A nurse is caring for a client who has herpes zoster. Which of the following actions should the nurse take?

A. Individuals who have had chickenpox or have been vaccinated against varicella generally have immunity and are not at risk from exposure to herpes zoster. Visitors who are not immune (e.g., pregnant women, immunocompromised individuals, or those without prior varicella exposure) should avoid contact instead. B. Acyclovir is an antiviral medication commonly prescribed for herpes zoster. It helps reduce viral replication, decreases the severity and duration of symptoms, promotes faster healing of lesions, and lowers the risk of complications such as postherpetic neuralgia, especially when started early. C. Herpes zoster lesions are typically managed by keeping them clean and dry, but routine application of dry sterile gauze is not required unless there is drainage or risk of secondary infection. Loose, nonadherent coverings may be used if needed for comfort or protection. D. Topical corticosteroids are not routinely recommended for herpes zoster lesions because they can delay healing and increase the risk of secondary infection. Pain management is usually addressed with antivirals, analgesics, and sometimes systemic medications rather than topical steroids.
