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 observe for placental maturity in the first trimester."
"Ultrasound is used to perform a biophysical profile in the first trimester."
"Ultrasound is used to determine gestational age in the first trimester."
"Ultrasound is used to detect intrauterine growth restriction in the first trimester."
The Correct Answer is C
The correct answer is choice C. Ultrasonography is a diagnostic tool used during pregnancy to visualize the fetus and the maternal reproductive organs. In the first trimester of pregnancy, it is primarily used to determine gestational age, confirm the presence of an intrauterine pregnancy, and assess for fetal viability. It can also be used to identify multiple gestations, evaluate for ectopic pregnancy, and detect certain fetal anomalies. Ultrasound is not typically used to observe for placental maturity or to perform a biophysical profile in the first trimester. Intrauterine growth restriction is typically assessed later in pregnancy using serial ultrasound measurements.

Correct Answer is D
Explanation
"Transmission can occur via the saliva and urine of the newborn." Maternal cytomegalovirus (CMV) is a viral infection that can be transmitted to the fetus during pregnancy or to the newborn during delivery or through breast milk. Lesions on the mother's genitalia are associated with herpes simplex virus, not CMV. Mothers with active CMV infection may not show any symptoms, and there is no specific prophylactic treatment with acyclovir for CMV infection. Airborne precautions are not necessary for newborns with CMV infection since the virus is primarily spread through contact with body fluids, such as saliva and urine.
Correct Answer is D
Explanation
: Rh-positive blood test results. Rho(D) immune globulin is indicated for Rh-negative women who are pregnant and for those who have had a miscarriage, ectopic pregnancy, or induced abortion. It is also indicated for Rh-negative women who give birth to Rh-positive infants. The administration of Rho(D) immune globulin prevents the Rh-negative mother from forming antibodies against Rh-positive fetal cells that may have entered her bloodstream.
Choice A, prescription for an amniocentesis, is not an indication for the administration of Rho(D) immune globulin. Choice B, anemia, and choice C, hyperemesis gravidarum, are also not indications for the administration of Rho(D) immune globulin.
