ATI Gastrointestinal System Quizlet

Correct Answer: C

Rationale: Medical management of diverticulitis typically includes the administration of antibiotics to treat infection and inflammation.

Correct Answer: B

Rationale: The correct answer is B: 'A noninflamed outpouching of the intestine.' Diverticulosis refers to the presence of small, bulging pouches (diverticula) that can form in the lining of the digestive system, especially the colon. These pouches are typically noninflamed. Choice A is incorrect because it describes diverticulitis, which is the inflammation of these pouches. Choice C is incorrect as it defines bowel obstruction, not diverticulosis. Choice D is incorrect as it refers to a hernia, not diverticulosis.

Correct Answer: C

Rationale: A gastroscopy is performed to visualize the stomach lining and obtain biopsies to diagnose gastric cancer.

Correct Answer: D

Rationale: The correct answer is D: Steady. The pain associated with appendicitis is typically constant and steady, especially in the lower right quadrant of the abdomen. It is not described as aching (choice A) because it is more persistent and severe than a dull ache. It is not fleeting (choice B) as appendicitis pain tends to worsen over time. It is also not intermittent (choice C) as the pain is continuous and does not come and go.

Correct Answer: C

Rationale: Radiation therapy is commonly used for rectal cancer to shrink the tumor before surgery, which is not typically done for colon cancer.
