A client’s maternal serum alpha-fetoprotein level is elevated at 17 weeks.
What condition should the nurse identify as the likely cause of this increase?
Multiple gestation.
Fetal hypoxia.
Down syndrome.
Neural tube defect.
The Correct Answer is D
Choice A rationale
While multiple gestation can cause an increase in maternal serum alpha-fetoprotein (MS-AFP) levels, it is not the most likely cause of an elevated MS-AFP level at 17 weeks.
Choice B rationale
Fetal hypoxia, or lack of oxygen to the fetus, is not typically associated with an increase in MSAFP levels.
Choice C rationale
Down syndrome is typically associated with lower, not higher, levels of MS-AFP891011.
Choice D rationale
An elevated level of MS-AFP at 17 weeks is most commonly associated with a neural tube defect. Neural tube defects are birth defects of the brain, spine, or spinal cord that occur during the first month of pregnancy.

Correct Answer is B
Explanation
Choice A rationale
While it is true that the ointment can help prevent certain types of infections, it is not specifically intended to prevent herpes infection. Herpes is a viral infection, and the ointment is an antibiotic, which is used to prevent bacterial infections.
Choice B rationale
The primary purpose of eye ointment is to protect newborns from serious eye infections caused by common bacteria. Mothers who have a sexually transmitted infection (STI) can pass it to their newborns during childbirth, putting them at risk for an eye infection known as ophthalmia neonatorum (ON)3.
Choice C rationale
The ointment does not serve to clear the infant’s vision. It is applied to the eyes to prevent bacterial infections, not to improve or alter the infant’s vision.
Choice D rationale
The ointment is not used to dilate the pupil to visualize the red reflex. The red reflex is a reflection from the lining of the eye that is often observed when looking at the pupil, but this is not related to the application of the ointment.
Correct Answer is B
Explanation
Choice A rationale
While contact precautions can be important in managing some infections, they are not the primary reason for hospitalization in the case of PID891011.
Choice B rationale
Hospitalization for PID is often recommended for the administration of a supervised parenteral antibiotic protocol. This allows for the direct administration of antibiotics into the bloodstream, which can be more effective in severe cases.
Choice C rationale
The Jarisch-Herxheimer reaction is a reaction to endotoxin-like products released by the death of harmful microorganisms within the body during antibiotic treatment. It is not a primary reason for hospitalization in the treatment of PID891011.
Choice D rationale
While the collection of serial anaerobic cultures of vaginal discharge can be part of the diagnostic process for PID, it is not the primary reason for hospitalization.
