What is true regarding FAS and NAS?

Choice A reason:

Swimming is one of the best exercises for pregnant women because it provides moderate aerobic conditioning with minimal stress on your joints. It also supports your increased weight and helps you stay cool and comfortable.

Choice B reason:

Scuba diving is not a safe exercise for pregnant women because it poses a high risk of injury to the baby. The baby has no protection against decompression sickness and gas embolism, which are caused by changes in pressure underwater.

Choice C reason:

Walking is a great exercise for beginners and can be done throughout pregnancy. It improves your cardiovascular fitness, strengthens your muscles and bones, and helps prevent excessive weight gain and gestational diabetes.

Choice D reason:

Yoga can be beneficial for pregnant women as it can improve flexibility, balance, posture, breathing and relaxation. It can also reduce stress, anxiety and back pain. However, some yoga poses may not be suitable for pregnancy, so it is advisable to join a prenatal yoga class or consult a qualified instructor.

Choice E reason:

Snow skiing is not recommended for pregnant women because it involves a high risk of falling and affecting your balance. Falls can cause damage to your baby or placenta, especially in the second and third trimesters.

Choice A reason:

Maternal/newborn blood group incompatibility is the most common cause of pathologic jaundice, which appears within the first 24 hours of life. This occurs when the mother's antibodies attack the newborn's red blood cells, causing hemolysis and increased bilirubin production. The excess bilirubin causes the yellowish discoloration of the skin and mucous membranes.

Choice B reason:

The absence of vitamin K is not related to jaundice but to hemorrhagic disease of the newborn. Vitamin K is essential for blood clotting and is given to newborns as an injection shortly after birth. Newborns are at risk of vitamin K deficiency because they have low levels of vitamin K in their bodies and breast milk, and their intestinal bacteria are not yet able to synthesize vitamin K.

Choice C reason:

Maternal cocaine abuse can cause many complications for the newborn, such as prematurity, low birth weight, neonatal abstinence syndrome, neurobehavioral problems, and congenital anomalies. However, it is not a direct cause of jaundice in the newborn.

Choice D reason:

Physiologic jaundice is a normal and benign condition that affects about 60% of term newborns. It occurs due to the immature liver's inability to metabolize bilirubin effectively. It usually appears after the first 24 hours of life and peaks around the third or fourth day. It does not require treatment unless the bilirubin level is very high or rising rapidly.
