Your welcome.
Refusing to administer a lifesaving action is personal decision, up close, remember it forever, decision. Using a third person voice in your writing does not make it any less personal.
Do you believe that having Certification is protection from a lawsuit? If you incompetently administer CPR and kill someone you could possibly be sued with or without certification.
If your personal choice is to not administer lifesaving CPR, despite knowing how to do so, because you fear a lawsuit then that is your personal choice and you alone must judge if it was worth avoiding a theoretical lawsuit.
I believe that having and maintaining certification for CPR keeps an individual current on how to do the technique, which comes into play in the “knowing how to do so” portion of your response.
With regard to personal versus third person voice, being able to see potential or probable considerations that affect others’ decisions is a key aspect of learning to deal with and overcome such issues. Analysis of human beings cannot be properly performed using only one’s own perspective.
