A nurse is caring for a preschool child with suspected diabetes insipidus. Which clinical manifestation would the nurse expect to observe?
Glycosuria
Polyuria and polydipsia
Nausea and vomiting
Oliguria
The Correct Answer is B
A. Glycosuria (presence of glucose in the urine) is not typical in diabetes insipidus, which primarily involves issues with water balance.
B. Polyuria (frequent urination) and polydipsia (excessive thirst) are hallmark symptoms of diabetes insipidus, caused by a deficiency of antidiuretic hormone (ADH) or resistance to it.
C. Nausea and vomiting can occur with many conditions but are not primary symptoms of diabetes insipidus.
D. Oliguria (low urine output) is more commonly associated with conditions like dehydration or kidney failure, not diabetes insipidus, where the issue is excessive urine production.
