Nurses often aren't commended enough for all they do, and one woman wanted to make sure the nurse who helped her mom gets the thanks she deserves. Megan Smith's mom Margaret has cancer and is getting treatment at Vanderbilt University Medical Center in Nashville, Tennessee. While dealing with the effects of too much anesthesia, nurse Olivia Neufelder sang a song about angels to comfort Margaret and stayed by her side. Margaret now calls Olivia her angel! All the best to Margaret and the Smith family; we'll be thinking of you.
