A nurse is teaching a newly licensed nurse about the uses of ultrasonography in the first trimester of pregnancy. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
"Ultrasound is used to determine gestational age in the first trimester.".
"Ultrasound is used to perform a biophysical profile in the first trimester.".
"Ultrasound is used to observe for placental maturity in the first trimester.".
"Ultrasound is used to detect intrauterine growth restriction in the first trimester.".
The Correct Answer is A
Choice A rationale:
Determining gestational age in the first trimester is a common and important use of ultrasound. It helps confirm the estimated due date and monitor the fetus's growth and development.
Choice B rationale:
Performing a biophysical profile in the first trimester is not a common use of ultrasound. Biophysical profiles are usually performed in the second or third trimester to assess fetal well-being.
Choice C rationale:
Observing placental maturity in the first trimester is not a standard use of ultrasound. Placental maturity is typically assessed later in pregnancy, especially in the third trimester.
Choice D rationale:
Detecting intrauterine growth restriction in the first trimester is not a primary use of ultrasound. Intrauterine growth restriction is more commonly assessed in the later stages of pregnancy when fetal growth is a concern.

Correct Answer is C
Explanation
Listeriosis is a foodborne illness that can have severe consequences during pregnancy. To minimize the risk of listeriosis, a pregnant client should avoid certain foods that are more likely to be contaminated with the bacteria Listeria. The correct statement that indicates an understanding of the teaching is:
C) "I can eat grilled chicken on a bun at lunchtime."
Grilled chicken is a safe option, and as long as it's properly cooked, it's a suitable choice during pregnancy. The other options are not recommended during pregnancy:
A) Soft cheeses, like Brie or feta, can carry a risk of Listeria contamination, so they should be avoided.
B) Seafood salad from the grocery store may not be safe as it could contain seafood that's been sitting at improper temperatures, which can increase the risk of foodborne illness.
D) Hot dogs can also be a risk as they are often not served steaming hot, which is necessary to kill any potential Listeria contamination.
Correct Answer is C
Explanation
The correct answer is c. Cleanse the newborn immediately after delivery. This is because cleansing the newborn can reduce the risk of HIV transmission through exposure to maternal blood or fluids. The other options are not appropriate for the following reasons:
a. Administer IV antibiotics to the newborn. This is not necessary unless the newborn has signs of infection or sepsis. Antibiotics do not prevent or treat HIV infection.
b. Encourage the mother to breastfeed her newborn. This is contraindicated for mothers with HIV, as breastfeeding can transmit the virus to the infant. Mothers with HIV should avoid breastfeeding and use formula or donor milk instead.
d. Initiate contact precautions for the newborn. This is not required for newborns exposed to HIV, as HIV is not transmitted by casual contact. Standard precautions are sufficient to prevent the spread of HIV and other bloodborne pathogens.
