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

The correct answer is choice a. Provide the client with a cool sitz bath.

Choice A rationale:

A cool sitz bath can help reduce swelling and provide pain relief for a client with a fourth-degree laceration of the perineum. Cooling the area can also help minimize inflammation and promote healing.

Choice B rationale:

Methylergonovine is typically used to prevent or treat postpartum hemorrhage by causing uterine contractions. It is not indicated for the management of perineal lacerations.

Choice C rationale:

Applying a moist, warm compress to the perineum is not recommended immediately postpartum for a fourth-degree laceration, as it can increase swelling and discomfort. Cool treatments are preferred initially.

Choice D rationale:

Applying povidone-iodine to the perineum is not a standard practice for managing perineal lacerations. It can cause irritation and is not necessary for wound care in this context.

A. The mother and the father are both Rh positive. B. The mother is Rh positive and the father is Rh negative. C. The mother is Rh negative and the father is Rh positive. D. The mother and the father are both Rh negative.

Correct Answer is C

Explanation

Choice A rationale:

If both the mother and the father are Rh positive, there is no risk of hemolytic disease in the newborn due to Rh incompatibility. Hemolytic disease of the newborn occurs when the mother is Rh negative and the father is Rh positive.

Choice B rationale:

When the mother is Rh positive and the father is Rh negative, there is no risk of hemolytic disease in the newborn. Hemolytic disease results from Rh incompatibility, which occurs when the mother is Rh negative, and the father is Rh positive.

Choice C rationale:

This is the correct answer. Hemolytic disease of the newborn occurs when the mother is Rh negative, and the father is Rh positive. In such cases, the baby may inherit the Rh factor from the father, leading to Rh incompatibility between the mother and the baby's blood, potentially causing hemolytic disease.

Choice D rationale:

If both the mother and the father are Rh negative, there is no risk of hemolytic disease in the newborn due to Rh incompatibility. Hemolytic disease of the newborn occurs when the mother is Rh negative and the father is Rh positive.
