Every nursing interview has it somewhere.
Tell me about a medication error or a near miss you were involved in.
Almost every nurse has one. Very few have ever described it to anyone who was not filling in a form.
Why it is hard
It is not a knowledge question. Chidi knew exactly what had happened — the wrong concentration, the second check that did not happen because the unit was short, the thirty seconds before she caught it herself.
The difficulty is that the honest answer requires you to say, out loud, to a stranger who is deciding whether to hire you: I did something that could have hurt someone.
You minimise. It gets described in a way where it was not really your fault, the unit was short-staffed, the pharmacy label was confusing. All of it true. All of it reads as someone who will not own things.
You over-explain. Four minutes of context before the actual event, because you are managing how the listener feels about you the whole way through.
Chidi did the second one.
The first time she said it out loud
She practised the night before a med-surg interview. Vera calls your phone; she asked it to be a nurse manager and to ask about a near miss.
Her first answer ran three and a half minutes and she never actually said what the error was. She talked about the staffing, the handover, the label. The interviewer asked, "So what happened with the medication?" and she realised she had told the whole story around the hole in the middle.
Second attempt: ninety seconds, and she got the event in.
Third: about a minute, and it came out in the order that works — what happened, what she did in the moment, who she told and when, what changed afterwards.
That last part was the bit she kept leaving out, and it is the part interviewers are listening for.
What good looks like
She landed on something close to this:
I drew up the wrong concentration during a night shift. I caught it during my own second check, before it reached the patient. I stopped, disposed of it, told the charge nurse straight away, and filed the report the same shift. What changed is that I don't do the second check while walking anymore. I do it standing still, at the cart, every time.
Forty seconds. No blame, no minimising, no four minutes of setup.
The staffing situation was still true and she did not mention it, because it was not what the question was for.
The wider version
This is not really about nursing.
Every field has a question like this — the deal you lost, the outage you caused, the decision you got wrong. The answer requires a kind of honesty that is hard to improvise, because your instincts in the moment are to protect yourself, and protecting yourself is exactly what scores badly.
You can be a good nurse and give a bad answer. You can also fix it in about fifteen minutes, the night before, by saying it out loud three times to something that does not react.
