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: The correct answer is D: All of the Above. Multiple risk factors can contribute to preterm labor, including urinary tract infection, multifetal pregnancy, and oligohydramnios. These factors can lead to the uterus being irritated or overstimulated, potentially triggering early labor. Urinary tract infections can cause inflammation and contractions, multifetal pregnancies have a higher risk of preterm labor due to increased uterine stretching, and oligohydramnios can lead to poor fetal growth and premature contractions. Therefore, clients presenting with these conditions require close monitoring and management to prevent preterm birth. Choices A, B, and C are all correct risk factors for preterm labor, making option D the correct answer.

Correct Answer: A

Rationale: In cases of placenta previa with active bleeding at 32 weeks of gestation, Betamethasone is prescribed to accelerate fetal lung maturity in anticipation of potential preterm delivery. This medication helps in reducing the risk of respiratory distress syndrome in the newborn, which is crucial in managing such high-risk pregnancies. Indomethacin is a nonsteroidal anti-inflammatory drug not indicated in this scenario and may be contraindicated due to its effects on platelet function and potential risk of bleeding. Nifedipine is a calcium channel blocker used for conditions like preterm labor or hypertension, not specifically for placenta previa with active bleeding. Methylergonovine is a uterotonic drug used to prevent or control postpartum hemorrhage, not indicated for placenta previa with active bleeding.

Correct Answer: D

Rationale: The correct answer is D. To prevent TORCH infections during pregnancy, it is essential for clients to avoid consuming undercooked meat, as it can be a potential source of toxoplasmosis. This infection, along with others in the TORCH group, can pose risks to the fetus, making it crucial for pregnant individuals to follow proper food safety practices. Choices A, B, and C are incorrect because seeking an immunization against rubella, receiving prophylactic treatment for cytomegalovirus, and avoiding crowded places are not directly related to preventing TORCH infections through food safety measures.

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.
