A nurse is preparing to administer amoxicillin 500 mg PO. Available is amoxicillin 250 mg tablets.
How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
The correct answer is 2 tablets. Step 1 is to divide the prescribed dose by the available dose. So, 500 mg ÷ 250 mg = 2. Rationale: The nurse needs to administer the amount of medication that will equal the prescribed dose. Since each tablet contains 250 mg of amoxicillin, two tablets will provide the 500 mg dose.
So, the correct answer is 2 tablets.

Correct Answer is A
Explanation
Choice A rationale:
A decrease in blood pressure is a common side effect when a medication increases urine output, as the reduction in fluid volume can lead to lower blood pressure.
Choice B rationale:
While a decrease in blood pressure might be desired in certain conditions (like hypertension), in this context it is a side effect, not the primary desired effect.
Choice C rationale:
The therapeutic effect of the medication in this case is to increase urine output, not to decrease blood pressure.
Correct Answer is D
Explanation
Choice A rationale:
An allergic reaction refers to an immune response to a foreign substance. It does not describe the interaction between an antacid and ketoconazole.
Choice B rationale:
Displacement refers to one drug replacing another at the drug-binding site on proteins, altering the distribution of the displaced drug. It does not describe the interaction between an antacid and ketoconazole.
Choice C rationale:
Accumulation refers to the buildup of a drug in the body due to inadequate metabolism or excretion. It does not describe the interaction between an antacid and ketoconazole.
Choice D rationale:
A drug interaction occurs when the effect of one drug is altered by the administration of another drug. Antacids can slow the dissolution and absorption of ketoconazole, which is a type of drug interaction.
