what is the most likely cause of frank blood in a 70 year old patients stool?
a) large bowel adenocarcinoma
b) hemorrhoids
c) diverticulitis
d) ulcerative colitis

Explanation:

Large bowel adenocarcinoma (colorectal cancer) is a common cause of frank blood in the stool, especially in older patients (like a 70 - year - old). Hemorrhoids are more common in younger adults and usually present with bright red blood on the toilet paper or dripping in the toilet. Diverticulitis often presents with abdominal pain, fever, and sometimes blood in the stool but is not as likely as colorectal cancer in this age group. Ulcerative colitis usually has a more chronic course with other symptoms like diarrhea, abdominal pain, and is more common in younger adults.

Answer:

a) large bowel adenocarcinoma
