While there is no right or wrong answer to this question, your interviewers want to hear you speak with convincing passion as you answer this question. This question is an opportunity to give a unique answer that shows a quality you possess, so try to dig deeper than "strong attention to detail" or "strong communication skills." Some ideas you can consider discussing are extraordinary attention to detail (with an example of how you've shown these skills), the ability to walk a fine line between being empathetic and educational with patients, and top-notch manual dexterity skills.
