A nurse who gave someone else’s medication to a patient in a care facility without a prescription has pleaded guilty to multiple felony charges.

Savannah L. Martin, 30, Youngsville, entered the plea Thursday to charges of possession with intent to deliver and neglect of a care dependent person.

The state Attorney General’s office brought the charges.

An employee at Cambridge, where Martin was employed as an LPN, told investigators that Martin had been “mislabeling and reissuing controlled substances,” according to the affidavit of probable cause.

The agent interviewed other employees at Cambridge, who said Martin had told them the patient had been prescribed morphine, that she had a verbal order from the doctor, had shown them how much to administer, and instructed them to administer the medication to the patient, according to the affidavit.

The medication was provided to the patient approximately nine times between Nov. 28 and Nov. 30.

Employees told investigators that the medication was given from a bottle with the patient’s name hand-written on it and the name of another patient — who had been prescribed Roxanol and later died — scratched out, according to the affidavit.

Police spoke with a former Cambridge administrator who said the patient was in late stages of life and the patient’s health was declining, according to the affidavit. She began the process of having the patient placed into hospice care, but “she passed away so quickly and was never placed on hospice care,” she told investigators.

She “reported she believed (the patient) passed away so quickly because (the patient) was being given morphine that (the patient) was not supposed to receive and was not prescribed,” according to the affidavit. She said the patient’s “death was accelerated due to Savannah Martin.”

The former administrator told investigators that, when confronted, Martin told her the patient “needed it and hospice wasn’t getting it here fast enough” and “didn’t care and would do it again, that she contacted the family, (the doctor), and hospice care and they were all on board with her doing this.”

Investigators interviewed Martin in September. She told them she had been terminated from her employment at Cambridge in December.

She told investigators that, when she told the doctor that the patient had taken a turn for the worse and that hospice was not available for three days, the doctor told her to “go ahead and start administering the Roxanol” from the deceased patient.

Martin told investigators she had the order for the Roxanol prescription at home, according to the affidavit.

“I would do it again,” she said, according to the affidavit. “I don’t care. I didn’t wrongfully medicate somebody. Was it originally prescribed to (the patient)? No. Was it the same medication? Absolutely. Did I hinder (the patient’s) health? No. But I wasn’t going to let (the patient) suffer and I would do it all over again.”

In exchange for the plea, nine counts of possession with intent to deliver, recklessly endangering another person and theft by unlawful taking were not prosecuted.
