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:

Measuring the abdominal circumference at the level of the newborn's umbilicus every 12 hr is a critical action in this scenario. The newborn has necrotizing enterocolitis (NEC), a serious gastrointestinal condition, and measuring abdominal circumference can help monitor for changes in abdominal distention, which is a sign of NEC progression.

Choice B rationale:

Inserting an orogastric decompression tube with low wall suction may not be the most appropriate action for a newborn with NEC. While decompression tubes can be used in some cases of NEC, their insertion should be guided by specific clinical indications, and not all cases require them.

Choice C rationale:

Providing the newborn with an iron-rich formula containing vitamin B12 every 2 hr is not indicated for NEC. NEC requires specialized medical management and treatment, which may include bowel rest and other interventions, but providing iron-rich formula is not one of them.

Choice D rationale:

Administering nitric oxide inhalation therapy is not relevant to the management of NEC. Nitric oxide inhalation therapy is used for respiratory conditions, particularly persistent pulmonary hypertension of the newborn, and does not address the gastrointestinal issues seen in NEC.

A. Make a loud noise above the newborn. B. Touch the newborn's cheek with a finger. C. Tap the newborn's forehead with a finger. D. Turn the newborn's head to one side.

Correct Answer is A

Explanation

Choice A rationale:

The Moro reflex, also known as the startle reflex, is elicited by making a loud noise above the newborn, causing them to extend their arms and legs and then bringing them back to the body in a hugging motion. This reflex is a normal developmental response in term newborns.

Choice B rationale:
Touching the newborn's cheek with a finger elicits the rooting reflex, where the newborn turns their head toward the stimulus, searching for a nipple or object to suck. It is a different reflex and not the Moro reflex.

Choice C rationale:
Tapping the newborn's forehead with a finger does not elicit any specific reflex. This action is not related to the Moro reflex.

Choice D rationale:
Turning the newborn's head to one side elicits the asymmetric tonic neck reflex (ATNR), not the Moro reflex. In ATNR, when the head is turned to one side, the arm on that side extends while the opposite arm flexes.
