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.

Explanation
A. "I will avoid foods high in fat." - This is a correct statement. High-fat foods can contribute to the symptoms of GERD.
B. "I will eat small frequent meals and have a snack at bedtime." - This is a correct statement. Eating smaller, more frequent meals and avoiding large meals before bedtime can help manage GERD symptoms.

D. "I will wait 2 hours after eating lunch before lying down for a nap." - This is a correct statement. Waiting a few hours after eating before lying down can help prevent stomach contents from refluxing into the esophagus.
Correct Answer is B
Explanation
A. The patient's understanding of the medication:
While it's important for the patient to understand their medication, assessing their understanding is typically done through patient education and counseling. This assessment is vital for promoting adherence and safe medication practices but is not the primary consideration immediately before administration.
B. The patient's ability to swallow:
This is the correct answer. Assessing the patient's ability to swallow is crucial before administering oral medications to ensure that the patient can safely and effectively take the prescribed medication without the risk of aspiration or choking.
C. The patient's allergies:
Assessing the patient's allergies is an essential step in medication administration, but it is generally part of the overall medication safety process. It may not be the primary assessment immediately before administering an oral medication, but it is a crucial consideration.
D. The eyesight:
The patient's eyesight is not typically a primary assessment before administering oral medications. While visual impairments can affect a patient's ability to read medication labels or instructions, it is not the immediate concern when assessing readiness for oral medication administration.
