Practice Question

A nurse is reviewing the mechanisms of action for medications prescribed to a client who has acne vulgaris. Which of the following medications should the nurse understand as having keratolytic effects that aid in the removal of excess skin cells?

Answer Choices:

Correct Answer:

Tretinoin

Rationale:

🖋️ Tretinoin is a topical retinoid that has strong keratolytic properties, meaning it promotes shedding of excess keratinized skin cells.

🖋️ This action prevents follicular plugging, which is a key mechanism in acne vulgaris development.

🖋️ By increasing cell turnover, tretinoin reduces formation of comedones and improves skin texture.

🖋️ Antibiotics target bacteria, antihistamines target allergies, and steroids reduce inflammation but do not remove keratin plugs.

🖋️ Understanding medication mechanisms allows nurses to reinforce effective and appropriate acne treatment.
