"Care in hospital"

My mum was sent to Hairmyers hospital with a suspected stroke. She was seen and told she required a CT scan. Bearing in mind she had just had a stroke, she was sent by herself to find the CT Scan. This when she had problems walking, felt very ill etc she described to me that she was bouncing from one wall to another! Also when she was discharged we were told she would have to come back later to collect the prescription. I called around 6pm to make sure it was ready and the answer was No. I was told someone would call me back. No return call, so again I phone at 8, a staff nurse in ward 2 (emergency receiving unit) advised I would need to wait until the next day to collect this prescription as the pharmacy was now closed. I reminded her the reason my mum was in there was due to a stroke and she had been advised that she should never be late or miss medication. After some back and forth it was agreed I could get the prescription that night at 10pm. 

So my questions are as follows:

Is it Normal to allow someone, who is suspected to have had a stroke, to find their way through a complicated hospital system by themselves to find the CT scan?

Why is it acceptable to the staff that the medication wouldn’t be ready until the next day, only when I insisted and was willing to drive up to the hospital (20 mile round trip) at 10 pm at night after numerous phone calls the prescription was given. This prescription is literally lifesaving for stroke victims, surely it should be a priority?

Thanks
