ATI OB Obstetrics RN 300 Exam Questions
Extract:
A nurse in a prenatal clinic is caring for a client who is at 38 weeks of gestation and reports heavy, red vaginal bleeding. The bleeding started spontaneously in the morning and is not accompanied by contractions. The client is not in distress and she states that she can 'feel the baby moving.' An ultrasound is scheduled STAT.
Question 1 of 5
The nurse should explain to the client that the purpose of the ultrasound is to determine which of the following?
Correct Answer: C
Rationale: The correct answer is C: Location of the placenta. Ultrasound is used to assess the placental location, which is crucial for monitoring the health of the fetus and preventing complications like placenta previa.
Choice A is incorrect because viability is usually determined through other means like fetal heart rate.
Choice B, biparietal diameter, is a measurement used to estimate fetal size, not the purpose of the ultrasound.
Choice D, fetal lung maturity, is typically assessed through amniocentesis or other tests, not ultrasound.
