Which statement indicates a correct understanding of topical drug absorption in a pediatric patient?.

Choice A rationale:
While it’s true that hydration affects skin absorption, it’s not accurate to say that water-soluble drugs are not readily absorbed because the skin is not fully hydrated.
Choice B rationale:
Inflammation can actually increase the amount of drug absorbed due to increased blood flow and permeability.
Choice C rationale:
Topical administration with percutaneous absorption can be effective in infants, but it’s not always the case.
Choice D rationale:
Infants wearing plastic-coated diapers are indeed more susceptible to skin absorption. This is because the occlusive nature of the diaper can enhance absorption by increasing the hydration of the skin.

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.
