A woman, 26-weeks’ gestation, calls the triage nurse stating, 'I’m really scared. I tried not to but I had an orgasm when we were making love. I just know that I will go into preterm labor now.'

Correct Answer: B

Rationale: The correct answer is option B) Although oxytocin was responsible for your orgasm it is very unlikely that it will stimulate preterm labor. Explanation: This option is correct because oxytocin, the hormone responsible for uterine contractions during labor, is also released during orgasm. However, the amount released during sexual activity is not significant enough to induce preterm labor at 26 weeks gestation. It is important to reassure the woman that experiencing an orgasm during pregnancy is normal and does not necessarily lead to preterm labor. Why others are wrong: A) Lie down and drink a quart of water. If you feel any back pressure at all call me back right away. This option does not address the woman's concerns about preterm labor and may cause unnecessary worry or confusion. C) I will inform the doctor for you. What I want you to do is to come to the hospital right now to be checked. This option may cause unnecessary alarm and lead to an unnecessary visit to the hospital without proper justification, potentially increasing the woman's anxiety and stress. D) The best thing for you to do right now is to take a warm shower and then do a fetal kick count assessment. This option does not address the woman's concerns about preterm labor after experiencing an orgasm during pregnancy. Fetal kick counts are important but are not the immediate priority in this scenario. Educational context: It is crucial for healthcare providers to offer accurate and reassuring information to pregnant women to alleviate their fears and ensure their well-being. Understanding the physiological changes that occur during pregnancy, such as the release of oxytocin during sexual activity, can help healthcare professionals provide appropriate guidance and support to expectant mothers. Empowering women with knowledge about their bodies can enhance their confidence and reduce unnecessary anxiety during pregnancy.

Correct Answer: A

Rationale: Tofu, legumes, and broccoli provide essential nutrients like protein, iron, and calcium that are often lacking in a vegan diet. Corn, yams, and green beans offer carbohydrates and vitamins but lack sufficient protein sources. Potatoes, parsnips, and turnips are starchy vegetables with limited nutritional variety. Cheese, yogurt, and fish are non-vegan options.

Correct Answer: B

Rationale: In the context of pharmacology and external maternal monitoring, understanding proper nutrition during pregnancy is crucial to ensure the health and well-being of both the mother and the developing fetus. When it comes to protein intake, it is important for pregnant women to consume an adequate amount to support the growth and development of the baby. The correct answer, option B) 2 eggs, is equivalent to a 2 oz protein serving. Eggs are a high-quality source of protein and provide essential nutrients like choline, which is important for fetal brain development. Option A) 4 tbsp peanut butter may contain approximately 8 grams of protein, but the serving size may not necessarily equate to a 2 oz protein serving. Option C) 1 cup cooked lima beans contains protein, but the volume required to reach a 2 oz serving may exceed a typical serving size. Option D) 2 ounces mixed nuts also contain protein, but the protein content can vary depending on the types of nuts included, and the serving size may not precisely match a 2 oz protein serving. Educationally, understanding portion sizes and protein equivalents is vital for pregnant women to maintain a balanced diet. By selecting the correct answer, students learn the importance of choosing appropriate protein sources during pregnancy to support maternal and fetal health.

Correct Answer: B

Rationale: In the context of pharmacology and maternal health, understanding the association between pica during pregnancy and iron-deficiency anemia is crucial. Pica, the craving and consumption of non-food substances, can lead to decreased intake of essential nutrients like iron, resulting in anemia. During pregnancy, the body's demand for iron significantly increases to support fetal development and maternal blood volume expansion. Iron-deficiency anemia in pregnancy poses risks such as preterm birth, low birth weight, and maternal complications. Option A, hypothyroidism, is not directly associated with pica during pregnancy. Hypothyroidism is a separate endocrine disorder that can affect fertility and pregnancy outcomes but is not linked to pica behavior. Option C, hypercalcemia, refers to elevated levels of calcium in the blood and is not typically caused by pica during pregnancy. Hypercalcemia can result from various medical conditions but is not a common consequence of pica behavior. Option D, overexposure to zinc, is not the primary concern associated with pica during pregnancy. While excessive zinc intake can lead to toxicity symptoms, pica's main risk during pregnancy lies in the development of nutrient deficiencies like iron-deficiency anemia. Educationally, this question highlights the importance of recognizing the potential consequences of pica during pregnancy, emphasizing the need for proper nutrition and prenatal care. Healthcare providers must educate pregnant individuals about healthy eating habits, monitor for unusual cravings or behaviors, and provide appropriate interventions to prevent complications like iron-deficiency anemia. Understanding these connections is vital in promoting maternal and fetal well-being during pregnancy.

Correct Answer: C

Rationale: In fetal circulation, the correct statement is that the right atrium contains mixed blood. This is because the right atrium receives deoxygenated blood from the fetal body through the inferior vena cava and oxygenated blood from the placenta via the umbilical vein. The blood mixes in the right atrium and is then pumped to the left atrium through the foramen ovale, a hole in the atrial septum that allows blood to bypass the fetal lungs. Option A is incorrect because the foramen ovale is actually a communication between the two atria, not the ventricles. Option B is incorrect as the umbilical vein carries oxygen-rich blood from the placenta to the fetus. Option D is also incorrect as the ductus venosus is a vessel that shunts oxygenated blood from the umbilical vein directly to the inferior vena cava, bypassing the liver. Understanding fetal circulation is crucial in obstetrics and pharmacology as it impacts how medications given to the mother may affect the fetus. Knowledge of fetal circulation helps healthcare providers monitor fetal well-being during pregnancy and labor, allowing for timely interventions if any issues arise. It also provides insight into congenital heart defects that may affect fetal development.
