Question

The parents of a five year old girl complain anxiously to

her pediatrician that in the last couple of weeks, no matter how much she eats, she keeps losing weight.
She appears quite thin, well below her normal weight. Her blood sugar is 300 (normal range 70-99).
She is diagnosed with Type I diabetes mellitus (DM 1).

In this scenario, the explanation that bests links pathophysiology with S&S in this child is that in DM1, the pancreas
a. quits producing glucagon so that glycogen stores are inaccessible, thus causing weight loss.
b. increases insulin production so that glucose stays in the blood, causing hyperglycemia.
c. quits producing insulin so that glycogenolysis is stimulated and too much glucose enters the blood.
d. quits producing insulin so that glucose cannot be used as energy in the cells, thus causing the body to burn up fat and protein for energy.

Answer 1

In Type 1 diabetes mellitus (DM1), the pancreas stops producing insulin, causing the body to burn up fat and protein for energy. This results in weight loss despite eating a normal amount of food.

Step-by-step explanation:

In Type 1 diabetes mellitus (DM1), the pancreas quits producing insulin so that glucose cannot be used as energy in the cells, thus causing the body to burn up fat and protein for energy. This results in weight loss despite the child eating a normal amount of food. The elevated blood sugar level (300) is due to the lack of insulin, which is necessary for glucose to enter the cells.
