Which medication error poses the highest risk to patient safety?
Asked on Nov 03, 2025
Answer
Medication errors can significantly impact patient safety, with wrong-dose errors posing one of the highest risks due to the potential for severe adverse effects or toxicity. Ensuring accurate dosing is critical, particularly with high-alert medications like anticoagulants, insulin, and opioids.
Example Concept: Wrong-dose errors occur when a patient receives a medication dose that is higher or lower than prescribed, potentially leading to harmful effects. This risk is heightened with medications that have a narrow therapeutic index, where the margin between therapeutic and toxic doses is small. Implementing the "Five Rights" of medication administration (right patient, right medication, right dose, right route, right time) is essential to prevent such errors and ensure patient safety.
Additional Comment:
- Always verify medication orders and calculations, especially for pediatric and geriatric patients.
- Use technology like barcoding and electronic health records to reduce errors.
- Educate patients about their medications to involve them in safety checks.
- Prioritize double-checking high-alert medications with another nurse.
- Report and analyze medication errors to prevent future occurrences.
