The baby dies immediately after birth due to the presence of

Correct Answer: C

Rationale: The correct answer is C: Truncus arteriosus. In this condition, there is a single large vessel arising from the heart that gives rise to the systemic, pulmonary, and coronary arteries. This results in mixing of oxygenated and deoxygenated blood, leading to severe cyanosis and inadequate oxygenation of the body, causing immediate death after birth. A: Pulmonary stenosis and B: Aortic coarctation typically do not cause immediate death after birth. D: Ductus arteriosus is a normal fetal structure that closes shortly after birth and its presence would not directly cause immediate death.

Correct Answer: D

Rationale: The correct answer is D because all the choices (A, B, and C) are risks associated with cesarean sections. Infection can occur at the incision site, blood loss is a common concern during surgery, and cesarean sections typically have a longer recovery time compared to vaginal delivery. Therefore, all of these risks are potential complications of undergoing a cesarean section. The other choices (A, B, and C) are incorrect individually because they only represent a subset of the risks associated with cesarean sections, while choice D encompasses all potential risks.

Correct Answer: D

Rationale: Maternal smoking during pregnancy can affect fetal development in multiple ways. Smoking can cause low birth weight by restricting oxygen and nutrients to the fetus, leading to growth issues. It can also increase the risk of preterm birth due to the harmful chemicals in cigarette smoke. Furthermore, smoking can affect lung development in the fetus, leading to respiratory issues. Therefore, the correct answer is D - All of the above, as maternal smoking can have a comprehensive impact on fetal development, including low birth weight, preterm birth, and lung development issues.

Correct Answer: D

Rationale: The correct answer is D, All of the above. Regular exercise helps control weight gain and improves maternal health. A balanced diet provides essential nutrients for both mother and baby. Monitoring weight gain ensures healthy weight management. Combining all three strategies optimizes outcomes by reducing risks associated with maternal obesity, such as gestational diabetes and hypertension. Each option plays a crucial role in managing maternal obesity during pregnancy for better overall health and well-being.

Correct Answer: D

Rationale: The correct answer is D: All of the above. High-risk pregnancies are associated with various complications, including preterm birth, gestational diabetes, and preeclampsia. Preterm birth can lead to developmental issues for the baby. Gestational diabetes affects the mother's and baby's health. Preeclampsia can result in high blood pressure and organ damage. Choosing D as the correct answer encompasses all these complications, highlighting the comprehensive nature of risks in high-risk pregnancies. Choices A, B, and C alone do not cover all the potential complications, making them individually incorrect.
