When administering topical medications, which is an important nursing action?

The correct answer is D: Perform effective hand hygiene before and after applying the medication. This is important to prevent the spread of infection and maintain proper hygiene. Before applying the medication, clean hands reduce the risk of introducing harmful bacteria to the patient's skin. After applying the medication, hand hygiene prevents the nurse from spreading any potential contaminants to other surfaces or patients. Encouraging self-application (A) may lead to improper administration. Wearing gloves throughout (B) may not be necessary if proper hand hygiene is practiced. Changing gloves between prepping and applying (C) is not as crucial as maintaining clean hands.
