Correct Answer: C

Rationale: In this scenario, the symptoms of continued nausea, vomiting, scant prune-colored discharge, and a fundal height larger than expected at 4 months of gestation suggest a possible hydatidiform mole. Hyperemesis gravidarum (choice A) typically presents with severe nausea, vomiting, weight loss, and electrolyte imbalances. Threatened abortion (choice B) is characterized by vaginal bleeding with or without cramping but does not typically present with prune-colored discharge. Preterm labor (choice D) manifests with regular uterine contractions leading to cervical changes and can occur later in pregnancy.

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: During early pregnancy, common discomforts include breast tenderness due to hormonal changes, urinary frequency caused by increased blood flow to the kidneys, and epistaxis (nosebleeds) due to increased blood volume and hormonal changes. Educating the client about these discomforts helps them understand what to expect during this stage. Choice D, 'All of the above,' is the correct answer because all the listed findings are common discomforts experienced during early pregnancy. Choices A, B, and C are individually correct as well, as breast tenderness, urinary frequency, and epistaxis are all common discomforts that pregnant individuals may encounter.

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: A

Rationale: To calculate the estimated date of delivery, add 7 days to the first day of the last menstrual period (April 1st), which gives April 8th. Then, count forward 9 months from April 8th, leading to January 8th as the estimated date of delivery. Choice A is correct. Choice B is incorrect because it is exactly 9 months from the last menstrual period without accounting for the additional 7 days. Choices C and D are incorrect as they fall in February, which is beyond the 9-month period from the last menstrual period.
