Which nursing interventions is the most appropriate to perform initially?

A client with head trauma that develops a urine output of 300 ml/hr, dry skin, and dry mucous membranes should have their urine specific gravity evaluated by the nurse. Diabetes insipidus is a result of a urine output of 300 ml/hr.

The nurse cannot anticipate treatment for renal failure because there is no evidence of it. Emollients to prevent skin breakdown are important, but the nurse does not need to worry about performing this immediately. The nurse should not slow the rate of IV fluid when polyuria is present because it would contribute to dehydration.
