In the emergency department R1's INR ratio was 7.13 ratio, and another dose of Phytonadione 2.5 mg. was administered to R1.On November 18, 2025 at 3:23 PM, V12 (LPN) said, on October 28, 2025 she notified V10 (Physician) of R1's INR result of 1.42. V12 continued to say she was not aware R1's INR result had been addressed earlier in the day by V9 (NP), or that V9 increased R1's Warfarin dose from 1 mg. to 2 mg. V12 entered the new order of Warfarin 4 mg. from V10 (Physician), without discontinuing the previous order of Warfarin 2 mg. V12 said, The doctor ordered Warfarin 4 mg. so that's what I entered into the computer.On November 17, 2025, at 12:53 PM, V2 (DON-Director of Nursing) said, R1's Warfarin 2 mg. order was never discontinued prior to each new order being obtained. This error resulted in R1 receiving an additional dose of Warfarin 2 mg. each day, on October 29, 30, 31, 2025, and November 1, and 2, 2025, with the scheduled doses of Warfarin. V2 continued to say, [R1's] INR results were becoming more and more elevated each day, until the point where we had to give Vitamin K to help clot her blood and eventually send her to the hospital. There were multiple mistakes made, and the nurses involved (V5, V6, V7, V8) were all terminated. They were terminated for falsification of documentation. They copied someone else's documentation and didn't look at the INR lab results. 2. The EMR shows R4 was admitted to the facility on [DATE].

If that is what he wanted the resident to receive, the nursing staff should have discontinued my 2 mg. order, but they did not. All along, I thought [R1] was on Warfarin 2 mg.

That would explain the elevated INR results. The inaccurate administration of the Warfarin caused [R1's] INR to rise to the level of 13.10, resulting in hospitalization and Vitamin K administration. V9 continued to say R4 should not have received a total of 11 milligrams of Warfarin on October 31, 2025, and R4's elevated INR result of 5.04 ratio on November 4, 2025 was a result of R4 receiving the incorrect dose of Warfarin.
