A primigravida has just delivered a healthy infant girl. The nurse is about to administer erythromycin ointment in the infant's eyes when the mother asks, "What is that medicine for?" The nurse responds:
a. "It is an eye ointment to help your baby see you better."
b. "It is to protect your baby from contracting herpes from your vaginal tract."
c. "Erythromycin is given prophylactically to prevent a gonorrheal infection."
d. "This medicine will protect your baby's eyes from drying out over the next few days."
ANS: C
With the prophylactic use of erythromycin, the incidence of gonococcal conjunctivitis has declined to less than 0.5%. Eye prophylaxis is administered at or shortly after birth to prevent ophthalmia neonatorum. Erythromycin has no bearing on enhancing vision, is used to prevent an infection caused by gonorrhea, not herpes, and is not used for eye lubrication.
