Maternal Newborn ATI Proctored Exam

Correct Answer: B

Rationale: The Lecithin/sphingomyelin (L/S) ratio is a test used to evaluate fetal lung maturity. An L/S ratio greater than 2:1 indicates fetal lung maturity. This test helps in determining the risk of respiratory distress syndrome in the newborn. Alpha-fetoprotein (AFP) is used in screening for neural tube defects, not for assessing lung maturity. The Kleihauer-Betke test is used to detect fetal-maternal hemorrhage, not fetal lung maturity. The Indirect Coombs' test is used to identify the presence of antibodies in the mother's blood that could attack fetal red blood cells, not for assessing lung maturity.

Correct Answer: D

Rationale: A contraction stress test (CST) is performed to assess how the fetus responds to the stress of contractions. Indications for this test include decreased fetal movement, intrauterine growth restriction (IUGR), and postmaturity. These conditions may warrant the need for a CST to evaluate fetal well-being and determine appropriate management. Therefore, all of the above options are correct indications for a contraction stress test. Options A, B, and C are incorrect because they are all valid reasons for performing a CST in a pregnant client.

Correct Answer: C

Rationale: When discussing intermittent fetal heart monitoring, it is crucial to count the fetal heart rate after a contraction to determine baseline changes. This practice allows for the assessment of variations in the fetal heart rate pattern associated with uterine contractions. Monitoring the fetal heart rate after contractions provides valuable insights into fetal well-being and potential distress. Option A is incorrect because determining the baseline involves assessing the fetal heart rate over a more extended period. Option B is incorrect as auscultation every 5 minutes during the active phase of the first stage of labor is too frequent for intermittent monitoring. Option D is incorrect as auscultating the fetal heart rate every 30 minutes during the second stage of labor is too infrequent for proper monitoring of fetal well-being.

Correct Answer: B

Rationale: Corrected Question: When caring for a client receiving nifedipine for prevention of preterm labor, the nurse should monitor the client for which of the following manifestations? Rationale: Nifedipine, a calcium channel blocker, causes vasodilation, potentially leading to a decrease in blood pressure and side effects such as dizziness. Monitoring for dizziness is essential to ensure the client's safety and well-being during treatment. Choices A, C, and D are incorrect as they are not typically associated with nifedipine use for preventing preterm labor. Blood-tinged sputum may indicate other conditions like pulmonary issues, pallor could suggest anemia or circulatory problems, and somnolence is not a common side effect of nifedipine.

Correct Answer: B

Rationale: A weight gain of 3.6 kg (8 lb) in the first trimester is excessive and should be reported to the provider for further evaluation. Excessive weight gain in the first trimester can be a sign of potential issues that need monitoring and intervention to ensure the well-being of both the mother and the baby. Choices A, C, and D represent weight gains that are within normal ranges for the respective trimesters and do not raise immediate concerns for reporting to the provider.
