For a client with fruity breath odor and extreme thirst, which condition should the nurse suspect?

• A. Dehydration
• B. Diabetes mellitus
• C. Kidney failure
• D. Respiratory acidosis

Answer: (B)

The presence of fruity breath odor, often described as similar to that of ripe fruit or nail polish remover, is a hallmark sign of diabetic ketoacidosis (DKA), which can occur in clients with poorly controlled diabetes mellitus. This condition arises due to the breakdown of fat for energy when glucose is unavailable, leading to the production of ketones. Acetone, one of the ketones, is responsible for the characteristic fruity smell. Extreme thirst, or polydipsia, often accompanies this condition as the body attempts to compensate for the high levels of glucose in the bloodstream. When blood glucose levels are elevated, glucose spills into the urine, taking water with it, which leads to dehydration and an intense feeling of thirst. Diabetes mellitus encompasses a range of symptoms and complications, including the specific signs of diabetic ketoacidosis, making it the most fitting condition to suspect based on the symptoms presented. Other conditions listed do not typically manifest with fruity breath odor or such extreme thirst as primary symptoms, making the identification of diabetes mellitus crucial in this scenario.
