Answer to Question 1

F
Parental consanguinity (blood relationships) increases the risk of having a child with an
autosomal recessive disorder.

Answer to Question 2

4
Rationale:
1. In children younger than 6 years old, the chest and abdomen rise simultaneously because the diaphragm is the primary breathing muscle.
2. The anteroposterior diameter becomes smaller than the lateral diameter after around 1 year of age.
3. Bronchovesicular breath sounds are normal.
4. A protruding sternum is an abnormal chest shape, and is called pigeon chest (pectus carinatum).
