1.
Which are histamine H2 antagonists?
Correct Answer(s)
A. Famotidine
B. Cimetidine
Explanation
Famotidine and Cimetidine are both histamine H2 antagonists. These medications work by blocking the action of histamine, a chemical in the body that is responsible for stimulating acid production in the stomach. By inhibiting the H2 receptors, these drugs reduce the amount of acid produced, making them effective in treating conditions such as gastric ulcers, gastroesophageal reflux disease (GERD), and heartburn. Pantoprazole and Sucralfate, on the other hand, are not histamine H2 antagonists. Pantoprazole is a proton pump inhibitor that reduces acid production by a different mechanism, while Sucralfate is a medication that forms a protective layer over ulcers, promoting healing.

6.
What is the action of famotidine, cimetidine?
Correct Answer
A. Decreased secretion of gastric acid.
Explanation
Famotidine and cimetidine are both H2 receptor antagonists, which means they block the action of histamine on the H2 receptors in the stomach. Histamine normally stimulates the secretion of gastric acid, so by blocking this action, famotidine and cimetidine decrease the secretion of gastric acid. This can help in the treatment of conditions like peptic ulcers and gastroesophageal reflux disease (GERD), as excessive gastric acid can contribute to the development of these conditions. Therefore, the correct answer is decreased secretion of gastric acid.
7.
What is the action of pantoprazole, omeprazole?
Correct Answer
A. Healing of duodenal ulcers.
Explanation
Pantoprazole and omeprazole are proton pump inhibitors (PPIs) that work by reducing the production of stomach acid. This decrease in acid production allows the duodenal ulcers to heal by reducing the irritation and inflammation caused by excess acid. Therefore, the action of pantoprazole and omeprazole is the healing of duodenal ulcers.
8.
What is the action of laxatives?
Correct Answer
C. Softening and passage of stool.
Explanation
Laxatives are substances that help soften and facilitate the passage of stool. They work by increasing the frequency and ease of bowel movements, making it easier for stool to pass through the intestines. Laxatives are commonly used to relieve constipation and promote regular bowel movements. They are not specifically indicated for relief from diarrhea, reduction of symptoms of ulcerative colitis, or prevention of gastric ulceration from NSAIDs.
9.
Which are side effects of Histamine H2 Antagonists?
Correct Answer(s)
A. Confusion
C. Arrhythmias
E. Agranulocytosis
G. Aplastic Anemia
Explanation
Histamine H2 antagonists are a class of medications commonly used to reduce stomach acid production. They are mainly used to treat conditions such as gastric ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. The side effects mentioned in the answer are potential side effects of histamine H2 antagonists. Confusion can occur as a result of the medication's effect on the central nervous system. Arrhythmias (abnormal heart rhythms) can be a rare side effect. Agranulocytosis, a condition characterized by a severe decrease in white blood cells, and aplastic anemia, a condition where the body stops producing enough new blood cells, are also potential side effects of these medications.
10.
What is the action of Misoprostol?
Correct Answer
C. Prevention of gastric ulceration from NSAIDs
Explanation
Misoprostol is a medication that is commonly used to prevent gastric ulceration caused by non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs can cause damage to the lining of the stomach, leading to the formation of ulcers. Misoprostol works by reducing the production of gastric acid and increasing the production of protective mucus in the stomach, thereby preventing the formation of ulcers. It is not used for inhibiting gastric acid secretion, relieving heartburn, or softening and passage of stool.
11.
What is the action of Metocloperamide?
Correct Answer
A. Stimulates motility upper GI tract and accelerates gastric emptying.
Explanation
Metocloperamide is a medication that stimulates the motility of the upper gastrointestinal (GI) tract and accelerates gastric emptying. This means that it helps to improve the movement of food through the digestive system and speeds up the process of emptying the stomach. This action can be beneficial in conditions such as gastroparesis, where the stomach takes longer than normal to empty its contents. By enhancing GI motility and gastric emptying, metocloperamide can help relieve symptoms such as nausea, vomiting, and bloating.
12.
What is the action of Loperamide?
Correct Answer
A. Relief from diarrhea
Explanation
Loperamide is a medication that is primarily used to relieve symptoms of diarrhea. It works by slowing down the movement of the intestines, allowing for more water to be absorbed and resulting in firmer stools. This action helps to reduce the frequency and urgency of bowel movements, providing relief from diarrhea.
13.
What is the action of sulfasalazine and infliximab?
Correct Answer
B. Reduction in symptoms of ulcerative colitis
Explanation
Sulfasalazine and infliximab are medications that are used to reduce the symptoms of ulcerative colitis. Ulcerative colitis is a chronic inflammatory bowel disease that causes inflammation and ulcers in the colon and rectum. These medications work by suppressing the immune system and reducing inflammation in the intestines, which helps to alleviate symptoms such as abdominal pain, diarrhea, and rectal bleeding. They are not used for healing duodenal ulcers, relieving heartburn, or softening and passing stool.
14.
What is the action of Budesonide?
Correct Answer
A. Improvement of Crohn's symptoms.
Explanation
Budesonide is a corticosteroid medication that is commonly used to treat Crohn's disease, an inflammatory bowel disease. It works by reducing inflammation in the intestines, which can help improve symptoms such as abdominal pain, diarrhea, and weight loss. Therefore, the action of Budesonide is the improvement of Crohn's symptoms.
15.
What is the action of antiemetics?
Correct Answer
A. Prevention and decrease of nausea and vomiting
Explanation
Antiemetics are medications that are used to prevent and decrease nausea and vomiting. These drugs work by blocking certain receptors in the brain that trigger the vomiting reflex. They can be used to treat a variety of conditions that cause nausea and vomiting, such as motion sickness, chemotherapy-induced nausea, and post-operative nausea. By preventing and reducing these symptoms, antiemetics can help improve the overall well-being and comfort of patients.
16.
What is the action of stool softeners?

C. Softening and passage of stool.
Explanation
Stool softeners are medications that help in softening the stool and promoting its passage. They work by increasing the amount of water in the stool, making it easier to pass. Stool softeners are commonly used to relieve constipation and prevent straining during bowel movements. By softening the stool, they help to prevent discomfort and promote regular bowel movements. Therefore, the action of stool softeners is to soften and facilitate the passage of stool.
17.
Which is the action of Dicyclomine?
Correct Answer
B. Decreased GI motility.
Explanation
Dicyclomine is a medication that works by decreasing GI motility. This means that it slows down the movement of the gastrointestinal tract, including the stomach and intestines. By reducing GI motility, dicyclomine can help to relieve symptoms such as abdominal pain, cramps, and diarrhea. This action is particularly useful in conditions such as irritable bowel syndrome (IBS) where increased GI motility can contribute to these symptoms. Therefore, the correct answer is "Decreased GI motility."
18.
What is the action of Octreotide?
Correct Answer
B. Increases absorption of F&E from the GI tract and increases transit time.
Explanation
Octreotide is a medication that is commonly used to treat conditions such as acromegaly, carcinoid syndrome, and certain types of tumors. It works by inhibiting the release of various hormones in the body, including growth hormone and insulin. This action helps to increase the absorption of fluids and electrolytes from the gastrointestinal tract and also slows down the transit time of food through the digestive system. As a result, it can help to alleviate symptoms such as diarrhea and excessive fluid loss.
