Multiple choice — select the best answer

AThe compression rate must be reduced when depth falls below 2 inches
BShallow compressions cause excessive gastric inflation during rescue breathing
CCompressions below 2 inches risk rib fracture more than deeper compressions
DCompressions that are too shallow generate insufficient blood flow to vital organs

✓ Correct answer: D. Compressions that are too shallow generate insufficient blood flow to vital organs AHA BLS guidelines require adult compression depth of at least 2 inches (5 cm) because shallower compressions are associated with inadequate perfusion pressure and reduced survival rates.
