Pregnancy Assessment Questions Questions
Question 1 of 5
What is the purpose of initiating contractions in a contraction stress test (CST)?
Correct Answer: D
Rationale: The purpose of initiating contractions in a contraction stress test (CST) is to apply a stressful stimulus to the fetus to assess its response to stress, mimicking the stress of labor. This helps evaluate fetal well-being by monitoring the fetal heart rate during contractions. A: Increasing placental blood flow is not the primary purpose of CST. B: Identifying fetal acceleration patterns is not the main goal of CST. C: Determining the degree of fetal activity is not the primary objective of CST. The correct answer is D as it reflects the main purpose of initiating contractions in a CST.
Question 2 of 5
A pregnant patient has received the results of her triple-screen testing and it is positive. She provides you with a copy of the test results that she obtained from the lab. What would the nurse anticipate as being implemented in the patient's plan of care?
Correct Answer: B
Rationale: The correct answer is B: Refer to the physician for additional testing. When a triple-screen test is positive in a pregnant patient, it indicates an increased risk of certain conditions such as neural tube defects or chromosomal abnormalities. Therefore, the appropriate course of action is to refer the patient to a physician for further diagnostic testing, such as amniocentesis or ultrasound, to confirm or rule out these conditions. Choice A is incorrect because a positive result on a triple-screen test does not indicate that results are normal; it suggests the need for further investigation. Choice C is incorrect because validating the results with the lab facility does not address the need for additional diagnostic testing. Choice D is incorrect because waiting 2 weeks to repeat the test and returning for a regular prenatal visit may delay necessary interventions or treatment for the patient.
Question 3 of 5
For which patient would an L/S ratio of 2:1 potentially be considered abnormal?
Correct Answer: B
Rationale: The correct answer is B. An L/S ratio of 2:1 is indicative of fetal lung maturity. This means that the lungs of the fetus are likely mature enough to function outside the womb. In choice B, the patient is 24 years old with diabetes, a condition that can affect fetal lung development, making it crucial to assess lung maturity. Choice A is less likely to have abnormal lung maturity at 38 weeks' gestation. Choice C, a 44-year-old gravida 6, para 5, is more likely to have mature fetal lungs due to multiple pregnancies. Choice D, an 18-year-old in early labor at term, may not necessarily have abnormal lung maturity as she is at term and in labor.
Question 4 of 5
A newly pregnant patient tells the nurse that she has irregular periods and is unsure of when she got pregnant. Scheduling an ultrasound is a standing prescription for the patient's health care provider. When is the best time for the nurse to schedule the patient's ultrasound?
Correct Answer: A
Rationale: The best time to schedule the ultrasound immediately is because in early pregnancy, it is crucial to confirm the gestational age, rule out ectopic pregnancy, and assess fetal viability. This allows for accurate dating, identification of potential complications, and timely interventions if needed. Waiting for 2, 4, or 6 weeks could delay necessary care and potentially compromise the well-being of the patient and the fetus. Early detection and management of any issues are essential in ensuring a healthy pregnancy outcome.
Question 5 of 5
A patient at 36 weeks gestation is undergoing a nonstress (NST) test. The nurse observes the fetal heart rate baseline at 135 beats per minute (bpm) and four nonepisodic patterns of the fetal heart rate reaching 160 bpm for periods of 20 to 25 seconds each. How will the nurse record these findings?
Correct Answer: C
Rationale: Step 1: The baseline fetal heart rate is 135 bpm, which is within the normal range of 110-160 bpm. Step 2: The four nonepisodic patterns of fetal heart rate reaching 160 bpm for 20-25 seconds each indicate accelerations, a positive sign. Step 3: A reactive NST requires at least two accelerations of the fetal heart rate within a 20-minute window, which this scenario meets. Step 4: Therefore, the nurse will record these findings as NST reactive, reassuring because the fetal heart rate responded appropriately to stimuli. Summary of Other Choices: A: NST positive, nonreassuring - Inaccurate, as the findings indicate a reassuring response. B: NST negative, reassuring - Incorrect, as the test results are actually reactive, not negative. D: NST nonreactive, nonreassuring - Wrong, as the test is reactive and reassuring, not nonreactive and nonreassuring.
