You will only use rescue breathing if the person is unconscious and does not have a pulse. a. true b. false

I'm not entirely sure but I think this is true (?) because rescue breathing should only be used if any of the following happened to the victim: drowning, drug overdose, collapse due to breathing problems, an unresponsiveness in infants or children, an unconsciousness adult that isn't breathing normally, and if they are having prolonged cardiac arrest. 

Hope this helps! :)

The answer is true because when the person is not able to breath regularly then you have to use rescue breathing to save their life.

Sorry I’m not a good explainer!
