How to answer: “Tell me about a mistake you made in patient care.”

What they’re actually asking

Every honest clinician has one, and hiding it is the worst possible move — healthcare runs on people who report their own errors. They're testing whether you own mistakes fast and loudly, because the nurse who hides a small error will eventually hide a big one.

How to structure your answer

Choose a real error with a contained outcome. Structure: what happened, what you did in the next five minutes (report it, protect the patient), what system or habit you changed so it can't recur. Ownership language throughout — no passive voice, no shared blame.

Example answer

“As a new nurse I hung an IV antibiotic thirty minutes early because I misread a handwritten update from the previous shift. I caught it while charting, told the charge nurse and pharmacy immediately, and we monitored the patient — no harm, but I didn't know that when I reported it, and that's the point. Since then I check every timing change against the MAR directly, never against handoff notes alone. I've caught two other people's timing errors that way since.”

What sinks people

• "I can't think of a mistake" — reads as either dishonest or dangerous
• Choosing a catastrophic story that overshadows the lesson
• Blaming the shift, the handoff, or the system before owning your part
