What causes congenital hip dysplasia?

Choice A reason:

Small for gestational age (SGA) newborns are at risk for respiratory distress syndrome (RDS) and respiratory acidosis because they have immature lungs that produce less surfactant, which is needed to keep the alveoli open and prevent atelectasis. SGA newborns also have less glycogen stores, which can lead to hypoglycemia and impaired oxygen delivery to the tissues.

Choice B reason:

Maternal history of asthma is not a risk factor for RDS or respiratory acidosis in the newborn. Asthma is a chronic inflammatory disorder of the airways that affects the mother, not the fetus. Maternal asthma can cause complications such as preterm labor, preeclampsia, or intrauterine growth restriction, but it does not directly affect the fetal lung development or function.

Choice C reason:

Ventricular septal defect (VSD) is a congenital heart defect that causes a hole in the wall between the ventricles of the heart. This can result in increased pulmonary blood flow and pressure, which can lead to pulmonary edema and heart failure in the newborn. However, VSD does not cause RDS or respiratory acidosis, which are related to lung maturity and surfactant production.

Choice D reason:

Cesarean birth is not a risk factor for RDS or respiratory acidosis in the newborn. Cesarean birth can increase the risk of transient tachypnea of the newborn (TTN), which is caused by delayed absorption of fetal lung fluid. TTN usually resolves within 24 to 48 hours and does not cause a significant acid-base imbalance in the newborn.

Choice A reason:

Swimming is one of the best and safest exercises for pregnant women. It exercises your large muscle groups, provides cardiovascular benefits, reduces swelling, and allows you to feel weightless. Swimming is also a low-impact exercise that does not put too much stress on your joints and muscles. Therefore, this statement does not indicate a need for additional teaching.

Choice B reason:

Racquetball is not an appropriate exercise during pregnancy. It is a high-impact sport that involves sudden changes of direction, quick movements, and the risk of falling or getting hit by the ball or the racquet. These factors can increase the chance of injury, bleeding, or premature labor. Therefore, this statement indicates a need for additional teaching.

Choice C reason:

Cycling on a stationary bike is a safe exercise during pregnancy. It provides moderate aerobic conditioning and relieves stress and tension in your joints and muscles. Cycling on a stationary bike also reduces the risk of falling or losing balance compared to cycling on a regular bike. Therefore, this statement does not indicate a need for additional teaching.

Choice D reason:

Yoga is a beneficial exercise during pregnancy. It can help you relax, improve your flexibility, strengthen your muscles, and prepare your body for labor and delivery. Yoga can also help you cope with symptoms of depression and anxiety during pregnancy. However, you should avoid hot yoga or poses that involve lying flat on your back, twisting your abdomen, or compressing your belly. Therefore, this statement does not indicate a need for additional teaching.
