Final answer:
In diabetic ketoacidosis, increased urination is a key symptom due to the osmotic effect of high blood glucose levels and the kidneys attempting to excrete excess ketone bodies.
Step-by-step explanation:
A nurse admitting a client who has diabetic ketoacidosis should expect to find certain symptoms indicative of the condition. Among these symptoms, increased urination (b. Increased urination) is a key finding associated with diabetic ketoacidosis. This happens because high glucose concentration in the blood creates an osmotic effect that pulls water into the urine, leading to frequent urination. Additionally, the excess of ketone bodies may lead to ketoacidosis, characterized by increased levels of acids (ketone bodies) in the blood, which the kidneys try to excrete, contributing further to urinary frequency.
