Question 1

Irritable bowel syndrome (IBS) is defined as:&#10;A) Low blood pressure&#10;B) Dysfunction of intestinal&#10;C) Dysfunction of intestinal motility&#10;D) High blood pressure

Accepted Answer

Irritable bowel syndrome (IBS) is defined as a dysfunction of intestinal motility and a commonly diagnosed condition. IBS can also cause intestinal pain, discomfort, diarrhea, and/or constipation.

Question 2

What other conditions are excluded with the diagnosis of irritable bowel syndrome (IBS)? Select all that apply.&#10;A) Celiac disease&#10;B) Gluten intolerance&#10;C) Food allergies&#10;D) High blood pressure

Accepted Answer

Irritable bowel syndrome (IBS) is diagnosed by excluding celiac disease, gluten intolerance, and other food allergies. Celiac disease is an immune reaction to gluten. Gluten intolerance is a sensitivity to gluten and causes a reaction.

Question 3

Which disease is defined as patches of inflamed intestinal walls?&#10;A) Celiac disease&#10;B) Irritable bowel syndrome&#10;C) Hypertension&#10;D) Crohn's disease

Accepted Answer

Crohn's disease is defined as inflamed patches of intestinal walls that sit next to healthy intestinal walls. These damaged patches can be found in the small intestine or anywhere in the GI tract.

Question 4

Which disease presents as a continuous inflammation that starts in the rectum and spreads to the colon?&#10;A) Celiac disease&#10;B) Crohn's disease&#10;C) Irritable bowel syndrome&#10;D) Ulcerative colitis

Accepted Answer

Ulcerative colitis (UC) is defined as a continuous inflammation that starts in the rectum and spreads to the colon. UC is a type of irritable bowel disease that causes inflammation or ulcers.

Question 5

The walls of the GI tract consist of how many layers?&#10;A) 2&#10;B) 5&#10;C) 3&#10;D) 4

Accepted Answer

The walls of the GI tract consist of 5 layers: the inner layer, the submucosal or middle layer, the submucosal connective tissue (lamina propria), muscle layers (longitudinal and circular), and peritoneum (outer layer).

Question 6

Which layer of the GI tract lubricates and protects the intestines by producing mucus?&#10;A) Muscle layer&#10;B) Middle layer&#10;C) Inner layer&#10;D) Outer layer

Accepted Answer

The walls of the GI tract consist of 5 layers: the inner layer, the submucosal or middle layer, the submucosal connective tissue (lamina propria), muscle layers (longitudinal and circular), and peritoneum (outer layer). The inner layer of the GI tract lubricates and protects the intestines by producing mucus or goblet cells.

Question 7

Which layer of the GI tract covers the entire intestine?&#10;A) Muscle layer&#10;B) Middle layer&#10;C) Inner layer&#10;D) Outer layer

Accepted Answer

The walls of the GI tract consist of 5 layers: the inner layer, the submucosal or middle layer, the submucosal connective tissue (lamina propria), muscle layers (longitudinal and circular), and peritoneum (outer layer). The outer layer or the peritoneum of the GI tract functions to attach and cover the entire intestine.

Question 8

Which layer of the GI tract produces immunoglobulins by its plasma cells and lymphocytes?&#10;A) Lamina propia&#10;B) Submucosal&#10;C) Circular&#10;D) Peritoneum

Accepted Answer

The walls of the GI tract consist of 5 layers: the inner layer, the submucosal or middle layer, the submucosal connective tissue (lamina propria), muscle layers (longitudinal and circular), and peritoneum (outer layer). The submucosal connective tissue or lamina propria layer is responsible for producing immunoglobulins that are synthesized by plasma cells and lymphocytes.

Question 9

What is the initial phase of gastric secretion called?&#10;A) Lamina propria&#10;B) Intestinal&#10;C) Cephalic&#10;D) Gastric

Accepted Answer

The initial phase of gastric secretion is called the cephalic phase. In the cephalic phase, the vagal nerve responds to mental and sensory stimulation and starts gastric secretion.

Question 10

In the ____ phase of gastric secretion, the duodenum responds to the production of chyme by stimulating the release of gastrin in the intestines.&#10;A) Lamina propria&#10;B) Intestinal&#10;C) Cephalic&#10;D) Gastric

Accepted Answer

In the final phase of the intestinal phase of gastric secretion, the duodenum responds to the production of chyme, which is partially digested food, and enzymes mixed together and stimulates gastrin's release into the intestines. When gastric acid enters the small intestine, the duodenum initiates the inhibition of gastric secretion.

Question 11

What is GI motility stimulated by?&#10;A) Hypothalamus&#10;B) Sympathetic nerves&#10;C) Chyme&#10;D) Parasympathetic nerves

Accepted Answer

The answer of What is GI motility stimulated by?&#10;A) Hypothalamus&#10;B)...

Question 12

What percentage of water is absorbed in the small intestine?&#10;A) 70%-80%&#10;B) 85%-95%&#10;C) 85%-90%&#10;D) 80%-90%

Accepted Answer

The answer of What percentage of water is absorbed in...

Question 13

Where is the largest proportion of bacteria found?&#10;A) Stomach&#10;B) Small intestine&#10;C) Large intestine&#10;D) Pancreas

Accepted Answer

The answer of Where is the largest proportion of bacteria...

Question 14

What is an emergency complication of inflammatory bowel disease (IBD)?&#10;A) Stomachache&#10;B) Diarrhea&#10;C) Fever&#10;D) Toxic megacolon

Question 15

Which is not a risk factor of IBD?&#10;A) Gender&#10;B) Ethnicity&#10;C) Family history&#10;D) Education level
