During the first trimester of pregnancy, a client who was treated for genital herpes with acyclovir prior to this pregnancy tells the practical nurse (PN) that she is experiencing an episode of genital herpes. Which nursing intervention has the highest priority?

A. Assess her feelings about therapeutic abortions in the event the infant has been affected. - While important to consider potential outcomes, immediate care involves preventing transmission and managing the current outbreak. B. Identify current sexual partners so that they can be evaluated and treated for genital herpes if necessary. - Contact tracing is important but not the highest priority in managing the current outbreak. C. Instruct her to avoid sexual intercourse while active, visible lesions are present. - This is crucial to prevent transmission of the herpes virus to the sexual partner and to reduce the risk of complications for the pregnancy. D. Determine if the client has taken acyclovir for this outbreak of genital herpes. - While important for understanding the treatment history, instructing the client on preventive measures has a higher priority.
