Correct Answer is C

Explanation

Choice A rationale:
The term “Aged” generally refers to individuals who are in the late stages of life, often those over 652. This does not apply to a 40-year-old patient.
Choice B rationale:
“Elderly” is a term often used to refer to individuals who are 65 years of age or older. A 40-year-old patient does not fall into this category.
Choice C rationale:
A 40-year-old patient is considered an “Adult”. According to Erikson’s stages of development, the stage of “generativity vs. stagnation” begins at age 40 and lasts until age 653.
Choice D rationale:
“Older adult” typically refers to individuals who are in their late 60s and beyond. This does not apply to a 40-year-old patient.

A. Metabolism of drug by the kidneys is slower, so reduced dosage is needed. B. Absorption of oral medications is more predictable but more rapid than in adults. C. There's an increased risk of toxicity with use of topical agents. D. Protein binding of drugs is greater than in adults.

Correct Answer is C

Explanation

Choice A rationale:
While it’s true that infants have slower drug metabolism, this is generally due to liver immaturity, not kidney function.
Choice B rationale:
Absorption of oral medications in infants can be unpredictable due to their immature digestive systems.
Choice C rationale:
Infants do have an increased risk of toxicity with the use of topical agents because their skin is thinner and more permeable.
Choice D rationale:
Protein binding of drugs is actually less in infants than in adults, not greater.
