Which of the following signs or symptoms would a patient with new-onset type 1 diabetes MOST likely exhibit?

A patient with new-onset type 1 diabetes is most likely to exhibit weight loss and polyuria due to the body's inability to effectively utilize glucose for energy. In this condition, the pancreas produces little to no insulin, which is essential for allowing glucose to enter cells. As a result, glucose accumulates in the bloodstream, leading to high blood glucose levels.

The body, experiencing a "starvation" state because it cannot utilize glucose, begins to break down fat and muscle for energy, resulting in weight loss. Polyuria, or increased urination, occurs as the kidneys attempt to eliminate excess glucose from the body, leading to osmotic diuresis. This increased urination can also contribute to dehydration, further exacerbating symptoms.

The other options suggest conditions that are not characteristic of new-onset type 1 diabetes. For instance, weight gain and edema would generally indicate an entirely different metabolic state, potentially involving fluid retention, which is not typical in this scenario. A low blood glucose level is also not common; in fact, patients usually present with high blood glucose due to the lack of insulin. Lastly, a total lack of appetite can occur but is not as specifically indicative of new-onset type 1 diabetes compared to the noticeable symptoms of
