Registered blind
Ms Evans told the inquest: "It was very extreme circumstances and there was an error on my part and I'm really sorry, I will always be sorry."
The inquest was also told by a diabetes specialist and a pathologist who examined Mrs Thomas's body that it was likely the overdose led to her death, but they could not be 100% sure.
Ms Evans told the court that she was visiting Mrs Thomas as a favour to community nurses in another area on 2 June, 2007.
She said she did not know until just before she arrived at Mrs Thomas's house at midday that the purpose of the visit was to administer insulin.
Mrs Thomas was registered blind and could not inject herself.
Ms Evans said Mrs Thomas gave her an insulin "pen" which she had never used before as they used a syringe and needle where she normally worked.
She tried using three of the pens but could not get them to work, she said.
'Wanted to help'
Ms Evans said she thought she had an insulin syringe in the car, but on fetching it, she discovered it was a regular syringe, not one for insulin.
She said she converted the amount wrongly in her mind and injected Mrs Thomas four times with the syringe, but mistakenly gave 10 times the dose of 36 units.
The inquest heard she had administered hundreds of insulin injections in her nine months as a community nurse.
"I've gone back over it loads of times thinking why and I honestly don't know why," she said.
"I just wanted to help her. I just want to be a good nurse and help patients and do the best I can for that patient."
