What is the lower limit of the recommended adult chest-compression rate?
Complete the rhythm classifications: ventricular fibrillation and pulseless ventricular tachycardia are rhythms; asystole and pulseless electrical activity are rhythms.
After ROSC, what minimum MAP does the AHA recommend maintaining?
True or false: If a patient's chest discomfort improves after nitroglycerin, that confirms acute coronary syndrome.
- A
True
- B
False
A patient has persistent symptoms concerning for ACS, but the first 12-lead ECG is nondiagnostic. What is the most appropriate approach?
- A
Rule out ACS because the initial ECG is normal.
- B
Continue monitoring and reassessment, repeat the ECG if symptoms persist or change, and communicate the clinical concern.
- C
Wait for field biomarkers before deciding whether to transport.
- D
Give nitroglycerin repeatedly until the discomfort resolves, then stop evaluating for ACS.
During adult CPR with an advanced airway in place, continue compressions and deliver one ventilation every .
A patient has symptomatic bradycardia with hemodynamic compromise, and atropine has been ineffective. Which next step is appropriate to consider?
- A
Treat the heart rate number alone and observe without further support.
- B
Give verapamil to increase the heart rate.
- C
Consider transcutaneous pacing or an IV/IO rate-accelerating agent according to protocol.
- D
Use synchronized cardioversion as the routine next step.
A patient with tachycardia has hypotension and altered mental status consistent with poor perfusion. What is the priority rhythm treatment?
- A
Attempt vagal maneuvers and wait for a response before intervening.
- B
Perform prompt synchronized cardioversion.
- C
Give adenosine regardless of rhythm regularity or patient stability.
- D
Delay treatment until a 12-lead ECG and complete history are obtained.
For an adult in PEA, select all appropriate actions.
- A
Do not defibrillate PEA.
- B
Resume CPR immediately.
- C
Defibrillate before restarting CPR.
- D
Give epinephrine as soon as feasible, then every 3–5 minutes.
- E
Assess for reversible causes.
A patient has stable, regular, narrow-complex tachycardia. Which treatment sequence is appropriate to consider?
- A
Perform immediate unsynchronized defibrillation.
- B
Consider vagal maneuvers, then adenosine according to protocol.
- C
Give adenosine even if the rhythm is irregular or the patient is unstable.
- D
Use verapamil or diltiazem for any undifferentiated wide-complex rhythm.
After ROSC, select all appropriate care steps.
- A
Once oxygenation can be measured reliably, titrate oxygen to an SpO₂ of 90–98%.
- B
Give a routine rapid infusion of cold IV fluid for prehospital cooling.
- C
Avoid hypotension and maintain a minimum MAP of at least 65 mm Hg.
- D
Obtain a 12-lead ECG as soon as feasible.
A patient with acute respiratory distress and crackles has pulmonary edema and hypotension. Describe an appropriate prehospital approach, including how the hypotension affects treatment choices.
During adult cardiac arrest, an advanced airway is in place and compressions are continuous. How many seconds should pass between ventilations?
A patient has achieved ROSC. Once oxygenation can be measured reliably, which oxygen strategy best reflects the recommended post-resuscitation care?
- A
Keep inspired oxygen at its initial maximum level throughout transport.
- B
Titrate oxygen to target an SpO₂ of 90–98%.
- C
Reduce oxygen until the SpO₂ is below 90%.
- D
Avoid oxygen unless the patient becomes visibly cyanotic.
After ROSC, a patient remains hypotensive. What minimum mean arterial pressure (MAP), in mm Hg, does the AHA recommend maintaining?
A patient with symptomatic bradycardia remains poorly perfused after atropine. Which next approach is supported by the material?
- A
Repeat atropine indefinitely without reassessing perfusion.
- B
Give a fluid bolus to every patient with bradycardia.
- C
Consider transcutaneous pacing or an IV/IO rate-accelerating agent per protocol.
- D
Treat the heart rate number alone, regardless of symptoms or perfusion.
A patient has stable, regular, narrow-complex tachycardia with a pulse. Which initial treatment sequence is appropriate to consider?
- A
Consider vagal maneuvers, then adenosine per protocol.
- B
Perform immediate unsynchronized defibrillation.
- C
Give adenosine despite an irregular rhythm or instability.
- D
Use synchronized cardioversion as the first step in every stable case.
A patient with a pulse has an undifferentiated wide-complex tachycardia. Which approach is safest when the rhythm's origin is uncertain?
- A
Treat the rhythm as a stable narrow-complex tachycardia and give a calcium-channel blocker.
- B
Assume the rhythm is supraventricular unless the patient loses consciousness.
- C
Give verapamil to clarify whether the rhythm is ventricular.
- D
If uncertain, presume ventricular tachycardia and avoid verapamil or diltiazem for an undifferentiated wide-complex rhythm.
An adult in cardiac arrest has ventricular fibrillation, and the defibrillator’s manufacturer-recommended biphasic energy setting is unknown. True or false: Use the maximum available energy and deliver the shock promptly rather than delaying to find the recommended setting.
- A
True
- B
False
