A patient takes two medications.
Drug A is taken once per day; drug B is taken every 8 hours.
Which conclusion about drug A is correct?
Has a wider therapeutic range than drug B.
Has a higher rate of protein binding than drug B.
Has a longer half-life than drug B.
Is less toxic than drug B.
The Correct Answer is C
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.

Correct Answer is C
Explanation
Choice A rationale:
Decreased splanchnic blood flow can affect drug absorption and metabolism, but it does not directly increase the risk of gastric irritation from NSAIDs.
Choice B rationale:
Prolonged secretion of gastric acid can contribute to conditions like gastroesophageal reflux disease (GERD), but it is not the primary factor increasing the risk of gastric irritation from NSAIDs in older adults.
Choice C rationale:
Delayed gastric emptying is the correct answer. It allows drugs to stay in contact with the stomach lining for a longer time, which can increase the risk of gastric irritation from NSAIDs.
Choice D rationale:
Loss of cells from the gastric plexus can affect gastric function, but it is not directly linked to an increased risk of gastric irritation from NSAIDs.
Correct Answer is D
Explanation
Choice A rationale:
The term “Aged” is not a specific life stage and can refer to anyone who is old, without specifying an age range.
Choice B rationale:
“Elderly” is often used to refer to individuals who are in their 80s or 90s, which is older than 653.
Choice C rationale:
“Adult” typically refers to individuals in the age range of 18 to 64 years, so a 65-year-old would not fall into this category.
Choice D rationale:
“Older adult” is a term often used to refer to individuals who are 65 years and older. So, the correct answer is Choice D, Older adult.
