Answer to Question 1

ANS: C
Infants are tested for DI with desmopressin (DDAVP) instead of a water deprivation test. After administering the medication, urine osmolality is tested at baseline and every 30 minutes for the next 2 hours. The nurse must collect the urine. An indwelling catheter is needed to obtain samples so frequently. A urine collection bag collects the urine but the infant may not void every 30 minutes. If no increase is seen in the osmolality, the infant may have hereditary nephrogenic DI, which can be confirmed by subsequent DNA testing. Because the child is not deprived of water, there is no need for an IV.

Answer to Question 2

ANS: D
A Medic-Alert bracelet, medications, and a water bottle are all important for the child with DI to have with him or her. However, preventing dehydration takes priority, so the most important item is the water bottle or other ready access to water.
