WITH QUESTIONS AND ANSWERS 2025
UPDATE.
1. Q: Should chest compressions be delayed if the team does not agree on the rhythm
diagnosis during the pause at the end of a BLS cycle?
A: False. Chest compressions should not be delayed. Resumption of chest compressions should
not wait for team agreement on the rhythm diagnosis.
2. Q: What is a key difference between pulseless VT and PEA?
A: Pulseless VT is more reliably associated with a rate greater than 200 per minute, while
both rhythms show consistent ECG complexes but no palpable pulses.
3. Q: A 9-year-old Doberman Pinscher presents with weakness, cough, and lethargy. The
ECG shows wide complexes at 242 bpm, but the pulse rate is only 96 bpm. How would you
treat this dog?
A: Administer a slow IV bolus of lidocaine.
4. Q: After diagnosing ventricular fibrillation at the end of a BLS cycle, what is the correct
next step?
A: Immediately resume chest compressions and defibrillate again if the patient is still in VF at
the end of the next BLS cycle.
5. Q: Can the same dosing chart be used for both biphasic and monophasic defibrillators?
A: False. Biphasic defibrillators are more efficacious, but they require different dosing than
monophasic defibrillators.
6. Q: A patient has been in pulseless VT for multiple cycles of CPR. What additional
therapy would be useful?
A: Administer amiodarone IV as an additional therapy.
