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

a) Encouraging self-application is beneficial in some cases, but it is not always appropriate. The nurse must ensure the medication is applied correctly and safely, especially if the patient has mobility or cognitive impairments. b) Wearing treatment gloves is important when handling certain medications, but it is not required for all topical applications. Some medications, such as nitroglycerin ointment, require gloves to prevent nurse exposure, but others do not. c) Changing gloves between skin preparation and medication application is not a universal requirement. In most cases, the same pair of gloves can be used unless contamination occurs. d) Performing effective hand hygiene before and after applying the medication is the most essential action to prevent infection and cross-contamination.
