The nurse should have a Consent Agreement (CA) from TPAPN which spells out restrictions. The CAs we see in Ohio, Kentucky, and Indiana will list restrictions, monitoring requirements, reporting/paperwork requirements, etc. TXRN2's suggestion to contact TPAPN is a good one.
The numerous clients we have with the law office generally aren't permitted to supervise other nurses which sounds like they couldn't precept. The whole purpose for these contracts with specifications limiting things the nurse can do is to decrease the stress of re-entry to the workplace so the nurse can strengthen their recovery skills in the real world.
Some treatment facilities and monitoring programs rarely discuss the HALTSS acronym for relapse... H=Hungry, A=Angry, L=Lonelyy, T=Tired, S=Stressed, S=Sick. These are things that can increase the risk of relapse in a recovering addict. The more you have, the greater the risk. Hence the "no floating" (increased stress and "alone" time), no night shifts (less supervision more alone time, increased risk of fatigue and disrupted sleep time), no overtime (increased fatigue, increased stress, difficulty attending support groups, more time around cues and triggers). This is also why they restrict work environment during the reentry period. Most nurses aren't permitted to work in ERs, ICUs, home care, hospice care in the home, etc.
