Answer and explanation
Correct answer: D. At least 2 inches or 5 centimeters but not exceeding 2.4 inches or 6 centimeters
Answer: At least 2 inches or 5 centimeters but not exceeding 2.4 inches or 6 centimeters.
Why not the others: 1 to 1.5 inches is insufficient to generate adequate cardiac output and perfusion pressure; Depths exceeding 2.4 inches increase the risk of rib fractures, flail chest, and visceral injury; 0.5 inches provides no hemodynamic benefit.
