Barry is 77years old, he has Type 2 diabetes which sometimes requires insulin, he has significant medical history and lower limb weakness following a stroke. Barry lives in Residential Aged Care. Barry has advised the RAC Facility and its staff verbally and in writing, that he does not want staff waking him in the morning to test his blood glucose levels. Barry justifies his request by explaining that he has trouble getting to sleep at night and enjoys sleeping in, he always eats breakfast late and believes early morning blood glucose testing is pointless. Barry has been awoken with a sharp sting on his toe at 0610 by a night shift nurse testing his blood glucose level. When questioned by Barry, the nurse advises him that she needed to test the blood glucose early as it was likely to be a busy morning and she was making sure it didn't get missed because some staff would be off that morning attending mandatory training.

Discuss the merits of the nurse's rationale for her care decisions with Barry that morning using relevant legal and ethical theory.
