More common in developed countries where processed foods and low-fiber diets are typical. - Correct answer-Diverticular Disease Asymptomatic diverticular disease, usually with multiple diverticula present - Correct answer-Diverticulosis Diverticula have become inflamed, usually because of retained fecal matter. Can result in potentially fatal obstructions, infection, abscess, perforation, peritonitis, hemorrhage, and shock. Often asymptomatic until the condition becomes serious - Correct answerDiverticulitis Manifestations?: abdominal cramping followed by passing a large quantity of frank blood, low-grade fever, abdominal tenderness (usually left lower quadrant), abdominal distension, constipation, obstipation, nausea, vomiting, palpable abdominal mass, and leukocytosis - Correct answer-Diverticular Disease Consist of physical barriers, whereas functional obstructions result from GI tract dysfunction. Partial or complete blockage of small or large bowel. - Correct answerMechanical Bowel Obstruction Caused by?: foreign bodies, adhesions, hernia, tumors, impacted feces, volvulus, intussusception, strictures, Crohn's Disease, diverticulitis, Hirschsprung's disease, and fecal impaction. - Correct answer-Mechanical Bowel Obstruction Also called paralytic ileuses, usually result from neurologic impairment; intra-abdominal surgery complications; chemical, electrolyte, and mineral disturbances; intra-abdominal infections; abdominal blood supply impairment; renal and lung disease; and use of certain medications - Correct answer-Functional Obstructions Most commonly occurs as a secondary tumor that he metastasized from the breast, lung, or other GI structures - Correct answer-Liver Cancer Causes of primary tumors in ____: chronic cirrhosis and hepatitis - Correct answer-Liver Cancer Manifestations of?: Similar to those of other liver diseases.
