A woman is 36 weeks’ gestation. Which of the following tests will be done during her prenatal visit?

Correct Answer: C

Rationale: In prenatal care, conducting vaginal and rectal cultures (Option C) is crucial during a woman's prenatal visit at 36 weeks' gestation. These cultures help assess for any potential infections that could be passed to the baby during labor and delivery, allowing for timely treatment and prevention of complications. The other options are not typically done at 36 weeks' gestation: A) Glucose challenge test is usually performed around 24-28 weeks to screen for gestational diabetes. B) Amniotic fluid volume assessment is typically done in the third trimester if there are concerns about fetal well-being. D) Karyotype analysis is not a routine test during prenatal visits but may be done in cases where there are specific indications for genetic testing. Educationally, understanding the timing and rationale behind each prenatal test is essential for healthcare providers to provide optimal care for pregnant women and their babies. It ensures appropriate monitoring, timely interventions, and overall positive outcomes for both mother and child.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) June 27, 2013. Nagele's rule is a standard method used to estimate the expected date of delivery (EDD) by adding 7 days to the first day of the last menstrual period (LMP), subtracting 3 months, and then adding a year. Using this rule, the nurse would calculate the EDD as June 27, 2013. Option A) May 30, 2013, is incorrect because it does not account for the correct calculation using Nagele's rule. Option B) June 20, 2013, is also incorrect as it does not follow the proper calculation method. Option D) July 3, 2013, is wrong as it does not align with Nagele's rule calculation based on the LMP provided. Educationally, understanding how to calculate the estimated date of delivery is crucial for healthcare providers working in maternal-fetal care. It helps in monitoring the progress of the pregnancy, scheduling prenatal visits, and assessing fetal growth and development. Nagele's rule is a simple yet effective method that aids in predicting the EDD and is a fundamental concept in obstetric pharmacology and care.

Correct Answer: D

Rationale: In the context of pharmacology and maternal fetal monitoring, the correct B vitamin that a vegan should supplement is B12 (cobalamin). This is because vitamin B12 is primarily found in animal products, making it a crucial nutrient for vegans who do not consume animal-derived foods. Vitamin B12 plays a key role in neurological function, red blood cell formation, and DNA synthesis, making it essential during pregnancy to support both maternal and fetal health. A deficiency in B12 can lead to serious complications such as megaloblastic anemia and neurological issues. Examining the other options: - A) B1 (thiamine) is important for energy metabolism but is not specifically lacking in a vegan diet. - B) B2 (niacin) is involved in energy production but is also not typically deficient in vegans. - C) B6 (pyridoxine) is essential for protein metabolism and neurotransmitter synthesis, but it is more readily available in plant-based foods compared to B12. In an educational context, it is important for healthcare providers working with pregnant vegan patients to be aware of the specific nutrients that may be lacking in their diet and to recommend appropriate supplements to ensure optimal maternal and fetal health. Proper education on vegan nutrition and supplementation can help prevent deficiencies and associated complications during pregnancy.

Correct Answer: D

Rationale: When counseling a Chinese immigrant, the nurse should consider cultural beliefs and practices that may impact maternal and fetal health. Option D, "Many Chinese believe strawberries cause birth defects," is the correct choice. This is important because understanding and respecting cultural beliefs can help build trust and improve communication with the patient. Options A, B, and C are incorrect because they do not directly address a specific cultural belief that could impact maternal or fetal health. While it is important for the nurse to be aware of dietary habits and health conditions prevalent in certain populations, in this case, the focus is on a specific cultural belief regarding strawberries and birth defects. In an educational context, this question highlights the importance of cultural competence in healthcare. Nurses and healthcare providers need to be sensitive to the cultural beliefs and practices of their patients to provide holistic and patient-centered care. Understanding and addressing cultural beliefs can lead to better outcomes and patient satisfaction. It also emphasizes the need for effective communication and counseling strategies that take into account the cultural background of the patient.

Correct Answer: B

Rationale: The correct answer is B) Strawberries and potatoes. Vitamin C, also known as ascorbic acid, is essential during pregnancy for fetal development and maternal health. Strawberries and potatoes are rich natural sources of vitamin C, crucial for collagen synthesis, iron absorption, and immune function. Barley, brown rice, buckwheat, lentils, wheat flour, and figs are not significant sources of vitamin C compared to strawberries and potatoes. Educationally, understanding dietary sources of essential nutrients like vitamin C is vital for nurses working in maternal-fetal care. Recommending the right foods can help pregnant women meet their nutritional needs, supporting healthy pregnancies and reducing the risk of complications. Nurses should be knowledgeable about nutrition to provide accurate guidance and support to pregnant women in optimizing their health and the health of their babies.
