Explanation:

Define medication error types

Using the Medication Error Classification knowledge point

• Wrong dose error: Dispensing or administering an incorrect strength, quantity, or dosage of the correct medication.
• Omission error: Failing to administer or dispense an ordered dose or required auxiliary label.
• Wrong packaging error: Dispensing the drug in an incorrect container type.
• Wrong patient error: Dispensing or administering the medication to someone other than the intended patient.

Evaluate the given options

• Omitting the auxiliary label on a prescription: This is a labeling or omission-related error, not a wrong dose error.
• Dispensing metformin 1,000 mg when the prescription was written for metformin 500 mg: This involves dispensing a strength (\(1,000\text{ mg}\)) that differs from the prescribed strength (\(500\text{ mg}\)), which is a classic wrong dose error.
• Dispensing the medication in the wrong container type: This is a packaging error.
• Dispensing the correct medication to the wrong patient: This is a wrong patient error.

Answer:

• Omitting the auxiliary label on a prescription
• Dispensing metformin 1,000 mg when the prescription was written for metformin 500 mg (Correct answer)
• Dispensing the medication in the wrong container type
• Dispensing the correct medication to the wrong patient
