A nurse is preparing to administer amoxicillin 350 mg PO. Available is amoxicillin 250 mg/5 mL. How many mL should the nurse administer?
(Round to the nearest whole number.)
The Correct Answer is ["7"]
The correct answer is 7 mL. Step 1 is to calculate the concentration of amoxicillin in mg/mL: 250 mg ÷ 5 mL = 50 mg/mL.
Step 2 is to use the calculated concentration to find the volume: Volume (mL) = 350 mg ÷ 50 mg/mL = 7 mL.

Correct Answer is ["2"]
Explanation
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 C
Explanation
Choice A rationale:
The frequency of drug administration doesn’t necessarily determine the therapeutic range.
Choice B rationale:
Protein binding is not directly related to the frequency of drug administration.
Choice C rationale:
Drug A has a longer half-life than drug B. This is because drugs with longer half-lives need to be administered less frequently.
Choice D rationale:
The toxicity of a drug is not determined by the frequency of its administration.
