Review Timby's Introductory Medical-Surgical Nursing Thirteenth, North American Edition - Caring for Clients With Diabetes Mellitus related questions and content

Which is the best nursing explanation for the symptom of polyuria in a client with diabetes mellitus?

  • A. With diabetes, drinking more results in more urine production.
  • B. Increased ketones in the urine promote the manufacturing of more urine.
  • C. High sugar pulls fluid into the bloodstream, which results in more urine production.
  • D. The body's requirement for fuel drives the production of urine.
Correct Answer: C

Rationale: High blood glucose levels increase blood osmolality, pulling fluid into the vascular system, which leads to increased urine production (polyuria) as the kidneys attempt to excrete excess glucose. This triggers thirst (polydipsia), not vice versa. Ketones and fuel requirements do not directly cause polyuria.
