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?

Choice A rationale:

The nurse should not measure the abdominal circumference at the level of the newborn's umbilicus every 12 hr because this action does not address the specific problem presented in the scenario, which is abdominal distention and bloody stools. Measuring abdominal circumference is typically done to assess for growth and may not provide valuable information in this situation.

Choice B rationale:

Inserting an orogastric decompression tube with low wall suction is the appropriate action for a newborn with abdominal distension and bloody stools. This intervention can help decompress the gastrointestinal tract, reducing abdominal distention, and possibly preventing further complications.

Choice C rationale:

Providing the newborn with an iron-rich formula containing vitamin B12 every 2 hr is not indicated based on the information provided in the scenario. The newborn's symptoms are suggestive of gastrointestinal issues, and this intervention may not address the underlying cause.

Choice D rationale:

Administering nitric oxide inhalation therapy to the newborn is not appropriate in this context. Nitric oxide inhalation therapy is typically used for conditions like persistent pulmonary hypertension in the newborn, and there is no indication for its use in this case.

Choice A rationale:
Bright, red vaginal discharge is not a typical manifestation of an ectopic pregnancy. Instead, it can be indicative of other conditions such as miscarriage or vaginal bleeding.

Choice B rationale:
A scaphoid abdomen is not a typical manifestation of an ectopic pregnancy. A scaphoid abdomen is seen in cases of diaphragmatic hernia, where the abdominal organs move into the chest cavity, leaving the abdomen with a sunken appearance.

Choice C rationale:
Elevated blood pressure is not a typical manifestation of an ectopic pregnancy. High blood pressure can be associated with conditions like preeclampsia but is not specifically linked to ectopic pregnancies.

Choice D rationale:
Sharp pelvic pain is a common manifestation of an ectopic pregnancy. As the fertilized egg implants outside the uterus, often in the fallopian tube, it can cause pain and discomfort.
