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 B: "Although oxytocin was responsible for your orgasm it is very unlikely that it will stimulate preterm labor." This answer is correct because oxytocin, the hormone released during orgasm, is not typically enough to induce preterm labor at 26 weeks of gestation. It is important to reassure the patient in this situation to alleviate her fears and anxiety. Option A is incorrect because drinking water and monitoring for back pressure may not be the most appropriate response to this situation. Option C is not the best choice as it may cause unnecessary stress and inconvenience to the patient by rushing her to the hospital without a clear medical indication. Option D is also not ideal as a warm shower and fetal kick count assessment are not directly addressing the patient's concerns about preterm labor after orgasm. In an educational context, it is crucial for healthcare providers to have a good understanding of the physiology of pregnancy and be able to provide accurate information and reassurance to patients. This case highlights the importance of effective communication and patient education in addressing common concerns related to pregnancy and sexual activity.

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, understanding proper nutrition during pregnancy is crucial for maternal and fetal health. The correct answer, option B) 2 eggs, is equivalent to a 2 oz protein serving. Eggs are not only a good source of high-quality protein, but they also contain essential nutrients like choline which is important for fetal brain development. Option A) 4 tbsp peanut butter is not equivalent to a 2 oz protein serving as the quantity provided is not a standard measure of protein. Peanut butter is a good source of protein but the serving size does not align with the question. Option C) 1 cup cooked lima beans is not equivalent to a 2 oz protein serving as the quantity provided is much larger than the specified serving size in the question. While lima beans are a vegetarian source of protein, the portion size is not accurate. Option D) 2 ounces mixed nuts is also not equivalent to a 2 oz protein serving as nuts are more commonly associated with healthy fats rather than being a primary source of protein. The protein content in mixed nuts may vary depending on the types of nuts included. Educationally, this question highlights the importance of understanding portion sizes and protein sources during pregnancy. It emphasizes the need for pregnant individuals to consume adequate amounts of protein to support the growth and development of the fetus. A clear understanding of proper nutrition can help prevent complications and promote overall health during pregnancy.

Correct Answer: B

Rationale: The correct answer is B) Iron-deficiency anemia. Pica, the craving and consumption of non-food substances, such as ice, clay, or paper, during pregnancy can lead to iron-deficiency anemia. This is because the ingestion of non-nutritive substances can interfere with the body's ability to absorb iron from food, leading to a deficiency in this essential mineral. Iron-deficiency anemia during pregnancy can have serious consequences, such as preterm birth, low birth weight, and developmental delays in the baby. Option A) Hypothyroidism is not directly associated with pica during pregnancy. Hypothyroidism is a separate condition caused by an underactive thyroid gland. Option C) Hypercalcemia, an excess of calcium in the blood, is not typically linked to pica during pregnancy. It is usually associated with conditions like hyperparathyroidism or certain cancers. Option D) Overexposure to zinc is not a common complication of pica during pregnancy. While excessive zinc intake can cause toxicity symptoms, it is not a primary concern related to pica. Educationally, understanding the complications associated with pica during pregnancy is crucial for healthcare providers working with pregnant women. By recognizing the risks, providers can offer appropriate interventions and support to prevent and address potential complications like iron-deficiency anemia. This knowledge can contribute to better maternal and fetal outcomes during pregnancy.

Correct Answer: C

Rationale: In fetal circulation, the correct statement is C) Right atrium contains mixed blood. This is because the right atrium receives deoxygenated blood from the body through the superior and inferior vena cava, as well as oxygenated blood from the placenta through the umbilical vein. This blood is mixed in the right atrium before being pumped to the lungs for oxygenation. Option A is incorrect because the foramen ovale is a shunt between the right and left atria, not the ventricles. Option B is incorrect as the umbilical vein actually carries oxygen-rich blood from the placenta to the fetus. Option D is incorrect because the ductus venosus is a shunt that bypasses the liver and connects the umbilical vein to the inferior vena cava, not between the aorta and pulmonary artery. Understanding fetal circulation is crucial in maternal monitoring as it helps healthcare providers assess the well-being of the fetus and detect any abnormalities that may impact fetal development or delivery. Knowing the correct pathways of blood flow in the fetal heart is essential for recognizing and managing potential complications during pregnancy.
