Nursing staff need training

On sunday night 9 February i was in ward 1203c. I needed to get a drip. The sister came, see my drip was not into the vain anymore. She continue to connect the drip and even flushed the line right into the tissue. I had to call her back and demand that they stop the drip. When the nurse take it out she was so rude and rough. Thhey fo not have the knowledge or inclanation to treat their patients with care..
