When faced with a medical mystery that could potentially harm her patients, nurse Diane Iverson didn't just expose the problem. She solved it.

Two years ago, a sprinkling of patients in the Outpatient Center’s urology clinic began experiencing unpleasant reactions after they came in for endoscopic procedures. Most clinicians involved assumed that a few odd symptoms here and there—hives, tightness in the chest—were simply isolated events connected to the patients’ anxiety about having their bladders examined for tumors.

Diane Iverson could have made the same assumption. But the veteran nurse had a nagging suspicion that ate away at her and compelled her to speak up. As the reactions became more frequent and serious—landing some patients in the emergency department—Iverson relentlessly followed a trail that would lead her to the source of the mysterious reactions. Little did she know that her pursuit would involve a leading medical product manufacturer and help put an end to a national problem. MORE
