Which waveform on an ETCO2 capnograph indicates a return of spontaneous circulation (ROSC) during CPR?
Answer: A sudden increase in ETCO2 to 35–45 mmHg
ROSC causes a sudden rise in ETCO2 to normal physiologic levels (35–45 mmHg) as pulmonary blood flow is restored.
A biphasic defibrillator is preferred over a monophasic defibrillator primarily because:
Answer: It requires less energy while achieving equivalent or superior defibrillation success
Biphasic waveforms are effective at lower energy levels (120–200 J) compared to monophasic devices (360 J), reducing myocardial damage.
During a post-cardiac arrest debriefing, reviewing which device's stored data provides the MOST objective CPR quality metrics?
Answer: Defibrillator's event summary report with CPR feedback data
Modern defibrillators record CPR metrics including compression rate, depth, fraction, and ventilation rate, enabling objective post-event debriefs.
A prehospital provider uses a tablet-based decision support app that recommends drug doses based on patient weight during a pediatric arrest. This tool BEST represents which category of digital health technology?
Answer: Clinical decision support system (CDSS)
Clinical decision support systems analyze patient data (such as weight) and provide evidence-based recommendations to guide clinical actions.
When pad placement is adjusted to the anteroposterior position for defibrillation, which patient scenario MOST justifies this change?
Answer: Patient with an implanted pacemaker or ICD
Anteroposterior pad placement is recommended when the patient has an implanted pacemaker or ICD to avoid placing pads directly over the device.
A wearable cardioverter-defibrillator (WCD) vest is MOST appropriate for which patient population?
Answer: Patients at temporary high risk for sudden cardiac death awaiting ICD implantation or recovery
The WCD provides external defibrillation capability for patients with transient high SCD risk, such as those with recent MI and low EF awaiting cardiac function reassessment.
Which digital tool MOST directly supports the 'Team Dynamics' goal of closed-loop communication during resuscitation?
Answer: A code clock displayed on the monitor
A prominently displayed code clock ensures all team members share the same time reference, reinforcing timed communication loops for drug administration and rhythm checks.
