Wait...she got her patients mixed up, gave another number of units-wrong dose then documented for the other...but management thinks she gave the wrong insulin.
Insulin is a "high alert med," hence the issue and the firing...Not sure if the Board will even get involved; HOWEVER, this is why "six rights" and triple checking, even with another person, is SO important.
I feel as though there is more to the story, of course...the patient may get a Regular/NPH protocol...if she was going to hold, she needed to call the provider. This patient may need her basal rate constant; holding the regular can rebound the patients sugar into a higher amount, resulting in a higher dose of Regular insulin.
She may have been fired for not collaborating with the provider, hence practicing our side her scope in some instances; and committing a med error, and error in documentation; delay in reporting if she didn't tell them immediately-this includes not even realizing that they made the med error.
I'm not sure whether she can or will be brought in front of the BON. The most your friend can do is review the nurse practice act, and if your friend had malpractice insurance
, to contact the insurance provider to answer her questions.
