Notes

Answers should reflect a daily average of the last 2 days.
For rectal bleeding, "large amount" describes blood present in most stools.
For number of stools, several small stools clustered over a short period of time should be considered as 1 stool, since this may be due to incomplete evacuation or tenesmus.
