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
Explanation
A. Before breakfast or lunch
Methylphenidate (Ritalin), a stimulant medication commonly used to treat attention deficit hyperactivity disorder (ADHD), is usually administered before breakfast or lunch for maximum effectiveness. This schedule helps align the peak concentration of the medication with the times when increased focus and attention are often needed, such as during school hours.
B. With meals
While it can be administered with meals, the goal is often to have the medication take effect before meals to help with focus and attention during activities like school or work.
C. After dinner
Administering methylphenidate after dinner may interfere with the patient's ability to fall asleep, as the medication can cause insomnia. It is generally recommended to avoid administering it in the late afternoon or evening.
D. At bedtime
Administering methylphenidate at bedtime is not appropriate due to the potential for insomnia. The stimulant effect of the medication is not aligned with the patient's sleep-wake cycle.
Correct Answer is C
Explanation
A. "I need to increase my fluid intake." - This is a correct statement. Sucralfate should be taken with plenty of water to ensure proper absorption and effectiveness.
B. "I need to report pain or vomiting of blood." - This is also a correct statement. Severe abdominal pain or vomiting of blood may indicate a serious issue and should be reported to the healthcare provider.
C. "I need to take Carafate 30 minutes after meals." - This is an incorrect statement. Sucralfate is typically taken on an empty stomach, about 1 hour before meals and at bedtime.
D. "I need to take Maalox 30 minutes before or after Carafate." - This statement is correct. Antacids like Maalox can interfere with the absorption of sucralfate. It's generally recommended to space them apart, taking sucralfate at least 30 minutes before or after antacids.
