Mr. D is a 60-yr. old with fever, abdominal pain, decreased appetite, and nausea for the
past 24 hrs. There are no new foods in his diet, and he has not been travelling or eating
out. He had a screening colonoscopy 5 years ago that showed diverticula in his colon,
but he never had any problem with them.
Physical: Mr. D appears tired and in pain. Exam is significant for abdominal tenderness
to touch.
Labs/Tests:
White blood count is elevated on CBC
Amylase, lipase and liver function tests are normal
Abdominal CT scan shows diverticulitis
Assessment/Plan:
Diverticulitis- this occurs when diverticula (thin areas in the wall of the intestine that form
"out pocketing") become inflamed. Risk factors include a low fiber diet and constipation.
Treatment for diverticulitis includes avoiding solid foods, hydration, and antibiotics.
Deliverables
Answer the following questions and save your responses in a Microsoft Word
document. Provide a scholarly resource in APA format to support your answers.
1. Provide a detailed description of the path of chyme, and later feces, from the
duodenum to the anus, identifying the different portions of the small and large
intestines.
The small intestine receives chyme from the stomach the chyme is mixed
with secretions from the liver and pancreas and released into the
duodenum. Segmentations mix the chyme with digestive juices and brings
the food into contact with the mucosa for absorption, peristalsis propels
chyme through small intestine into the jejunum. It has finger like structures
called villi that assist with the absorption of the end products of digestion
into the bloodstream, by this time chyme has reached the ileum and most
of the digestion processes involving carbohydrate, protein and fats have
occurred. It then releases hormones to generate the feeling of fullness.
Undigested food is passed through the small intestine known as caecum.
It is a small pouch that acts as a storage site.
Slower peristalsis movements push undigested food remains along the
colon; it then mixes freely with the resident bacterial population. The
bacteria ferment some of the food remains, producing short-chain fatty
acids as well other important chemicals such as vitamin K. The sigmoid
colon in the large intestine then take the liquid from the small intestine and
