Answer:

The health professional who takes care of the case of the boy with fragile X syndrome should know that it is common for patients with this syndrome to have mitral valve prolapse.

Explanation:

Fragile X syndrome (FXS or SXF) is a genetic and hereditary condition, responsible for a large number of cases of mental deficiency and behavioral disorders, affecting one in 2,000 boys and one in 4,000 women. The syndrome is caused by mutations in the FRM1 gene present in a flaw called the fragile site located at the end of the long arm of the X chromosome.

For many carriers of the mutation, fragile X syndrome is asymptomatic. However, it is common for individuals with this syndrome to present behavioral disorders and intellectual impairment that can be present in different degrees, from mild learning or speech difficulties.

Some physical characteristics may suggest the presence of the syndrome from birth. This is the case of macrocephaly and low muscle tone. There are other subtle signs of the syndrome that become more evident with growth. They are: elongated face, large flapping ears, prominent jaw, very high and arched roof of the mouth, strabismus and myopia, joint hyperextension, hollow chest, mitral valve prolapse, recurrent otitis and, in 20% of cases, convulsions.

tatyana61 [14]

Answer:

Exercises that are at risk of falling or colliding should be avoided during pregnancy, such as horse riding, skiing and judo. Diving may also not be a good thing, as the baby still has no protection against pressure change.  But exercises like yoga, is recommended to anytime of pregnancy.

Explanation:

   During pregnancy, there are women who dont do physical activity for fear of causing an abortion or harming the baby. However, physical exercises for pregnant women help strengthen muscles and promote numerous physical and psychological benefits.  Despite the good points, pregnancy is not a time for overeating - especially for women who were sedentary before getting pregnant. For each quarter, there are recommended activities that vary in frequency, duration, and intensity.

  In the third trimester, as the prospective mother will be bigger and heavier, she could feel more tired while exercising. Difficulty breathing and more go to bathroom are expected. Also, as the baby grows, the pressure against the stomach increases, which can cause heart burning.
