Final answer:
Anna violated the right to record the medication after administration by documenting Mrs. Wilbur's antibiotic injection before she actually administered it, contravening the six rights of medication administration.
Step-by-step explanation:
Anna has violated the right to record the medication after administration, which is one of the six rights of medication administration. These rights include the right patient, right medication, right dose, right route, right time, and right documentation. By documenting the antibiotic injection before actually administering it, Anna deviated from proper protocol, which is to record after the medication is given.
This ensures that documentation is accurate and reflects the actual administration of the medication to the patient. In this case, Anna should have gone to Mrs. Wilbur's room, administered the injection, and then returned to the computer to document that the medication had been given. This practice helps to maintain patient safety and accurate medical records.
