Final answer:
A fruity odor is associated with isopropanol poisoning, due to the production of acetone during its metabolism.
Step-by-step explanation:
A patient with isopropanol poisoning may present with a fruity odor. This is due to the presence of acetone, which is produced in the liver during the metabolism of isopropanol and is excreted through the lungs. Acetone carries a characteristic sweet or fruity smell, which is also noticeable in the breath of diabetic patients in ketoacidosis or individuals in a state of starvation.
It is important to differentiate the smell associated with isopropanol poisoning from other compounds, as different odors may indicate different types of poisoning or underlying medical conditions. For example, thiols are compounds that can create a range of smells, including those similar to onions or garlic, and are not associated with isopropanol poisoning.
