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 ["C","D"]
Explanation
A. Administer morphine 1-2 mg IV
Administering morphine is not a preventive measure for spinal headaches. It may be considered for pain relief if the patient experiences discomfort after the effects of spinal anesthesia wear off.
B. Ambulate the client as soon as she gets feelings back
Ambulating the patient too soon after spinal anesthesia is generally not recommended. Staying in bed initially helps prevent complications like spinal headaches.
C. Increase fluid intake
Adequate hydration is important after spinal anesthesia to help maintain cerebrospinal fluid volume. Increasing fluid intake can reduce the risk of developing a spinal headache.
D. Encourage the patient to stay flat in bed
Remaining in a flat or slightly elevated position helps minimize cerebrospinal fluid leakage from the puncture site, reducing the likelihood of developing a spinal headache. This position is typically recommended for a specific duration after spinal anesthesia.
E. Position the client in high Fowler's position
Placing the patient in high Fowler's position (sitting upright) may increase the risk of cerebrospinal fluid leakage, potentially leading to a spinal headache. This position is not recommended for preventing spinal headaches after spinal anesthesia.
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.
