I have been an LPN for the past two years. I've been working as a nurse at an assisted living facility that specializes in dementia care. Last night I had an experience that I never encountered before! I had noticed earlier in the day that two of my residents- a male and a female were holding each other's hands and just walking around.... harmless companionship. These two have some mild form of dementia but not severe enough to show any slight cognition deficits. Anyhow- last night I went to the male's room to give him his hs pill, and he wasn't in his room so I thought maybe he was in her room watching tv. The door was locked (as sometimes the residents do lock their doors because of "wanderers"... no answer- so I unlocked the door (I have a master key for each room) and there they both were- butt naked on the couch- her legs around him! They both yelled "close the door and get out!!!"... so I did close the door. I wasn't sure what to do- between patient privacy, rules and regulations, between both having some form of dementia- would the family approve... was it anyone else's business? ...do you let them "finish" or does the nurse need to remove the male from the room? I waited a few minutes- knocked on her door- and had asked if so and so was in there... she said yes- I had asked if he could please come out so I could take him to his room to give him his meds.... he was finally dressed and she was in a shirt and underwear at that time. What would be the most appropriate action to take in this situation?
