Question

question 35 (mandatory) (2.857 points) a compression-to-ventilation ratio of _ compressions for every _ breaths is optimal with each breath being delivered of 1 second and each causing chest rise. options: \10, 5\, \20, 2\, \30, 2\, \30, 5\

Explanation:

In cardiopulmonary resuscitation (CPR), the optimal compression - to - ventilation ratio for adults (and in many standard CPR protocols) is 30 compressions for every 2 breaths, with each breath being delivered over about 1 second to cause chest rise. So we analyze the options:

• Option "10, 5": This ratio is not the standard CPR compression - ventilation ratio.
• Option "20, 2": 20 compressions to 2 breaths is not the standard ratio.
• Option "30, 2": This matches the standard CPR compression - ventilation ratio where we give 30 chest compressions followed by 2 rescue breaths.
• Option "30, 5": 30 compressions to 5 breaths is not the standard ratio.

Answer:

C. "30, 2" (assuming the options are labeled A - D with A: "10, 5", B: "20, 2", C: "30, 2", D: "30, 5")
