Question 1

Which waveform on an ETCO2 capnograph indicates a return of spontaneous circulation (ROSC) during CPR?

Accepted Answer

A sudden increase in ETCO2 to 35–45 mmHg

Answer

ROSC causes a sudden rise in ETCO2 to normal physiologic levels (35–45 mmHg) as pulmonary blood flow is restored.

Question 2

A biphasic defibrillator is preferred over a monophasic defibrillator primarily because:

Accepted Answer

It requires less energy while achieving equivalent or superior defibrillation success

Answer

Biphasic waveforms are effective at lower energy levels (120–200 J) compared to monophasic devices (360 J), reducing myocardial damage.

Question 3

During a post-cardiac arrest debriefing, reviewing which device's stored data provides the MOST objective CPR quality metrics?

Accepted Answer

Defibrillator's event summary report with CPR feedback data

Answer

Modern defibrillators record CPR metrics including compression rate, depth, fraction, and ventilation rate, enabling objective post-event debriefs.

Question 4

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?

Accepted Answer

Clinical decision support system (CDSS)

Answer

Clinical decision support systems analyze patient data (such as weight) and provide evidence-based recommendations to guide clinical actions.

Question 5

When pad placement is adjusted to the anteroposterior position for defibrillation, which patient scenario MOST justifies this change?

Accepted Answer

Patient with an implanted pacemaker or ICD

Answer

Anteroposterior pad placement is recommended when the patient has an implanted pacemaker or ICD to avoid placing pads directly over the device.
