A placenta previa in which the placental edge just reaches the internal os is more commonly known as:

Choice A reason: Diabetes mellitus is not a direct consequence of inadequate weight gain during pregnancy for the infant. However, maternal diabetes can increase the risk of fetal macrosomia (large birth weight), congenital anomalies, and neonatal hypoglycemia (low blood sugar) in the infant.

Choice B reason: Down syndrome is not a direct consequence of inadequate weight gain during pregnancy for the infant. Down syndrome is a genetic disorder caused by an extra copy of chromosome 21 in the cells of the fetus. The risk of having a baby with Down syndrome increases with maternal age, but it is not related to maternal weight or nutrition².

Choice C reason: Spina bifida is not a direct consequence of inadequate weight gain during pregnancy for the infant. Spina bifida is a neural tube defect that occurs when the spine and spinal cord do not form properly in the fetus. The main risk factor for spina bifida is a lack of folic acid (a B vitamin) in the mother's diet before and during pregnancy.

Choice D reason: Intrauterine growth restriction (IUGR) is a condition in which the fetus does not grow as expected and has a low birth weight. IUGR can have many causes, such as placental problems, infections, chromosomal abnormalities, and maternal factors. One of the maternal factors that can contribute to IUGR is inadequate weight gain during pregnancy, especially in underweight women. IUGR can increase the risk of complications for the infant, such as preterm birth, low Apgar score, hypothermia, hypoglycemia, and breathing problems⁵.

Choice A reason: An antiemetic such as pyridoxine may be used to control vomiting in women with hyperemesis gravidarum, but it is not the initial treatment. The first priority is to restore fluid and electrolyte balance and prevent dehydration and hypovolemia.

Choice B reason: IV therapy is the initial treatment for women with hyperemesis gravidarum. It helps to correct fluid and electrolyte imbalances, prevent dehydration and hypovolemia, and restore normal blood pressure and urine output. IV fluids may also contain glucose, vitamins, and electrolytes to replenish losses.

Choice C reason: Enteral nutrition may be used to meet nutritional needs in women with hyperemesis gravidarum, but it is not the initial treatment. Enteral nutrition involves feeding through a tube inserted into the stomach or intestine. It may be considered if oral intake is not tolerated or adequate after IV therapy.

Choice D reason: Corticosteroids are not used to treat hyperemesis gravidarum. They are used to reduce inflammation in conditions such as asthma, rheumatoid arthritis, and allergic reactions. They have no effect on nausea and vomiting in pregnancy.
