Why is it important to use credible source as a student and as a healthcare professional?

If the source you are attempting to use is not credible, information may be false.
In healthcare there a lot of news articles over various diseases like ebola, west nile ect.
if you wish to get information on curing or treating a disease as such, it is best to use a credible source.
if you do however use a non-credible source, you may try to use the information given from the article and maybe try to treat an illness but possibly fail or make things worse.

sorry if my grammar isn't on point

Omit means cleave out .
