Final answer:
Pallor and diaphoresis are not signs or symptoms of hyperglycemia; they are more associated with hypoglycemia.
Step-by-step explanation:
The student asked which of the following is NOT a sign or symptom of hyperglycemia: a. gradual onset, b. abdominal pain, c. severe thirst, d. pallor and diaphoresis. The correct answer is d. pallor and diaphoresis, as these are symptoms more commonly associated with hypoglycemia. On the other hand, hyperglycemia is characterized by symptoms such as gradual onset, severe thirst (polydipsia), as well as other noted symptoms like frequent urination (polyuria) and increased hunger (polyphagia).
