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 B
Explanation
Choice A rationale
Fetal movement felt by the pregnant woman is a presumptive sign of pregnancy, indicating probable fetal presence, but not definitive evidence.
Choice B rationale
Fetal heart rate noted on ultrasound is a positive sign of pregnancy, providing objective evidence of fetal existence within the uterus.
Choice C rationale
A positive pregnancy test indicates probable pregnancy due to hormonal presence, but it is not a definitive confirmation without further clinical evidence.
Choice D rationale
Braxton Hicks contractions are considered probable signs of pregnancy, as they indicate uterine activity without confirming the presence of a fetus.
Correct Answer is ["A","D","E"]
Explanation
Choice A rationale
Human chorionic gonadotropin (hCG) maintains the corpus luteum, ensuring the continued production of progesterone and estrogen, which are crucial for maintaining pregnancy.
Choice B rationale
Testosterone is not produced by the placenta during pregnancy, but is rather a male sex hormone produced primarily by the testes in males and small amounts by the ovaries in females.
Choice C rationale
Insulin is not produced by the placenta; it is a hormone produced by the pancreas that regulates blood glucose levels in the mother's body during pregnancy.
Choice D rationale
Estrogen produced by the placenta stimulates the growth of the uterus and helps regulate various functions essential for a healthy pregnancy.
Choice E rationale
Progesterone produced by the placenta helps maintain the uterine lining, reduces uterine contractions, and supports a favorable environment for fetal development throughout pregnancy.
