suspended, what to do?

My husband got his LVN right at 9 months ago. His first job was an awful lct place; he left after 6 months, along with half the staff because the ratios went from 60:1 to 90:1. He got hired pretty quickly at a rehab facility as a treatment nurse, and while he enjoys and does well with the actual treatment part of his job, he's struggling with a lot of the supervisory stuff- he's not an ADON, he's not expirienced enough to be an ADON, but the ADONs took advantage and he's been doing a lot of staffing and reports that aren't really his responsibility. It's not effecting his job performance, but he's been in overtime most weeks and the brand new DON and he discussed it Monday, and he resolves to do better in the future, and they put some measures in place to help with that. Otherwise, they've been happy with him.

Then yesterday this happened; he was in a patient room and 2 aides came charging out of the room next door with the patient hollering about abuse. My husband was the nearest nurse, and he told the aides to immediately go tell the DON what happened. He then finished up the treatment he was doing, then went in and talked to the patient and did a head to toe assessment. He found nothing wrong, and the patient admitted that they didn't actually hurt her; she was just uncomfortable with men changing her diaper so threw a fit. He then reported it to the DON, who immediately told him to go home until the investigation was concluded and not to contact the facility until they called him.

He apparently should have escorted the aides to the DON rather than asses the patient, which, as a layperson, makes no sense to me. I also think that some on the spot retraining would've been enough, but there was a person from corporate in the office, so the DON said she had no choice. The ADON felt really sorry for him, and, incidentally, Monday (right after that talk about OT) they asked him to stay over to lead an investigation regarding a much more serious allegation (also false).

So do we start sending out resumes again or should he be back to work by the end of the week?
