A new father wants to know what medication was put into his infant’s eyes and why it is needed.
How does the nurse explain the purpose of the erythromycin ophthalmic ointment?
This ointment prevents the infant’s eyelids from sticking together and helps the infant see.
This ophthalmic ointment prevents gonorrheal infection of the infant’s eyes, potentially acquired from the birth canal.
Erythromycin prevents potentially harmful exudate from invading the tear ducts of the infant’s eyes, leading to dry eyes.
Erythromycin ophthalmic ointment destroys an infectious exudate caused by Staphylococcus that could make the infant blind.
The Correct Answer is B
Choice A rationale
Erythromycin ophthalmic ointment does not prevent the infant's eyelids from sticking together; it is not its primary purpose and does not aid in vision enhancement.
Choice B rationale
Erythromycin ophthalmic ointment is used to prevent gonorrheal infection acquired during birth, protecting the infant’s eyes from potential infection that can cause blindness.
Choice C rationale
Erythromycin does not prevent exudate from invading the tear ducts, nor does it lead to dry eyes. Its primary function is antimicrobial.
Choice D rationale
Erythromycin ophthalmic ointment is not specific to Staphylococcus and does not directly destroy infectious exudate. It prevents infections like gonorrhea.

Correct Answer is A
Explanation
Choice A rationale
Meconium is produced by the fetal intestines. The intestines start to form meconium around the 16th week of gestation. Meconium is composed of shed cells, mucus, amniotic fluid, bile, and lanugo.
Choice B rationale
The placenta does not produce meconium. Its primary functions include nutrient transfer, gas exchange, and waste elimination, but it does not have the structures necessary for the production of meconium.
Choice C rationale
Amniotic fluid does not produce meconium. Amniotic fluid surrounds and protects the fetus but does not contain the components needed to create meconium. Instead, the fetus swallows and then excretes it into the intestines.
Choice D rationale
Fetal kidneys are responsible for filtering waste and producing urine, but they do not produce meconium. The production of meconium is a function of the intestines, not the kidneys.
