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","B","E"]
Explanation
A. Avoiding hot, spicy foods
Spicy foods can increase the production of stomach acid and may irritate the esophagus, worsening GERD symptoms. Avoiding hot and spicy foods is a dietary measure to minimize the risk of symptom exacerbation.
B. Avoiding tobacco products
Tobacco use is a known risk factor for GERD. Smoking can relax the lower esophageal sphincter (LES), allowing stomach acid to flow back into the esophagus. Advising the patient to quit or avoid tobacco products can contribute to symptom management.
C. Drinking a glass of red wine with dinner
While red wine may have some potential benefits, alcohol, in general, can relax the LES, leading to increased reflux. Therefore, drinking red wine with dinner may not be recommended for someone experiencing GERD symptoms.
D. Eating a snack before bedtime
Eating close to bedtime can increase the likelihood of GERD symptoms, as lying down may allow stomach acid to flow back into the esophagus. The nurse may advise against eating a snack right before bedtime to minimize nighttime reflux.
E. Using a small pillow for sleeping
Elevating the head and upper body during sleep can help prevent stomach acid from flowing into the esophagus. Using a small pillow for sleeping is a measure to reduce nighttime reflux and alleviate GERD symptoms.
Correct Answer is A
Explanation
A. "Bisacodyl (Dulcolax) increases peristalsis to produce a bowel movement." - This is correct. Bisacodyl is a stimulant laxative that works by irritating the intestines, leading to increased peristalsis and bowel movements.
B. "Bisacodyl (Dulcolax) is incompatible with alcohol consumption." - There is no specific information suggesting incompatibility with alcohol. However, excessive alcohol consumption can contribute to constipation, and it's generally advisable to stay hydrated, which can be affected by alcohol intake.
C. "Bisacodyl (Dulcolax) should be avoided during pregnancy as it is teratogenic." - There is no strong evidence to suggest that bisacodyl is teratogenic. However, it is recommended to use laxatives cautiously during pregnancy and under the guidance of a healthcare provider.
D. "Bisacodyl (Dulcolax) may lead to paralytic ileus." - Paralytic ileus is not a common side effect of bisacodyl. However, it's important to use laxatives cautiously in individuals with a history of bowel obstruction or other gastrointestinal issues.
