The first nurse was unable to get the IV inserted, and she had to call over another nurse to try. As someone who dislikes getting an IV, this was upsetting. Please provide additional training to nurses who aren't comfortable or confident in putting in an IV.  Additionally, for female patients needing a breast MRI, please send in a female nurse to get them out of the machine. At the very least, consult with the patient as to whether they are comfortable with a male getting them and proceed accordingly.
