Correct Answer: D

Rationale: Infections such as gonorrhea, chlamydia, and HIV can be treated during labor or immediately following birth to prevent transmission to the newborn. It is crucial to identify and treat these infections promptly to reduce the risk of vertical transmission to the infant. Therefore, all the given options are correct as they can be treated during labor or immediately following birth to prevent transmission to the newborn. Other choices are incorrect because only gonorrhea, chlamydia, and HIV can be effectively treated during labor or immediately after birth to prevent vertical transmission.

Correct Answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid deficiency during pregnancy can lead to neural tube defects in the fetus, affecting the brain, spine, or spinal cord development. Iron deficiency anemia (choice A) is not directly related to folic acid deficiency. Poor bone formation (choice B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (choice C) refers to a baby with excessive birth weight and is not a typical outcome of folic acid deficiency in pregnancy. Therefore, it is crucial for individuals of childbearing age to take recommended folic acid supplements to prevent neural tube defects.

Correct Answer: D

Rationale: Betamethasone is the correct medication to anticipate the provider prescribing to hasten fetal lung maturity in clients at risk for preterm labor. It is a corticosteroid that helps promote lung maturation in the preterm fetus by stimulating the production of surfactant, which is essential for lung function. This medication is commonly given to pregnant individuals at risk of preterm delivery between 24 and 34 weeks of gestation to reduce the risk of respiratory distress syndrome in the newborn. Calcium gluconate, Indomethacin, and Nifedipine are not used to hasten fetal lung maturity in preterm labor; they serve different purposes in maternal and fetal care.

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.

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.
