Final answer:
Hypoglycemia is not a causative factor or associated symptom of diabetic ketoacidosis; rather, DKA is characterized by hyperglycemia, increased ketogenesis, and acidosis which may cause hyperventilation.
Step-by-step explanation:
Among the options provided, the one that is not a causative factor or associated symptom of diabetic ketoacidosis (DKA) is D. Hypoglycemia. Diabetic ketoacidosis is typically characterized by hyperglycemia (high blood sugar), ketogenesis (increased production of ketone bodies), and acidification of the blood, leading to symptoms such as hyperventilation to compensate for the low blood pH. Hypoglycemia, or low blood sugar, is not consistent with the hyperglycemic state of DKA.
The symptoms of DKA include hyperventilation, frequent urination, excessive thirst, and fruity-smelling breath. However, hypoglycemia is not a causative factor or associated symptom of DKA.
