A healthcare provider in a clinic is reinforcing teaching with a client of childbearing age about recommended folic acid supplements. Which of the following defects can occur in the fetus or neonate as a result of folic acid deficiency?

Correct Answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid is crucial for neural tube development in the fetus. Without sufficient folic acid, neural tube defects like spina bifida can occur. Iron deficiency anemia (A) is not directly related to folic acid deficiency. Poor bone formation (B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (C) refers to excessive fetal growth, not a direct consequence of folic acid deficiency. In summary, folic acid deficiency primarily increases the risk of neural tube defects in the fetus or neonate.

Correct Answer: D

Rationale: The correct answer is D because it demonstrates an understanding of the importance of calcium intake for breastfeeding mothers. Calcium is essential for both the mother's health and the baby's bone development. Continuing calcium supplements shows a commitment to meeting nutritional needs. Incorrect choices: A: Having coffee is fine, but it's not directly related to postpartum nutrition needs. B: Folic acid is important for pregnancy but not specifically for increasing milk supply. C: While additional calories are needed during breastfeeding, the specific amount varies and is not always 330 calories per day.

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.

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.

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.
