Explanation
To calculate the dose of fluconazole for a child who weighs 44 pounds, you need to convert the weight to kilograms and the dose to milligrams.
One kilogram is equal to 2.2 pounds, so 44 pounds is 44 / 2.2 = 20 kilograms.
The dose of fluconazole is 5 mg/kg, so 5 mg x 20 kg = 100 mg.
The label on the bottle says that each tablet contains 50 mg of fluconazole, so you need to divide the dose by the tablet strength to get the number of tablets. 100 mg / 50 mg = 2 tablets.
Therefore, you should administer two tablets of fluconazole once a day for this child.
Correct Answer is D
Explanation
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.
