The California Board of Registered Nursing has taken the following actions against nurses featured in an ongoing series of stories by the nonprofit news organization ProPublica and The Times:
* Suspended the license of Owen Jay Murphy Jr. in August. He had been accused of physically and verbally assaulting patients at three Southern California hospitals. The board had allowed him to continue practicing while it pursued allegations, but regulators changed course after a July article.
* Revoked the license of Wilma Walker in October. She was fired by Martin Luther King Jr./Drew Medical Center in June 2005 because she allegedly failed to check a critically ill patient's heart-rate monitor. She was accused of charting the patient's vital signs at a time when he was, in fact, dead.
* Accepted the surrender of Dorothy Wilson's license in August. In 1999, the California Board of Podiatric Medicine put her on five years' probation for repeated acts of negligence. The following year, as a nurse handling anesthesia during a breast enlargement operation, Wilson did not notice that the patient had stopped breathing, according to filings in a subsequent malpractice suit against Wilson and the surgeon.
