During an AED analysis, a bystander accidentally touches the patient. What is the most likely consequence?
Answer: The bystander may receive part of the shock energy
Contact with the patient during AED analysis or shock delivery can result in the bystander receiving a portion of the electrical discharge.
When using a bag-mask device for a patient with suspected cervical spine injury, which airway maneuver is preferred?
Answer: Jaw thrust without head tilt
The jaw thrust maneuver opens the airway without moving the cervical spine, making it the preferred technique in suspected spinal injury.
What is the recommended energy dose for the SECOND defibrillation attempt with a biphasic AED when the first shock was delivered at 200 J?
Answer: 200 J or higher per manufacturer
For subsequent biphasic shocks, the same or higher energy level (per manufacturer specification) is recommended, typically ≥200 J.
Which finding on end-tidal CO2 (ETCO2) monitoring during CPR suggests the patient may have achieved ROSC?
Answer: ETCO2 suddenly rises above 40 mmHg
A sudden sustained rise in ETCO2 to ≥40 mmHg during CPR is a strong indicator of return of spontaneous circulation.
For an unresponsive adult in VF, how long should a single defibrillation attempt (shock + CPR) cycle last before re-analyzing rhythm?
Answer: 2 minutes of CPR then re-analyze
After each defibrillation attempt, 2 minutes (approximately 5 cycles) of high-quality CPR should be performed before rhythm re-analysis.
Which airway adjunct is most appropriate for a semiconscious patient with an intact gag reflex?
Answer: Nasopharyngeal airway (NPA)
The nasopharyngeal airway is tolerated in patients with a gag reflex, unlike the oropharyngeal airway which can induce vomiting in conscious patients.
AED pads should NOT be placed in which configuration?
Answer: Both pads on the left lateral chest wall
Placing both pads on the same side of the chest does not allow adequate current to pass through the heart, rendering defibrillation ineffective.
