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 D
Explanation
Choice A rationale:
Protein binding does not inactivate the drug. Instead, it can affect the drug’s distribution and bioavailability.
Choice B rationale:
Protein binding does not directly increase the risk of an allergic reaction. Allergic reactions are typically immune responses to a drug, not a result of protein binding.
Choice C rationale:
An idiosyncratic reaction is an unusual or unexpected reaction to a drug, which is not related to protein binding.
Choice D rationale:
Protein binding can lead to the accumulation of the drug. Drugs often cannot cross membranes mainly due to the high molecular mass of the drug-protein complex, resulting in the accumulation of the active compounds.
