I can't find the thread of the accidental deaths in a hospital but just read this today.

A student nurse in Brazil badly botched an intravenous drip when she accidentally injected coffee into her patient. Unfortunately, there was nothing that could be done for the elderly woman who suffered when the milky coffee went straight to her vital organs.

According to Medical Daily, 23-year-old Rejane Moreira Telles had only three days of work experience when she attempted the intravenous feed. "Anyone can get confused," Telles stated on Brazilian TV. "I injected the coffee and I put it in the wrong place." What was Telles' explanation for getting confused? She mixed up the drip and the coffee because they were sitting next to each other.
