Question 1

During a cardiac arrest, ETCO2 rises from 10 mmHg to 35 mmHg without a change in CPR technique. This indicates:

Accepted Answer

Return of spontaneous circulation

Answer

A sudden rise in ETCO2 to near-normal levels (35-45 mmHg) during resuscitation is a reliable indicator of return of spontaneous circulation.

Question 2

What is the maximum recommended depth of chest compressions for an adult patient?

Accepted Answer

2.4 inches

Answer

Current AHA guidelines recommend chest compressions of at least 2 inches but no more than 2.4 inches to optimize cardiac output and avoid injury.

Question 3

A patient requires needle decompression for tension pneumothorax. Which landmark is used for the traditional approach?

Accepted Answer

2nd intercostal space, midclavicular line

Answer

The traditional landmark for needle decompression is the 2nd intercostal space at the midclavicular line, inserted superior to the 3rd rib to avoid neurovascular structures.

Question 4

When applying a tourniquet for extremity hemorrhage, how far above the wound should it be placed?

Accepted Answer

2-3 inches proximal to the wound

Answer

Tourniquets should be applied 2-3 inches proximal to the wound to effectively occlude arterial flow while allowing room for placement and tightening.

Question 5

A glucometer reads 'HI' for a diabetic patient in altered mental status. This indicates blood glucose is:

Accepted Answer

Above the device's measurable range (>600 mg/dL)

Answer

'HI' on a glucometer indicates the blood glucose exceeds the device's upper measurable limit, typically above 600 mg/dL, suggesting severe hyperglycemia.
