A multiparous client with active herpes lesions is admitted to the unit with spontaneous rupture of membranes. Which action should the nurse take?

A. Cover the lesion with a dressing: While protecting the lesions can reduce contamination, it does not prevent neonatal exposure during vaginal delivery, which is the primary concern. B. Administer penicillin: Penicillin treats bacterial infections such as group B streptococcus, not herpes simplex virus. It does not prevent neonatal herpes transmission. C. Obtain blood cultures: Blood cultures are indicated if systemic infection is suspected, but they do not address the immediate risk of neonatal herpes transmission during delivery. D. Prepare for a cesarean section: Active genital herpes lesions at the time of labor significantly increase the risk of neonatal herpes infection. Cesarean delivery before the onset of labor or rupture of membranes is the recommended intervention to minimize vertical transmission to the newborn.
