"I think when you have to work with a new doctor, sometimes getting them to believe you and to get that you know what you're talking about is the hardest part at the end of the day," she said. "If they don't like you because you bugged them so much, if you got what you needed for your patient, who cares? I don't have to be liked by every single doctor in that hospital as long as I'm doing my job and I'm doing what's best for my patient."
Her no-nonsense attitude and lacerating wit can extend to dealing with patients, especially if they are ignoring doctor's orders.
In the most recent episode of "Boston Med," Grabowski lectured a student brought into the ER for alcohol poisoning, who pleaded with her to discharge him so he could finish an exam due that day.
She refused: "You almost died last night, so I don't care that you have an exam due, you should have thought of that before you went out and got so drunk you almost choked on your own vomit."
Grabowski's demanding ER schedule, working 12-hour shifts that can last into the wee hours of the morning, has made sustaining a romantic relationship tricky for her in the past. It's been difficult to find someone who understands her work life.
Dating within the hospital has its pitfalls too. The working atmosphere in the ER can be very intense, where sometimes instant connections are made between co-workers that don't last outside of the ER bay room.
"You would think work would be a great place to meet somebody, and it's tempting, too, because they go through the same things that you go through, they understand what's going on," she said. "But I've made the mistake of dating someone I worked with before, and it was disastrous in the end. It makes working together difficult."
Online dating didn't offer much of an alternative to finding "Mr. Right" either.
"My problem with the Match.com thing is that I'm too nice," she said. "I would probably wind up marrying the first person I went on a date with because I just wouldn't want to have to dump them."
But Grabowski remains hopeful about her love life and about finding the right person.
"I think when it happens it'll just happen," she said. "I'll be on a subway or something and I'll just meet somebody sitting next to me."
Next week on "Boston Med," Grabowski returns with a medical case that leaves her unsettled. Watch to find out more about her personal life and her hopes for the future.
