just got woke up at 6:30am to have my blood pressure taken - it was probably a bit high as getting woke up in the wee hours tends top p*ss me off, ha, ha.
I was a nurse for many years, and I never really got why the "establishment" always wanted patients woken up early for their observations (obs) to be taken. OK, for critically ill patients, you need to take their obs very regularly for their own safety, as people can still die, or deteriorate a lot in their sleep. BUT for most patients, they are actually very stable, and would be much better off being left to get a couple of extra hours sleep, after being kept up in the night for several hours by snoring/shouting/crying/wailing Johhny in the next bed.
Its much more down to the tradition and routine being famliar for the nurses rather than anything else.
Truly, hospitals are the pits !! and I should know, as I have spent many, many years working in them. :(
