Final answer:
Increased thirst and excessive urination are specific signs of hyperglycemia.
Step-by-step explanation:
The specific signs of hyperglycemia that should be included on the list are increased thirst and excessive urination. When a person has hyperglycemia, the high levels of glucose in their blood draw water into the urine, causing increased urine output. This excessive urination can leave the person dehydrated, leading to increased thirst as their body tries to compensate for the water loss.
