أبكيك من حزني ويخنقني الأسى، وتقهرني الفجيعة، وأدمعي حجارة تسد مجدى أدمعي، رحلت إلى الله وتواريت عنا إلى غياهب الثرى، ومعارج القدر روحك من أجسادنا نحن، فصرنا بأنصاف أرواح، وأشلاء جسد. الثرياء، انتزع ما عرفناك إلا شهماً كريماً نقي الجوهر صادق القول، تجبر الخواطر وتقيل العثرات، ولا تتردد في مساعدة من عرفت ومن لم تعرف، فتربعت في حنايا القلوب. رحلت یا عبداللطيف وارتقيت نحو السماء تشيعك الدموع والقلوب، تاركاً خلفك بصمة خالدة في قلوب كل من عرفك، فكنت نعم الاخ و الزميل والصديق والإنسان.

a brief explanation of my answers to the 20 multiple choice questions Vascular obstruction is not a type of intestinal obstruction. Intestinal obstruction is caused by a mechanical blockage of the intestine, while vascular obstruction is caused by a blockage of a blood vessel. 2. A Adhesions are the most common cause of mechanical small bowel obstruction in adults. Adhesions are bands of scar tissue that can form after abdominal surgery. 3. D Paralytic ileus, pseudoobstruction, and neurogenic bowel dysfunction can all cause functional small bowel obstruction. Paralytic ileus is a temporary paralysis of the intestine that can occur after abdominal surgery, infection, or inflammation. Pseudoobstruction is a condition in which the intestine appears to be obstructed, but there is no mechanical blockage. Neurogenic bowel dysfunction is a condition in which the nerves that control the intestine are damaged. 4. A Colorectal cancer is the most common cause of mechanical large bowel obstruction in adults. 5. A The classic clinical signs and symptoms of intestinal obstruction are abdominal pain, distention, nausea, vomiting, and constipation. 6. A Abdominal X-ray and CT scan are the diagnostic tests of choice for intestinal obstruction. Abdominal X-ray can show signs of obstruction, such as dilated loops of bowel and gas-fluid levels. CT scan can provide more detailed images of the intestine and can help to identify the cause of the obstruction. 7. D Nasogastric tube decompression, intravenous fluids and electrolytes, and antibiotics are all used in the non-operative management of intestinal obstruction. Nasogastric tube decompression can help to relieve abdominal distention and vomiting. Intravenous fluids and electrolytes can help to prevent dehydration and electrolyte abnormalities. Antibiotics are used to prevent and treat infection. 8. D Failure of non-operative management, strangulation of the bowel, and full-thickness perforation of the bowel are all surgical indications for intestinal obstruction. 9. D Sepsis, ischemia, and perforation are all complications of intestinal obstruction. Sepsis is a life-threatening condition that occurs when infection spreads to the bloodstream. Ischemia is a condition in which the bowel does not receive enough blood. Perforation is a hole in the bowel wall. 10. B The mortality rate for intestinal obstruction is 10-20%. The mortality rate is higher in patients who are elderly or have underlying medical conditions. 11. D Pregnancy is not a risk factor for intestinal obstruction. 12. D Avoiding surgery, avoiding hernias, and treating inflammatory bowel disease can all help to prevent intestinal obstruction. 13. D A high white blood cell count is a sign of infection, but it is not a sign of strangulation of the bowel. 14. A Nasogastric tube decompression is a non-surgical option for intestinal obstruction. Resection of the affected bowel segment, creation of a colostomy or ileostomy are all surgical options for intestinal obstruction. 15. B The prognosis for patients with intestinal obstruction is good with early diagnosis and treatment. The prognosis is worse in patients who are elderly or have underlying medical conditions. 16. D Advanced age is not a risk factor for Richter's hernia. 17. D Strangulation of the bowel, ischemia of the bowel, and perforation of the bowel are all complications of Richter's hernia. 18. A Emergency surgery is the treatment for Richter's hernia. The goal of surgery is to remove the strangulated bowel and repair the hernia. 19. D Black stools are a sign of bleeding from the bowel. They are not a sign of gangrene of the bowel. 20. A Emergency surgery is the treatment for gangrene of the bowel. The goal of surgery is to remove the gangrenous bowel and repair the intestine.
