Gastrointestinal Tract Questions and Answers PDF Questions
Question 1 of 5
Which lymphatic areas are most commonly the site of inflammation?
Correct Answer: B
Rationale: The correct answer is B: palatine tonsils. Palatine tonsils are the most commonly inflamed lymphatic areas due to their location at the back of the throat where they can easily come into contact with pathogens. They play a crucial role in immune defense against infections. Peyer's patches are found in the small intestine and are involved in immune responses to pathogens in the digestive tract. Lingual tonsils are located at the base of the tongue and are less frequently inflamed compared to the palatine tonsils. Adenoids are located in the upper part of the throat behind the nose and are also less commonly inflamed than the palatine tonsils.
Question 2 of 5
The shortest section of the intestines is the _____.
Correct Answer: B
Rationale: The correct answer is B: duodenum. The duodenum is the shortest section of the small intestine, measuring around 25-30 cm in length. It is the first part of the small intestine and plays a crucial role in the digestion process by receiving partially digested food from the stomach and mixing it with digestive enzymes from the pancreas and bile from the liver. The colon (choice A) is the longest part of the large intestine, the ileum (choice C) and jejunum (choice D) are longer sections of the small intestine, following the duodenum in the digestive tract. Therefore, the duodenum is the correct answer as it is specifically the shortest part of the intestines.
Question 3 of 5
Which type of cells produce insulin in the pancreas?
Correct Answer: D
Rationale: The correct answer is D: beta cells. Beta cells are the specific type of cells in the pancreas responsible for producing insulin. They are located in the islets of Langerhans and play a crucial role in regulating blood sugar levels. Acinar cells (A) are responsible for producing digestive enzymes, duct cells (B) are involved in transporting pancreatic enzymes, and alpha cells (C) produce glucagon, which has the opposite effect of insulin in regulating blood sugar. Therefore, the correct choice is beta cells as they are the primary insulin-producing cells in the pancreas.
Question 4 of 5
A nurse is teaching a client how to do fecal occult blood testing. Which of the following statements by the client indicates a need for further teaching?
Correct Answer: A
Rationale: Rationale: A: Low-dose aspirin can cause false positive results in fecal occult blood testing due to its effect on gastrointestinal bleeding. Therefore, the client should inform the healthcare provider and consider stopping or adjusting the aspirin therapy during the testing period. B: Refraining from raw fruits and vegetables is correct as they can interfere with the test results. C: Avoiding red meats is correct as they can also affect the test results. D: Continuing Coumadin as prescribed is correct as it does not interfere with fecal occult blood testing.
Question 5 of 5
A nurse is planning care for a client who has diverticulitis. Which of the following menu selections should the nurse include in the plan?
Correct Answer: D
Rationale: The correct answer is D because grilled chicken breast with white rice is a low-fiber, easily digestible option suitable for a client with diverticulitis. High-fiber foods like celery (choice A), green salad (choice B), and green peas (choice C) can worsen symptoms by irritating the inflamed diverticula. Pork tenderloin (choice C) is high in fat, which can be difficult to digest. Grilled chicken breast with white rice provides protein and carbohydrates without aggravating the condition.
