Question 1

When using a bag-valve-mask (BVM) on an adult, what tidal volume should each ventilation deliver?

Accepted Answer

500-600 mL

Answer

Adult BVM ventilation should deliver approximately 500-600 mL tidal volume to produce visible chest rise without causing gastric inflation.

Question 2

A capnography waveform suddenly drops to near zero during CPR. What is the most likely cause?

Accepted Answer

Esophageal intubation

Answer

A sudden drop of end-tidal CO2 to near zero during CPR strongly suggests esophageal intubation, as the stomach produces little CO2.

Question 3

Which IV access site is preferred in cardiac arrest when peripheral IV cannot be established?

Accepted Answer

Intraosseous (IO) access

Answer

Intraosseous access is the preferred alternative when peripheral IV fails in cardiac arrest because it can be established rapidly and provides reliable drug delivery.

Question 4

A patient in respiratory failure has SpO2 of 88% on a non-rebreather mask at 15 LPM. What is the next best intervention?

Accepted Answer

Initiate CPAP or BiPAP

Answer

When a non-rebreather mask fails to maintain adequate oxygenation, positive pressure ventilation via CPAP or BiPAP is the next escalation step.

Question 5

The correct placement for anterior-posterior (AP) defibrillator pads is:

Accepted Answer

Center of sternum and left scapula

Answer

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.
