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 ["2.5"]
Explanation
To calculate the amount of solution needed for each dose, we need to use the formula:
Amount of solution (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the given values, we get:
Amount of solution (mL) = 50 mg / 20 mg/mL
Simplifying, we get:
Amount of solution (mL) = 2.5 mL
Therefore, the nurse must administer 2.5 mL of the solution for each dose.
Correct Answer is ["B","C","D","E"]
Explanation
A. "This medication may make my movements smoother."
This statement is correct. Carbidopa-levodopa is used to improve motor symptoms in parkinsonism, making movements smoother.
B. "My skin may turn yellow if I miss too many doses."
This statement is not accurate. Yellowing of the skin (jaundice) is not a known side effect of carbidopa-levodopa. This statement indicates a need for further clarification.
C. "I need to take vitamin B6 supplements with this medication."
This statement is incorrect. While vitamin B6 (pyridoxine) can reduce the effectiveness of levodopa, carbidopa is included in the formulation to prevent its peripheral conversion, allowing more levodopa to reach the brain. Vitamin B6 supplements are generally not recommended with carbidopa-levodopa.
D. "I should take this medicine on an empty stomach."
This statement is not accurate. Carbidopa-levodopa is typically taken with food to reduce gastrointestinal side effects. Taking it on an empty stomach may increase the risk of nausea.
E. "I need to check my blood sugar regularly while taking this."
This statement is not directly related to carbidopa-levodopa. Monitoring blood sugar is essential for individuals with diabetes but is not a specific requirement related to this medication.
