Which statement indicates a correct understanding of topical drug absorption in a pediatric patient?.
Because the skin is not fully hydrated at this age, water-soluble drugs are not readily absorbed.
Inflammation decreases the amount of drug absorbed.
Topical administration with percutaneous absorption is usually effective in infants.
Infants wearing plastic-coated diapers are more susceptible to skin absorption.
The Correct Answer is D
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.

Correct Answer is C
Explanation
Choice A rationale:
Trough levels are the lowest concentration in the patient’s bloodstream, hence they are not the best indicator of the amount of circulating medication.
Choice B rationale:
The term ‘Drug’ is too general and does not specifically refer to the amount of medication in the patient’s bloodstream.
Choice C rationale:
Peak levels are the highest concentration of a drug in the patient’s bloodstream after administration. This is when the amount of the medication in the body is likely to be highest.
Choice D rationale:
Therapeutic levels refer to the range in which a drug is expected to be effective without causing any serious problems to the patient. It does not directly indicate the amount of circulating medication.
Correct Answer is C
Explanation
Choice A rationale:
Giving the medication as ordered despite the patient’s stated allergy could lead to a severe allergic reaction.
Choice B rationale:
While checking the drug insert for information on reactions to the drug is important, the immediate action should be to withhold the medication.
Choice C rationale:
Withholding the medication and notifying the prescriber of the situation is the safest course of action when a patient states they are allergic to the medication.
Choice D rationale:
Giving the medication and monitoring the patient for adverse effects is not safe if the patient has stated they are allergic to the medication.
