Which of the following are signs and symptoms of diabetic coma or ketoacidosis?

The correct answer highlights two key indicators associated with diabetic coma or ketoacidosis: fruity smelling breath and mental confusion. In diabetic ketoacidosis, the body breaks down fat for fuel due to an insufficient supply of insulin. This process leads to the production of ketones, which can result in a sweet or fruity odor on the breath. Mental confusion occurs because the altered levels of blood sugar and ketones can impact brain function, causing cognitive disturbances.

While the other options contain symptoms that individuals may experience due to various medical conditions, they do not specifically target the classic signs of diabetic coma or ketoacidosis, making them less correct in this context. Therefore, identifying fruity smelling breath along with mental confusion is crucial for recognition and early intervention in cases of diabetic complications.
