According to the MAR, was the Amoxicillin administered as ordered?

The determination that Amoxicillin was not administered as ordered can be based on specific discrepancies noted in the Medication Administration Record (MAR). In order to confirm that a medication was given correctly, one must compare the administration times, dosage, and frequency listed on the MAR against the physician's orders.

If any of these aspects do not align with the orders, or if the medication was omitted entirely, then it would be correct to state that it was not administered as ordered. This could mean that the medication was either missed, documented incorrectly, or not given at all, leading to potential risks to the patient's health.

In the context of the other choices: stating that it was administered correctly would imply there was a full compliance with all the prescribing details, while indicating that it was administered at different times could suggest a variation in the schedule that may or may not comply with doctor instructions. Mentioning missing data would indicate an inability to fully assess whether the medication was given as required, but in this case, it's clear that the administration did not occur as prescribed, hence the selection of this answer.
