Question 1

A patient, who first developed acute diarrhea 2 weeks ago, presents to clinic reporting profuse watery, bloody diarrheal stools 6 to 8 times daily. The provider notes a toxic appearance with moderate dehydration. Which test is indicated to diagnose this problem?

A) Qualitative and quantitative fecal fat
B) Stool collection for 24-hour stool pH
C) Stool sample for C. difficile toxin
D) Wright stain of stool for white blood cells

C

Accepted Answer

The presentation of bloody, watery diarrheal stools is suggestive of an infectious process, and Clostridium difficile is a common culprit. Therefore, a stool sample for C. difficile toxin testing is indicated. Qualitative and quantitative fecal fat testing is used to diagnose malabsorption disorders. Stool collection for 24-hour stool pH is used to diagnose bile acid malabsorption. Wright stain of stool for white blood cells may suggest inflammatory bowel disease but is not specific for any particular diagnosis.

Question 2

Which types of chronic noninfectious diarrhea will cause fatty stools? (Select all that apply.)&#10;A) Celiac disease&#10;B) Cystic fibrosis&#10;C) Diabetes mellitus&#10;D) Lactose intolerance&#10;E) Pancreatic insufficiency

Accepted Answer

Celiac disease, cystic fibrosis, and pancreatic insufficiency can all cause malabsorption of fat, leading to fatty stools. Diabetes mellitus and lactose intolerance do not typically result in fatty stools.

Question 3

A patient who developed chronic diarrhea after gastric surgery asks what can be done to mitigate symptoms. What will the provider recommend initially?&#10;A) A diet high in carbohydrates&#10;B) Avoiding liquids with meals&#10;C) Empirical antibiotic therapy&#10;D) Probiotic supplements

Accepted Answer

Avoiding liquids with meals is often recommended initially to help manage symptoms of dumping syndrome, which can occur after gastric surgery and lead to chronic diarrhea. This approach helps slow gastric emptying and reduce symptoms.
