Fluid Deprivation Test
The fluid deprivation test involves withholding water for 4 to 18 hours and periodically checking urine and plasma osmolarity. A client with diabetes insipidus will have an increased serum osmolarity of less than 300 mOsm/kg. Urine osmolarity won't increase. The capillary blood glucose test rapidly measures glucose level in whole blood. The serum ketone test is used to diagnose diabetic ketoacidosis. The urine glucose test monitors glucose levels in urine; however, diabetes insipidus doesn't affect urine glucose levels, so this test isn't appropriate.

Fluid deprivation test-rationale: the fluid deprivation test involves withholding water for 4 to 18 hours and periodically checking urine and plasma osmolarity. a client with diabetes insipidus will have an increased serum osmolarity of less than 300 mosm/kg. urine osmolarity wont increase. the capillary blood glucose test rapidly measures glucose level in whole blood. the serum ketone test is used to diagnose diabetic ketoacidosis. the urine glucose test monitors glucose levels in urine; however, diabetes insipidus doesnt affect urine glucose levels, so this test isnt appropriate.client needs category: physiological integrityclient needs subcategory: reduction of risk potentialcognitive level: analysisreference: smeltzer, s.c., et al. brunner & suddarths textbook of medical surgical-nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1447.
