Marilyn is a 41-year-old woman who presents for complaint of chronic diarrhea. She says she has had problems with her bowels as long as she can remember, but it's really getting to be a problem; more often she has the urge to have a bowel movement and does not have time to get to the bathroom. To pursue a diagnosis of irritable bowel syndrome, the NP would expect to find a history of:
a. Occasional blood in stool
b. Left lower quadrant pain
c. Anxiety disorder
d. Intermittent constipation
