Question 1 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.

D: Continuing Coumadin as prescribed is correct as it does not interfere with fecal occult blood testing.
Question 3 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.
Question 4 of 5
Peritonitis can occur as a complication of:
Correct Answer: A
Rationale: Peritonitis can occur as a complication of septicemia because the infection can spread to the peritoneum, causing inflammation and infection. Septicemia is the presence of pathogenic organisms in the bloodstream, which can lead to systemic inflammation and infection throughout the body, including the peritoneum. In contrast, multiple organ failure, hypovolemic shock, and peptic ulcer disease are not direct causes of peritonitis. Multiple organ failure involves dysfunction of various organs, hypovolemic shock is caused by severe blood loss leading to inadequate perfusion, and peptic ulcer disease is related to the erosion of the stomach lining. Hence, the correct answer is A, as septicemia is a direct cause of peritonitis.
Question 5 of 5
The outer layer of the GI tract is composed of connective tissue and a simple squamous epithelium. This tunic is called the tunica ______ and the simple squamous epithelium is called the ______.
Correct Answer: B
Rationale: The correct answer is B: serosa, visceral peritoneum. The outer layer of the GI tract is called the serosa, which is composed of connective tissue and a simple squamous epithelium known as the visceral peritoneum. The serosa helps to protect and support the GI tract. A: adventitia, visceral peritoneum - Adventitia is a dense connective tissue layer found in structures that are not intraperitoneal, whereas the visceral peritoneum is specific to the peritoneal cavity. C: serosa, parietal peritoneum - The parietal peritoneum is the outer layer of the peritoneum lining the abdominal cavity, not the outer layer of the GI tract. D: adventitia, parietal peritoneum - Similar to choice A, the parietal peritoneum is not part of the outer layer of the GI tract.
