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
Inadequate weight gain during pregnancy can lead to intrauterine growth restriction (IUGR), where the fetus does not grow as expected.
Choice B rationale
Excess weight gain is not solely due to overeating; it can result from edema, gestational diabetes, or other metabolic factors.
Choice C rationale
Height is a factor in determining a pregnant woman’s target weight range, influencing the overall recommended weight gain.
Choice D rationale
Obese women have higher risks of complications, including gestational diabetes and hypertensive disorders, differing from normal weight women.
Correct Answer is C
Explanation
Choice A rationale
Uterine contractions (powers) are essential for cervical dilation and fetal descent. They are involuntary smooth muscle contractions regulated by oxytocin and prostaglandins.
Choice B rationale
The fetus (passenger) significantly influences labor progression. Fetal size, position, and presentation affect the ease of passage through the birth canal.
Choice C rationale
Pressure is not considered one of the five Ps affecting labor and birth. The five Ps are powers, passenger, passageway, position, and psychological response.
Choice D rationale
The birth canal (passageway) includes the bony pelvis and soft tissues, which must adapt to allow the fetus to pass through during labor.
