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 B
Explanation
Pour warm water over the client's perineum. The nurse should first attempt non-invasive measures to treat bladder distention, such as pouring warm water over the client's perineum, to promote relaxation of the perineal muscles and increase urinary flow. If this measure is unsuccessful, the nurse may need to proceed with catheterization. However, catheterization can increase the client's risk for infection and trauma, so it should not be the first-line intervention. A sitz bath can also be helpful in treating bladder distention but is not as effective as warm water application directly to the perineum. Assisting the client to the bathroom is not indicated since the client is experiencing bladder distention, which can lead to difficulty emptying the bladder.
Correct Answer is A
Explanation
The correct answer is choice A: Fortified soy milk. Vitamin B12 is found in animal products, so vegans are at risk of vitamin B12 deficiency. Fortified soy milk is a good source of vitamin B12 for vegans.
Choice B, brown rice, choice C, fresh citrus fruits, and choice D, raw carrots, are not good sources of vitamin B12.
