Maternal Newborn ATI Proctored Exam Questions
Question 1 of 5
A client at 8 weeks of gestation with iron deficiency anemia is prescribed iron supplements. Which beverage should the nurse reinforce the client to take the supplements with for better absorption?
Correct Answer: D
Rationale: The correct answer is D: Orange juice. Vitamin C enhances iron absorption by converting non-heme iron to a more absorbable form. The acidity in orange juice aids in this process. Ice water (choice A) does not contain any nutrients to enhance iron absorption. Low-fat or whole milk (choice B) contains calcium, which can inhibit iron absorption. Tea or coffee (choice C) contains tannins that can also inhibit iron absorption. In summary, orange juice is the best choice due to its vitamin C content that helps improve iron absorption.
Question 2 of 5
During preterm labor, a client is scheduled for an amniocentesis. The nurse should review which of the following tests to assess fetal lung maturity?
Correct Answer: B
Rationale: The correct answer is B: Lecithin/sphingomyelin (L/S) ratio. This test is used to assess fetal lung maturity by determining the ratio of two substances present in amniotic fluid. An L/S ratio of 2:1 or higher indicates mature fetal lungs, reducing the risk of respiratory distress syndrome in preterm infants. A: Alpha-fetoprotein (AFP) is used to screen for neural tube defects, not fetal lung maturity. C: Kleihauer-Betke test is used to detect fetal-maternal hemorrhage. D: Indirect Coombs' test is used to detect antibodies in maternal blood that may attack fetal red blood cells, not assess fetal lung maturity. In summary, the L/S ratio test is the most appropriate choice to assess fetal lung maturity during preterm labor, as it directly correlates with the development of the fetal lungs.
Question 3 of 5
During a nonstress test for a pregnant client, a nurse uses an acoustic vibration device. The client inquires about its purpose. Which response should the nurse provide?
Correct Answer: D
Rationale: The correct answer is D because the acoustic vibration device is used during a nonstress test to wake up a sleeping fetus, ensuring that the baby is active and responsive during the test. This helps to assess the baby's well-being and monitor its heart rate patterns. Choice A is incorrect as the device does not stimulate uterine contractions. Choice B is incorrect as it does not decrease the incidence of contractions. Choice C is incorrect as the device does not lull the fetus to sleep, but rather ensures the fetus is awake and moving during the test.
Question 4 of 5
A client who is at 22 weeks gestation is being educated by a nurse about the amniocentesis procedure. Which of the following statements should the nurse make?
Correct Answer: C
Rationale: The correct answer is C: You should empty your bladder before the procedure. This is important because a full bladder can obstruct the visualization of the fetus during amniocentesis. By emptying the bladder, the uterus is better positioned for the procedure, making it safer and more effective. Explanation: 1. A (You will lie on your right side during the procedure) is incorrect because the position during amniocentesis is typically on the back or slightly tilted to the left. 2. B (You should not eat anything for 24 hours before the procedure) is incorrect as fasting is not required for amniocentesis. 3. D (The test is performed to determine gestational age) is incorrect as amniocentesis is used to detect genetic abnormalities, not gestational age.
Question 5 of 5
A client who is pregnant is scheduled for a contraction stress test (CST). Which of the following findings are indications for this procedure? (Select all that apply)
Correct Answer: D
Rationale: The correct answer is D, All of the Above. 1. Decreased fetal movement indicates fetal distress, necessitating CST. 2. IUGR implies potential placental insufficiency, requiring CST evaluation. 3. Postmaturity increases risk of placental insufficiency, warranting CST. Other choices are incorrect as they do not directly indicate the need for CST in a pregnant client.
