Final answer:
A bystander may initiate the first step in a life-threatening emergency even without CPR/first aid certification, but being certified provides better ability to handle emergencies.
Step-by-step explanation:
A bystander may initiate the first step upon any life-threatening emergency even if the bystander does not have CPR/first aid certification. However, it is important to note that CPR and first aid certification trainings provide individuals with the knowledge and skills to effectively respond to emergencies. Certified individuals are trained to provide immediate care until professional help arrives, reducing the risk of further harm or complications. Without certification, the bystander may not have the necessary skills and may inadvertently exacerbate the situation or put themselves at risk.
