A dose was administered one hour before the scheduled time.

• A. Wrong Time
• B. Omission
• C. Wrong Dosage
• D. Unordered Drug

Answer: (A)

This item tests the Right Time aspect of medication administration. Giving a dose one hour before it’s scheduled is a timing error, because the administration time is part of ensuring medications achieve the expected effect and don’t interact with meals or other doses. The dose was delivered, so it isn’t an omission, and the amount and the drug itself aren’t in question here—just when it was given. That’s why this is a wrong time error.

The other possibilities describe different mistakes: not giving the dose at all would be an omission; giving too much or too little would be a wrong dosage; giving a drug that wasn’t prescribed or wasn’t in the order would be an unordered drug.
