Quote from Whispera
start by telling them what the boundaries are, telling them when they are inappropriate, and telling them what is appropriate.
Yes. Be clear and concise, such as "There will be no physical displays of affection." Then, reinforce those boundaries through repetition. When the boundary is breached, take the offending Patient to the side, and repeat the boundary and the offense. Avoid lecturing or talking down to the Patient. Speak in a volume a notch above a whisper. This conveys confidential concern. Request the assistance of the Patient: "Look, I need your help here- there are rules we all have to adhere to and I need you to be an example. Can you do that for me?" Just about everybody wants to help and be an example.
If the Patient has a devil-may-care attitude, or a if power play is sensed, another tact may be taken- Find out what the Patient wants and use that want as a bargaining tool. For example, a lot of Patients want discharged. "I'm going to show you the quickest way out of here" and then reinforce treatment and rule compliance. With difficult Patients, I've gone as far as to say, "Look, I can be your best friend or your biggest stumbling block. The choice is yours".
These are merely two general examples of techniques found to be successful in manipulating your media to achieve a desired result. Of course there are many nuances to such interventions which come with time and experience. If you'd like to discuss any specific circumstances, CanadianNurse, I'm game!
Best of luck to you!
