4	Basal and peak acid output are most important in the diagnosis of:	A4
	A. Duodenal ulcer B. Gastrinoma C. Gastric ulcer D. Gastric carcinoma E. Rickets Classically basal and peak acid output after pentagastrin stimulation are the same in gastrinoma. These tests do not contribute to the diagnosis of the other conditions	False True False False False

	A. Motor neurone disease B. Marfan’s syndrome C. Friedreich’s ataxia D. Diabetes insipidus E. Diabetes mellitus Motility disorders in diabetes mellitus are common and often difficult to treat	False False False False True

7	The success of peptic ulcer surgery can be judged by:	A7
	A. Insulin test meal B. Sham feeding C. Pre- and post-operative pentagastrin test meals D. Symptoms E. Gastric pH monitoring All of these techniques have been used in assessment of peptic ulcer surgery, but are seldom required now	True True True True True
8	Helicobacter pylori bacteria:	A8
	A. Live in gastric acid B. Adhere to the gastric mucosa in an alkaline layer C. Are never seen in healthy people D. Can be simply identified in the endoscopy room by their urease activity E. Are associated with peptic ulcer relapse 50% of the world’s population carry Helicobacter pylori, which lives closely applied to the gastric epithelium under the mucus layer. It is a combination of gastric acid and Helicobacter pylori together with other factors which is responsible for peptic ulcer disease.

	A. Are slow to take effect B. Have some action on gastric acid C. Have an unusually high relapse rate D. Cause diarrhoea E.

	A. Weight / height B. Weight² / height C. Weight / height² D. Weight² / height² E. Weight³ / height Body mass index (BMI or Quelet’s Index) is calculated from weight in kilograms divided by the square of the height in metres. The ideal is 20-25. Over 30 is obese and over 40 is morbidly obese.	False False True False False
14	Fibre-optic upper digestive endoscopy:	A14
	A. Is less accurate than video endoscopy B. Is superior to barium meal examination C. Replaces the need for small bowel biopsy capsules in coeliac disease D. Has no mortality E. Usually requires IV sedation which may be reversed with flumazenil Video and fibre-optic gastroscopy yields equivalent results and are more reliable than barium meal examination overall. Procedures may be conducted without sedation and this is often safer. Complications and deaths often relate to cardio-respiratory problems in the elderly.	False True True False False
