Answer:
What contributed to the medication error was that the nurse did not check the patient's INR before applying the medication.
Explanation:
Medication errors occur when someone in the medical team fails to evaluate a factor and ends up passing a medication that could not be consumed or applied in the presence of that factor. In the case presented in the video, mentioned in the question above, the patient had a very high INR, in this situation the medication known as Coumadin could not be applied, as it could cause abnormal bleeding and it was difficult to control. However, the nurse did not check the level of INR that the patient was presenting before applying the medication.
