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.)

Choice A rationale:
The blood flow of the mucous lining of the stomach and intestines can affect how quickly a drug is absorbed.
Choice B rationale:
Drug distribution refers to how a drug spreads throughout the body, not its absorption in the gastrointestinal tract.
Choice C rationale:
Enzyme activity can affect how a drug is metabolized and absorbed.
Choice D rationale:
Gastric pH can affect drug absorption as some drugs are better absorbed in an acidic environment, while others are better absorbed in an alkaline environment.
Choice E rationale:
Gastric emptying time can affect drug absorption. Drugs may stay in contact with the absorptive tissue longer if the gastric emptying time is slower, allowing for increased absorption.

Choice A rationale:
Medical diagnoses do not tend to vary depending on the patient’s rate of recovery. They are based on the disease or condition.
Choice B rationale:
Nursing diagnoses do refer to the patient’s ability to function in activities of daily living. They focus on the patient’s response to their health condition.
Choice C rationale:
Nursing diagnoses do not focus on alterations in the patient’s function and structures. This is more related to medical diagnoses.
Choice D rationale:
Nursing diagnoses do not result in diagnoses of disease that impairs normal physiologic function. This is the role of medical diagnoses.
