causes, monitor, and reassess; escalate if compromise develops.
C
Treat the ECG rate alone as proof that the bradycardia is causing cardiopulmonary compromise.
D
Stop monitoring unless the patient becomes unresponsive.

An adult has a fast, regular, narrow-complex rhythm with a pulse, is alert, and has adequate blood pressure. What is the best initial approach?

A
Proceed directly to synchronized cardioversion because the rhythm is fast.
B
Treat the monitor label as sufficient to determine the cause and treatment.
C
Assess symptoms and underlying causes, monitor, and follow the stable tachycardia pathway.
D
Ignore the rhythm unless the patient loses consciousness.

An adult has ongoing chest discomfort, but the first ECG is nondiagnostic. Which response is most appropriate?

A
Conclude that ACS is excluded and stop monitoring.
B
Wait for a diagnostic ECG before taking any further action.
C
Repeat the same interpretation without reassessing the patient's symptoms.
D
Continue assessment and monitoring, arrange repeat ECGs and further ACS evaluation as indicated, and escalate if symptoms persist or instability develops.

An adult's symptoms and 12-lead ECG findings suggest acute coronary occlusion. What is the most appropriate initial system-level action?

A
Promptly activate the local STEMI or reperfusion pathway and coordinate with the appropriate team.
B
Wait for a single ECG feature to dictate the full treatment and transfer plan.
C
Delay notification until every possible test has been completed.
D
Choose a destination and reperfusion plan without regard to regional systems or clinician authority.
