What are the proper steps for topical medications to ensure absorption?

• A. Clean/dry skin, apply a thin even layer to intact skin, avoid broken skin, and follow order for coverage.
• B. Apply a thick layer to moist skin, include broken skin, and ignore order for coverage.
• C. Rub vigorously until skin is red.
• D. Apply to mucous membranes.

Answer: (A)

Topical meds absorb best when the skin is prepared and the medication is applied in a controlled, surface-only way. Start with clean, dry, intact skin so oils, dirt, and moisture don’t interfere with contact. Apply a thin, even layer rather than a thick one so the drug can evenly contact the skin and be absorbed at a steady rate. Avoid applying to broken skin—damaged areas can lead to unpredictable absorption and irritation or systemic effects. Do not apply to mucous membranes, as they are more permeable and require different Instructions. Finally, follow the prescribed method for coverage so the medication isn’t wiped off or compromised by dressings or improper layering.
