Which of the following is NOT a proper procedure when applying medication to the skin?

Applying medication to the skin involves adhering to specific protocols to ensure safety and efficacy. When considering the application of topical medications, it's essential to apply them in a manner that promotes effectiveness and minimizes potential irritation.

Applying medication in a thick coat is generally not recommended because it can lead to improper absorption and may cause skin irritation or adverse reactions. Medications are often formulated to be used in a thin, even layer to allow for proper absorption into the skin. A thicker application does not necessarily enhance the therapeutic effect and can sometimes create a barrier that prevents the medication from working effectively.

In contrast, washing away previous medication ensures that any remnants or residues do not interfere with the new application. Using fingertips for applying lotion or ointment allows for more precise application and can help with the absorption of the medication. Lastly, the practice of washing hands before and after administering medication is crucial for maintaining proper hygiene and preventing the spread of infection.
