Elderly gent comes to surgery complaining that his wife is weeing all night and sleeping all day.... you guessed it , he was giving her her sleeping tablet in the morning and her diuretic at night. When I was a student nurse we had a patient who was very confused, he kept setting off for Monte Carlo with his squash bottle in one dressing gown pocket and his wash bag in the other. Us students had to follow him round the hopsital and take him back to the ward. This went on for 3 days and then he suddenly came out of it and started apologising to everybody in case he had been rude to them (which he hadn't ).Turns out he had got a bit forgetful and was taking his pain killer and sleeping tablet and then "remembering" to take them 1/2 later , and again, and again. Dr told him to forget about them and just have a glass of whisky before bed. Another time we lost a patient who was a bit paranoid in her confusioin and went wandering off. After a search of the hospital the police were called. They wanted to complete their missing person form- questions such as was she wearing a wedding ring?..... dunno, she's a little old lady in a nightie... She turned up about a mile away , spotted by people having a barbeque by the river! She was ok, thnk goodness (not tombstoning)- these things always seemed to occur when I was in charge of the ward on a late shift....
