Maternal Fetal Monitoring Questions
Question 1 of 5
What procedure might the nurse perform to determine the presentation of the fetus?
Correct Answer: B
Rationale: The correct answer is B: ultrasound. Ultrasound is the most accurate and non-invasive method to determine the presentation of the fetus by visualizing the position of the baby in the womb. It allows the nurse to see if the fetus is in a cephalic (head-down) or breech (feet or buttocks down) position. This information is crucial for assessing the progress of labor and planning appropriate interventions. A: Vaginal exam is not typically used to determine fetal presentation as it does not provide a clear view of the baby's position. C: Palpation of contractions helps assess the strength and frequency of contractions but does not directly determine fetal presentation. D: Laboring person interview may provide valuable information about symptoms and history but does not offer direct insight into fetal presentation.
Question 2 of 5
A nurse is caring for a postpartum person during the fourth stage of labor. The nurse is assessing uterine involution to ensure that the uterus is returning to its prepregnancy size and position. Which finding is indicative of normal uterine involution during this stage?
Correct Answer: B
Rationale: The correct answer is B because during the fourth stage of labor, the uterine fundus should be firm and at the level of the umbilicus. This indicates proper involution as the uterus is contracting and reducing in size. Choice A is incorrect as the uterus should not be palpable at the level of the umbilicus during normal involution. Choice C is incorrect as the uterus should not be displaced to the right side of the abdomen. Choice D is incorrect as the uterus should not be above the level of the umbilicus, as this would suggest inadequate involution.
Question 3 of 5
A nurse is preparing to administer a medication to a birthing person with a history of hypertension. What is the nurse's priority assessment before administering this medication?
Correct Answer: A
Rationale: The correct answer is A: Blood pressure and pulse rate. For a birthing person with a history of hypertension, it is crucial to assess their blood pressure and pulse rate before administering medication to ensure the medication does not exacerbate their hypertension. Monitoring these vital signs helps in determining the appropriateness and safety of the medication. Summary: - Choice B is incorrect because respiratory rate and oxygen saturation are not the priority assessments for a person with a history of hypertension. - Choice C is incorrect as temperature and urine output are not directly related to assessing the risk of exacerbating hypertension. - Choice D is incorrect as oxygen saturation and urine output are not the primary indicators of medication safety for someone with hypertension.
Question 4 of 5
What is the recommended frequency for assessing maternal vital signs during the first hour after delivery?
Correct Answer: A
Rationale: The correct answer is A (every 15 minutes) because immediate postpartum assessment is crucial for early detection of complications. Monitoring vital signs every 15 minutes allows for prompt identification of issues like hemorrhage or infection. Choice B (every 30 minutes) may lead to a delayed response to critical changes. Choice C (once, then hourly) may miss rapid changes in the first hour. Choice D (once, then every 4 hours) is too infrequent for the critical postpartum period. Regular monitoring is essential for ensuring maternal safety.
Question 5 of 5
What is the primary purpose of a non-stress test (NST) during pregnancy?
Correct Answer: C
Rationale: The correct answer is C: to assess fetal heart rate accelerations. An NST is used to monitor the baby's heart rate and movement to ensure adequate oxygen supply. Fetal heart rate accelerations indicate a healthy, responsive baby. Assessing heart rate variability (A) is important but not the primary purpose. Evaluating fetal well-being (B) is broad and doesn't capture the specific focus on heart rate accelerations. Assessing maternal well-being (D) is not the purpose of an NST.
