How does maternal obesity affect pregnancy outcomes?

Correct Answer: A

Rationale: The correct answer is A: Increases risk of gestational diabetes. Maternal obesity can lead to insulin resistance, increasing the likelihood of developing gestational diabetes during pregnancy. This condition can have negative effects on both the mother and the baby. B: Miscarriage is not directly linked to maternal obesity but can be influenced by other factors. C: Maternal obesity is not a direct cause of anemia during pregnancy. Anemia is usually related to iron deficiency or other factors. D: Maternal obesity is actually associated with an increased risk of preterm labor, not a reduced chance. This is due to various complications such as hypertension and preeclampsia.

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.

Correct Answer: B

Rationale: Breech presentation refers to the bottom or feet-first position of the baby in the uterus. This is the correct answer (B) because it accurately defines breech presentation. Choice A (head-first presentation) is incorrect as it describes the typical vertex presentation. Choices C (oblique lie) and D (transverse lie) are also incorrect as they refer to other abnormal fetal positions that are different from breech presentation.
