Four nurses are no longer allowed to practice after the state revoked their licenses in the second half of 2010.

The Minnesota Board of Nursing took action against 201 nurses in that time period. Actions against 43 of those were considered non-disciplinary. The board suspended 100 nurses and 37 had limits or conditions placed on their licenses.

The board licenses and regulates more than 109,000 nurses.

Following are the four people whose licenses were revoked. The board describes revocation as "the most stringent disciplinary action," under which a nurse shouldn't expect to get a license ever again.

Cristy J. Kintop, Brainerd

The board revoked Kintop's license after she notified them that she no longer intended to practice nursing due to "recurring problems with opiate addiction."

Her disciplinary order listed multiple drug diversions, job terminations, license disciplinary actions and chemical-dependency treatments over a 12-year period.

Last year, Kintop was terminated by her Mille Lacs area employer for diverting injectable hydromorphone. Three months later, she told the board she was done with nursing.

Trudi S. Nevala, a.k.a. Evans, St. Cloud

Nevala was terminated from a home health care agency in late 2008. Despite that, she began visiting one of the agency's clients and charging her to manage her prescriptions.

The client told Nevala she had hired a new agency to manage her prescriptions, but Nevala continued in that role and told the client not to tell her family. The agency noticed at least 142 pills, including oxycodone, were unaccounted for over a two-month period.

In April 2010, Nevala was convicted of wrongfully obtaining assistance/theft, a felony, for accepting $17,460 in overpayments from two public assistance programs.

Nicole J. Romosz, Rochester

While working at a Rochester health care facility for federal inmates, Romosz developed a sexual relationship with an inmate.

She also provided him with tobacco, wrote him letters and had contact with his mother.

In late 2007, when the facility became aware of the relationship, Romosz resigned. In 2009, she was convicted of a felony for abusive sexual contact with a ward.

Wesley H. Yaidoo, Champlin

Yaidoo, as owner of a business called Unique Health Care, submitted false claims to Medicaid for registered-nursing services.

In August 2009, Yaidoo pleaded guilty to three counts of felony theft by swindle. Several months later, he was convicted of a gross misdemeanor for theft by swindle.

He also worked as a nurse after his license had lapsed and owed a $700 fine when his license was revoked.
