A primipara at 20-weeks gestation is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?
Chromosomal abnormalities
Sex and size of the infant
Lecithin-sphingomyelin ratio
Fetal growth and gestational age.
The Correct Answer is D
A. Chromosomal abnormalities:
While an ultrasound can sometimes identify structural abnormalities, it's not the primary tool for detecting chromosomal abnormalities. Genetic testing or procedures like amniocentesis are more specific for this purpose.
B. Sex and size of the infant:
An ultrasound is indeed used to determine the sex of the baby and assess its size and growth.
C. Lecithin-sphingomyelin ratio:
The lecithin-sphingomyelin ratio is typically assessed in tests related to fetal lung maturity, which is not the primary purpose of a routine ultrasound.
D. Fetal growth and gestational age:
This is one of the primary purposes of a routine ultrasound during pregnancy. It helps evaluate the baby's growth and ensures it aligns with the expected gestational age.

Correct Answer is ["C","D","E"]
Explanation
A. Place client in a negative pressure room:HIV is not an airborne disease, and clients with HIV do not require isolation in a negative pressure room. Standard precautions are sufficient to prevent transmission.
B. Implement droplet precautions:HIV is not transmitted via droplets. It is transmitted through contact with blood, certain body fluids, or perinatal exposure. Droplet precautions are not indicated.
C. Encourage the mother to bottle-feed: HIV can be transmitted through breast milk. To prevent vertical transmission postpartum, mothers with HIV are advised to avoid breastfeeding and to use formula or bottle-feed instead.
D. Give antiviral medication intravenously: Intrapartum IV zidovudine should be administered in the following situations: (a) HIV RNA >1,000 copies/mL, (b) unknown HIV RNA, (c) known or suspected lack of adherence since the last HIV RNA result, or (d) a positive expedited antigen/antibody HIV test result during labor (AI).
E. Use standard precautions:Standard precautions are the appropriate infection control measures for caring for clients with HIV. This includes wearing gloves, practicing proper hand hygiene, and avoiding contact with the client's blood and other potentially infectious fluids.
Correct Answer is B
Explanation
A. Bleeding tendencies:
Bleeding tendencies are not typically a priority immediately after birth unless there is a specific indication. Newborns are not at immediate risk for bleeding unless there are underlying conditions.
B. Heat loss:
Heat loss is a significant concern for newborns. Maintaining an adequate temperature is crucial to prevent hypothermia, which can lead to complications.
C. Hypoglycemia:
While monitoring blood glucose is important in the newborn, it may not be the most immediate concern within the first minutes after delivery. Stabilizing the newborn's temperature and initiating breathing are usually higher priorities.
D. Fluid balance:
Fluid balance is essential, but the initial focus is often on establishing respirations and maintaining temperature. Fluids may be administered as needed based on the clinical assessment.
