RaDonda Vaught was sentenced to three years probation on a diverted sentence.
The case has focused attention on how nurses should be held accountable for medical errors.
RaDonda Vaught, 38, was convicted in March of criminally negligent homicide and abuse of an impaired patient after giving a fatal dose of the wrong medication to a 75-year-old woman.
Charlene Murphey died on December 27, 2017, in the intensive care unit of Vanderbilt University Medical Center after being injected with the incorrect drug.
Prosecutors claim Murphey was supposed to be given a sedative called Versed but was instead given vecuronium, which rendered her unable to breathe.
Meanwhile, nurses from across the country are rallying in her support and urging the judge not to sentence her to prison.
