A nurse is caring for a patient who has Diabetes Insipidus. Which of the following urinalysis laboratory findings should the nurse expect?
Decreased urine specific gravity
Presence of insulin
Presence of glucose
Presence of ketones
The Correct Answer is A
A. Specific gravity measures the concentration of solutes in urine. In diabetes insipidus, the urine is very dilute, so the specific gravity will be low.
B. Insulin is related to diabetes mellitus, not diabetes insipidus. There would be no insulin in the urine in this case.
C. Glucose in the urine is typically associated with diabetes mellitus, not diabetes insipidus.
D. Presence of ketones: Ketones are typically found in the urine during uncontrolled diabetes mellitus or starvation. They would not be present in diabetes insipidus.
