When using a bag-valve-mask (BVM) on an adult, what tidal volume should each ventilation deliver?
Answer: 500-600 mL
Adult BVM ventilation should deliver approximately 500-600 mL tidal volume to produce visible chest rise without causing gastric inflation.
A capnography waveform suddenly drops to near zero during CPR. What is the most likely cause?
Answer: Esophageal intubation
A sudden drop of end-tidal CO2 to near zero during CPR strongly suggests esophageal intubation, as the stomach produces little CO2.
Which IV access site is preferred in cardiac arrest when peripheral IV cannot be established?
Answer: Intraosseous (IO) access
Intraosseous access is the preferred alternative when peripheral IV fails in cardiac arrest because it can be established rapidly and provides reliable drug delivery.
A patient in respiratory failure has SpO2 of 88% on a non-rebreather mask at 15 LPM. What is the next best intervention?
Answer: Initiate CPAP or BiPAP
When a non-rebreather mask fails to maintain adequate oxygenation, positive pressure ventilation via CPAP or BiPAP is the next escalation step.
The correct placement for anterior-posterior (AP) defibrillator pads is:
Answer: Center of sternum and left scapula
AP pad placement positions one pad on the center of the sternum (anterior) and the other on the left scapula (posterior), which is recommended for atrial fibrillation cardioversion.
Which finding on a pulse oximeter waveform indicates a reliable SpO2 reading?
Answer: Consistent pulsatile waveform matching heart rate
A consistent pulsatile plethysmographic waveform that correlates with the patient's heart rate indicates reliable pulse oximetry signal quality.
When preparing a stretcher-bound patient for air medical transport, which action is most important regarding IV lines?
Answer: Switch to saline locks and secure all lines
All IV lines should be converted to saline locks or secured with loop management to prevent accidental dislodgement during air transport loading and turbulence.
