Final answer:
The overproduction of ketone bodies could cause metabolic acidosis in a person with Type 1 diabetes who hasn't injected insulin for 3 days.
Step-by-step explanation:
The overproduction of ketone bodies could cause metabolic acidosis in a person with Type 1 diabetes who has not been able to inject insulin for the past 3 days. When the cells are unable to utilize glucose for energy production, they start using fats, resulting in the production of ketone bodies by the liver. Excessive production of ketone bodies increases the acidity of the blood, leading to metabolic acidosis.
