A Waconia nursing home employee failed to take necessary emergency actions to save the life of a resident who became unresponsive and soon died, then blamed the neglect on being "tired and not thinking clearly," according to a state investigation.

The staff member at the Good Samaritan Society's nursing home should have performed resuscitation efforts and called 911 when the resident fell ill, the state Department of Heath said in a report released Wednesday.

The resident had instructed in an "advance directive" that such immediate actions be taken in critical situations, the report added.

The report concluded that the employee's neglect was responsible for the resident's death. The staff member quickly resigned when being questioned by the facility's administrative nurse, the report added.

As is its practice, the Health Department did not reveal the identities of those involved, nor did it say when the neglect occurred.

However, the resident's family identified her as Luvern Z. Kraft, 85, of Mound. One of her sons, Steve Kraft, said his mother died April 21, 2012. There was no autopsy he said, leaving him to suspect she died "I suppose of heart failure."

According to the investigation:

Kraft became unresponsive while using the toilet. The staff member was called to the room, but did not initiate CPR or call 911.

The employee acknowledged to the administrative nurse that such actions should have been taken. However, the staff member "was tired and was not ... thinking clearly at the time of the incident," the report read.

No finding of neglect was issued against the nursing home. Its administrator, Rebecca Bollig, has yet to respond to a request for comment about the findings.
