9780323583426. A patient diagnosed with diabetic ketoacidosis (DKA) has thefollowing laboratory values:arterial pH 7.20; serum glucose 500 mg/dL; positive urine glucose and ketones; serumpotassium (K+) 2 mEq/L; serum sodium (Na+) 130 mEq/L. The patient reports that hehasbeen sick with the “flu” for 1 week. What relationship do these values have to his insulindeficiency?a. Increased glucose use causes the shift of fluid from the intravascular to theintracellular space.b. Decreased glucose use causes fatty acid use, ketogenesis, metabolic acidosis, andosmotic diuresis.c. Increased glucose and fatty acids stimulate renal diuresis, electrolyte loss, andmetabolic alkalosis.d. Decreased glucose use results in protein catabolism, tissue wasting, respiratoryacidosis, and electrolyte loss.Decreased glucose causes fatty acid use, ketogenesis, metabolic acidosis, and osmoticdiuresis, which have resulted in the symptoms listed in the question. Glucose is notbeing usedwhich accounts for the high serum glucose. The pH indicates acidosis, not alkalosis.DKA is ametabolic, not respiratory, process.

b. Chronic insulin resistancec. Elevation in serum glucosed. Increase in antidiuretic hormoneGlucose accumulates in the blood and appears in the urine as the renal threshold forglucose isexceeded, producing an osmotic diuresis and the symptoms of polyuria and thirst.Ketoneformation would lead to acidosis. Insulin resistance will promote hyperglycemia. Andincrease in antidiuretic hormone leads to water retention.PTS: 1 DIF: Cognitive Level: Remembering
