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 C
Explanation
Choice A rationale
Umbilical cord compression typically causes variable decelerations in fetal heart rate, not accelerations. Accelerations are not related to cord compression but rather to other factors.
Choice B rationale
Placental uterine insufficiency leads to late decelerations rather than accelerations in fetal heart rate. Accelerations indicate adequate oxygenation, whereas insufficiency impairs fetal oxygenation.
Choice C rationale
Accelerations with fetal movement are a positive sign, indicating the fetus's well-being and appropriate response to stimuli. Normal accelerations last for at least 15 seconds and rise by 15 beats per minute.
Choice D rationale
Ominous signs in fetal monitoring include persistent late decelerations, severe bradycardia, and prolonged decelerations. Accelerations, however, are reassuring and do not warrant concern.
Correct Answer is D
Explanation
Choice A rationale
Folic acid does not reduce the risk of preeclampsia. Instead, it is crucial for preventing neural tube defects in the developing fetus during early pregnancy.
Choice B rationale
While folic acid can improve overall nutrition, its primary importance during pregnancy is in preventing neural tube defects by aiding in proper neural development.
Choice C rationale
Folic acid does not prevent patent ductus arteriosus. It is specifically recommended to prevent neural tube defects like spina bifida by supporting proper neural tube closure.
Choice D rationale
Folic acid is essential for preventing neural tube defects such as spina bifida. It helps ensure the proper closure of the neural tube during early fetal development, reducing the risk of these defects.
