A nurse is reinforcing teaching with the mother of a newborn who is small for gestational age. Which of the following should the nurse include as a cause of this condition?

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:

This statement is incorrect because special lights are used to treat jaundice, not PKU. Jaundice is a condition that causes yellowing of the skin and eyes due to high levels of bilirubin in the blood. Bilirubin is a waste product that is normally removed by the liver. Special lights help break down bilirubin so that it can be excreted from the body.

Choice B reason:

This statement is correct because PKU is a genetic disorder that can be corrected by diet. PKU is caused by a lack of an enzyme that breaks down phenylalanine, an amino acid found in protein-rich foods. Phenylalanine can build up in the blood and cause brain damage and other health problems if not treated. A diet that is low in phenylalanine and high in a special formula can prevent these complications.

Choice C reason:

This statement is correct because sometimes the test is repeated in the doctor's office at the 2-week check-up. The PKU test is done one to three days after birth, but it may not be accurate if the baby has not had enough protein in their diet before the test. A repeat test may be needed to confirm or rule out PKU.

Choice D reason:

This statement is incorrect because the baby must take formula or breast milk after the test is done, not before. The test measures the level of phenylalanine in the blood, which will be higher if the baby has eaten protein-rich foods. The test should be done after the baby has fasted for at least two hours.
