A nurse accused of poisoning two elderly patients at Naas General Hospital told gardaí that she had given one of them an intra muscular injection of Serenase which she claimed had been prescribed for him.

The State pathologist has told a jury that an elderly man who was allegedly poisoned by a nurse died of heart failure that was not related to an injection he received from the accused.

A former colleague of a nurse charged with poisoning two patients has told a jury that she saw her "brutally dart" an injection into one of them before throwing water over him and threatening him.

A nurse has admitted at Dublin Circuit Criminal Court that she should have immediately reported her colleague to her superiors after she saw her use excessive force to inject an unprescribed drug to a patient.
