A father watching the admission of his newborn to the nursery notices that eye ointment is placed in the infant's eyes. He asks the nurse what is the purpose of the ointment. Which response by the nurse will best explain the purpose for administering the ointment?

A. "The ointment will prevent a herpes infection.": The eye ointment administered at birth is not specifically for herpes simplex virus. Herpes infections are rare and typically require other precautions and treatments. B. "The ointment will dilate the pupil so the red reflex can be visualized.": Pupil dilation is achieved with eye drops like tropicamide or cyclopentolate, not prophylactic eye ointment. The ointment does not affect the red reflex. C. "The ointment will clear the infant's vision.": Newborn eye ointment does not improve vision clarity; its purpose is preventive, not corrective or vision-enhancing. D. "The ointment will prevent eye infections.": Prophylactic ophthalmic ointment, commonly erythromycin, is applied to prevent neonatal eye infections, particularly those caused by Neisseria gonorrhoeae or Chlamydia trachomatis acquired during birth.
