SCI 225 Week 16 Pathophysiology Final Exam (Proctored) 2021 A patient with type 1 diabetes asks the nurse what causes polyuria. What is the nurse’s best response? The symptom of polyuria in diabetes mellitus (DM) is caused by: a reduced ADH response caused by insulin deficiency. the loss of protein across the glomerular membrane. the production of ketones. increased glucose in the urine. The presence of glucose in the urine filtrate draws water into the tubules, causing ...
