Question 7

Which of the following is a key difference between diabetes mellitus and diabetes insipidus?

Accepted Answer

Diabetes mellitus is characterized by sweet-tasting urine due to glucose, while diabetes insipidus is not

Question 8

A patient presents with polyuria and polydipsia. Laboratory tests reveal blood glucose of 13 mmol/L. Which physiological mechanism best explains these symptoms?

Accepted Answer

Question 16

Which of the following is the correct sequence of events leading to polyuria in diabetes mellitus?

Accepted Answer

Elevated blood glucose → increased renal filtration of glucose → osmotic diuresis → polyuria

Accepted Answer

Diabetes leads to multiple organ complications requiring extensive medical care

Question 18

Which of the following best describes the role of homeostasis in the context of diabetes mellitus?
