A nurse is reviewing the medication administration records from the previous shift. Which of the following findings should indicate to the nurse a need for an incident report?

Rationale: A. Extended-release (XL) formulations are designed to release the medication slowly over time. Crushing the tablet can result in the entire dose being released at once, potentially causing toxicity or adverse effects. This is a medication error that warrants an incident report to document the error and initiate system review to prevent recurrence. B. This may be unusual (heparin is typically given subcutaneously with a short needle, usually 25–27 gauge, ⅝–5/8 inch), but unless the client experienced harm, it is a procedural deviation that may require follow-up education but not necessarily an incident report. C. The vastus lateralis is a safe site for intramuscular injections in adults, though the ventrogluteal site is often preferred. This is not considered a sentinel or reportable incident. D. Gentamicin is sometimes administered as a short intermittent infusion, and giving it over 1 hour is generally acceptable depending on facility protocol. This is not a reportable error.
