Question 5 of 5
A client with a bacterial skin infection is being taught home care for treatment of this infection. Which statement by the client indicates a need for further teaching?
Correct Answer: A
Rationale: The statement by the client that, 'I may stop using the topical antibiotic when the lesions disappear,' indicates the need for further teaching. The antibiotic should be used for the time prescribed and not just until the lesions seem to be resolved. Clients should be taught to remove crusts before applying the medication to improve absorption. If signs of systemic disease occur, the client should contact the provider since oral antibiotics may be necessary. Covering the lesions will help prevent spread to others.
