Explanation:

If a delegator has confidence in their subordinates and believes a task will be performed correctly, they are more likely to delegate. Reasons nurses may be reluctant to delegate include their own lack of self-confidence, the desire to maintain authority, and getting trapped in the 'I can do it better myself' mindset. Therefore, 'confidence in subordinate' is the exception as it actually encourages delegation. The other choices are common barriers to delegation in healthcare settings.
