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.".

Answer and Explanation

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 A

Explanation

Choice A rationale:

The nurse should assess this client first as they are at 34 weeks of gestation and experiencing epigastric pain and headache. These symptoms could be indicative of preeclampsia, a serious pregnancy complication characterized by high blood pressure and organ damage. Preeclampsia requires immediate assessment and intervention to prevent further complications.

Choice B rationale:

Nausea and vomiting are common symptoms during the first trimester of pregnancy, and at 12 weeks of gestation, it is less likely to be a critical issue compared to potential preeclampsia.

Choice C rationale:

Painful urination may indicate a urinary tract infection, which can be important to assess and treat, but it is not as urgent as potential signs of preeclampsia in a client at 34 weeks of gestation.

Choice D rationale:

Cramping and spotting can be normal signs of impending labor, especially at 39 weeks of gestation. While it's important to assess this client, it is not the priority over potential preeclampsia in a client at 34 weeks of gestation with symptoms of epigastric pain and headache.

A. Perform vibroacoustic stimulation. B. Place the client in the Trendelenburg position. C. Conduct a vaginal exam. D. Collect a specimen for an indirect Coombs' test.

Correct Answer is A

Explanation

Choice A rationale:

Vibroacoustic stimulation is an appropriate action to perform during a nonstress test if there are no fetal heart rate accelerations. It involves using sound or vibration to stimulate the fetus, potentially eliciting the desired heart rate accelerations.

Choice B rationale:

Placing the client in the Trendelenburg position is not indicated in this situation. It may not benefit the fetus and is not a standard intervention for nonreactive nonstress test results.

Choice C rationale:

Conducting a vaginal exam is not relevant to the situation described in the question. A nonreactive nonstress test does not require a vaginal exam.

Choice D rationale:

Collecting a specimen for an indirect Coombs test is not necessary for this scenario. The test result would not provide information relevant to the nonreactive nonstress test.
