Wisconsin ? A nurse charged with criminal negligence in a drug mix-up that led to the death of a 16-year-old pregnant girl was suspended Thursday for nine months, the state nursing board said.

Julie Thao, 42, was suspended retroactive to July 6, the day after the death of Jasmine Gant, an expectant mother whose 8-pound boy survived. The suspension will end in April.

Thao had agreed not to practice nursing while the Board of Nursing investigated. Her attorney, Stephen Hurley, said Thursday he did not know whether she wanted to return to nursing.

If she returned, her hours would be limited and she would face greater scrutiny from regulators for two years, the board said.

The board disciplined Thao for mistakenly giving Gant a dose of epidural instead of penicillin to treat a strep infection during labor. Epidural, a potent pain reliever used during childbirth, caused Gant to have a seizure and die within hours.
