Answer

Brief Explanations:

  • Option A: Chest compressions should be at least 2 inches (about 5 cm) for adults, not between 2.5 - 3 inches.
  • Option B: The ratio is 30 compressions followed by 2 rescue breaths (for single - rescuer CPR in most cases, not 50:2).
  • Option C: The rate of chest compressions for CPR is 100 - 120 compressions per minute. 100 compressions per minute is within the acceptable range.
  • Option D: Elbows should be locked (not relaxed) during chest compressions to ensure effective force transfer.

Answer:

C. 100 compressions should be performed every minute.
