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."

Answer and Explanation

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.

A. May 17 B. May 13 C. May 3 D. May 20

Correct Answer is A

Explanation

May 13. Nägele's Rule is used to calculate the estimated date of delivery (EDD) based on the first day of the last menstrual period (LMP). To use this rule, the nurse subtracts 3 months from the first day of the LMP and adds 7 days and 1 year.

For this client, the first day of her LMP was August 10. Subtracting 3 months gives us May 10. Adding 7 days gives us May 17. Adding 1 year gives us May 17, 2022. Therefore, the estimated date of delivery is May 17, 2022.

It is important to note that Nägele's Rule is an estimation, and not all pregnancies follow the typical 280-day gestational period. Other factors, such as irregular menstrual cycles, can affect the accuracy of the estimated date of delivery. The nurse should monitor the client's pregnancy and adjust the estimated date of delivery as needed based on ultrasound results and other clinical findings.
