Answer to Question 1

Ans: C
Lead poisoning is a problem that affects children younger than age 6 the most due to the fact that they are crawling on the ground and putting things in their mouths, and their developing neurologic system is more sensitive to the effects of lead. The liver and kidney development is not an influence on the degree of lead found in children's blood specimens. Metabolism is not the greatest influence on the reason why only the younger children have been impacted by lead poisoning.

Answer to Question 2

Ans: B
With Addison disease, the child would exhibit hyperkalemia, hyponatremia, and hypoglycemia. Hypercalcemia would be associated with hyperparathyroidism .
