A patient with a gastric ulcer is ordered sucralfate (Carafate). How does this medication works?
calm the patient to reduce acid production
block the H2 receptors
neutralize the gastric acids
coat the gastric lining
The Correct Answer is D
A. Calm the patient to reduce acid production.
This description is not accurate for sucralfate. Calming the patient to reduce acid production is typically associated with medications like proton pump inhibitors (PPIs) or H2 receptor blockers.
B. Block the H2 receptors.
Blocking H2 receptors is the mechanism of action for H2 receptor blockers, such as ranitidine. It is not the mechanism of action for sucralfate.
C. Neutralize the gastric acids.
Neutralizing gastric acids is the mechanism of action for antacids, such as aluminum hydroxide or calcium carbonate. Sucralfate works differently; it forms a protective coating on the gastric lining rather than directly neutralizing acids.
D. Coat the gastric lining.
This is the correct mechanism of action for sucralfate. It forms a protective coating on the gastric lining, adhering to the ulcer site and providing a barrier against gastric acid.

Correct Answer is ["A","D"]
Explanation
A. Blood dyscrasias: This is a correct choice. Phenytoin can cause blood dyscrasias, including conditions like leukopenia, thrombocytopenia, and anemia.
B. Hyperglycemia: This is not typically associated with phenytoin. The primary adverse effects related to blood sugar are usually changes in glucose metabolism or hypoglycemia.
C. Urinary retention: This is not a common adverse effect of phenytoin. It is more associated with other medications or medical conditions.
D. Gingival hyperplasia: This is a correct choice. Phenytoin is known to cause gingival hyperplasia, which is an overgrowth of the gum tissue.
E. Sedation: This is not a common adverse effect of phenytoin. Phenytoin is more known for causing CNS-related side effects like nystagmus, ataxia, and dizziness.
Correct Answer is B
Explanation
A. Decreased ascites
Ascites (accumulation of fluid in the abdominal cavity) is more directly related to portal hypertension and liver cirrhosis. While lactulose may contribute to fluid balance, its primary therapeutic effect in hepatic encephalopathy is the reduction of ammonia levels.
B. Decreased ammonia level
Lactulose is a medication commonly used in the treatment of hepatic encephalopathy, a condition associated with liver disease. The therapeutic effect of lactulose in this context is to reduce blood ammonia levels. Lactulose works by promoting the excretion of ammonia in the form of ammonium ions in the colon, thereby lowering ammonia concentrations in the blood.
C. Decreased jaundice
Jaundice is often associated with liver dysfunction, but lactulose is not primarily used to address jaundice. Its primary role in liver disease is in the management of hepatic encephalopathy.
D. Decreased blood pressure
Blood pressure is not a direct therapeutic target of lactulose in the context of liver disease. Lactulose's primary therapeutic effect is related to reducing ammonia levels and managing hepatic encephalopathy.
